  Stone crushing equipment: a vital contributor to sustainable construction
Posté par : DFDVX44 - 03-12-2021, - Forum : Présentez-vous... - Pas de réponse

Stone crushing equipment: a vital contributor to sustainable construction 
Stone Crushers are extensively used to crush bulk and heavy stones into different sizes efficiently and reliably, be it at quarries or recycling plants. There has been a considerable rise in mining activities across the world to meet the burgeoning requirement of valuable minerals or other geological materials. Global stone crushing equipment market size is anticipated to hit US$8.5 billion by 2025, with the consistent deployment of jaw and impact crushers.
A rise in urbanization, along with the increase in transportation activities across the globe is coercing governments to develop roads and highways. Increasing establishment of factories, SEZs, residential properties and corporate offices in developing nations is furthermore pushing infrastructure spending. Like much other large equipment used in industrial and construction settings, stone crushing plants are also bound by environmental policies.

When mining natural river sand or making artificial sand, also called machine-made sand, manufactured sand, M-sand, mud and other impurities are mixed into it, which can easily cause unwashed sand and gravel to condense together when stored, thereby reducing the performance of sand and gravel. While the well-washed sand has a good use effect and high market price. The Sand Making Machine &Sand Washing Machine is satisfied with the demand and became the darling of the market.
A sand washing plant with a scientific and reasonable configuration will effectively improve productivity, make customers recover costs in a shorter time, and reap more considerable economic interest.
If the raw material is natural sand such as river sand, mountain sand, or the unwashed sand you bought, there should be siloes, vibrating screens, sand washers, dewatering machines, and belt conveyors in the sand washing plant.

One machine that is heavily used for crushing and grinding tasks is the ball mill. This machine is described as a grinding device, capable to crush and transform large hard materials into fine powder. A Grinding Ball Mill is a cylindrical machine, generally used for mashing and crushing paints, ceramic materials, ores, and other hard materials. By rotating on the horizontal axis, the ball mill effectively turns hard materials into fine powder. There are different ball mills on the market, but all of them use the same working principle and are consist of the same elements. For example, grinding materials can be found in every ball mill.

Due to the different particle size composition of gold in placer gold mines, the effective particle size limits of materials processed by various gravity separation equipment are also different. Usually, the placer gold Ore Beneficiation Equipment mostly uses centrifugal concentrators as the roughing equipment. When the processing capacity is large, a jig can be used to concentrate before the centrifuge so as to reduce the quantity of centrifuge. The shaking table is always used as cleaning equipment for the centrifuge concentrates. The sluice box which is a traditional way can be used for the tailings of the centrifuge, or directly for the output of screening. Therefore, the reasonable beneficiation process of placer gold ore is mostly the combined operation of several gravity separation equipment.

Coal drying technology is divided into drum drying and drum distillation units ---- two kinds of technology. Drum drying means adopting Rotary Drying Equipment for drying to reduce the water moisture, its products are high heat value quality coal; Drum drying distillation technology refers to using rotary drum dryer and rotary distillation machine together, the dryer dehydration and heat of coal, dry distillation machine dry distillation of lignite removal volatile part and the internal moisture, the product is high heat value, low sulfur, low water moisture, low volatile of dry distillation upgrade coal.

The burning of fuel, as well as the residence time of solids depends on the gas flow rate. The calculated gas time varies according to the type of project, from 1.4 to 1.7 seconds in a calciner system with tertiary air flow up to 4 to 5 seconds in total or hybrid flow systems.
Some calciner projects induce a cyclonic or rotational movement in the gas flow inside the Calcination Equipment, giving the solids a significantly longer residence time.
That is extremely favorable so that a high degree of calcination is obtained, since most of the larger particles will be calcined. If higher calcination rates are reached during the operation, guaranteed kiln production can be exceeded.
The level of calcination will depend mainly:
1. temperature inside the calciner
2. residence time of the raw meal in the system
3. solid gas separation
4. dust circulation effect
5. kinetic behavior of raw materials

Using an AAC(Autoclaved Aerated Concrete) Block Making Machine in construction has been increasing over the years. But this is not a coincidence as concrete blocks offer multiple advantages economically, in terms of constructive performance, as well as in build quality and versatility. From the AAC Block Making Machines which are lightweight and more heat resistant to the semi-automated machines, these machines continue to evolve and the type of concrete blocks continue to improve. With the accepted notion and popularity there is now high appeal for more technologically sounded block machine models such as Automatic block making machines.

What is coal briquette?
Coal briquette is made by the Coal Briquetting Equipment which uses coal dust or coals fine as the raw material. Sometimes we add other materials like the binder or something to make the briquette as most of the coal fine is hard to form together only by briquette machine.
Why coal briquette
When we mine the coal, transport it, dry it, there comes a lot of coal dust. As matter of fact, about 20% of the coal we can get is in small particles. So, coal briquette is a good way to deal with these fine or dust as briquette has more burning value and utilization rate.

  LED Grow Lights for Plant Production
Posté par : DFDVX44 - 03-12-2021, - Forum : Présentez-vous... - Réponses (2)

LED Grow Lights for Plant Production 
Introduction
Light is the single most important variable with respect to plant growth and development and is often the most limiting factor. Therefore, the use of grow lights in commercial greenhouses is beneficial for plants and growers. The reason for using Indoor Grow Lights varies and includes increasing light levels for plant photosynthesis or altering photoperiod. The duration of light a plant perceives is photoperiod. The different lighting sources that growers can use include incandescent (INC) lamps, tungsten-halogen lamps, fluorescent lamps and high intensity discharge (HID) lamps. Light emitting diodes (LED) are fourth generation lighting sources and are an emerging technology in horticulture.

LED Advantages

  • Energy efficient

  • Easy installation

  • More durable

  • Longer lifetime (less lamp changes)

  • Low heat emission
Before choosing Cannabis Grow Lights, several factors such as costs, efficiency, total energy emissions, life expectancy, light quality, light quantity, light duration and effect on plant growth and flowering should be considered. This Fact Sheet provides information about LED Grow Lights for use in plant production.

Design and Function
The design of LEDs varies and there are three main structural types, which are lead-wire, surface mounted and high-power LED. Despite the different designs, each type is mounted on a printed circuit board; therefore, LEDs function like computer chips. Foldable Grow Lights are solid-state semiconductors and when turned on or off, the action is instant. As for life expectancy (dim to about 70 percent from initial installation), LEDs can operate up to 50,000 hours. It is not necessary to replace single diodes or lamps constantly because LEDs do not burn out. Factors such as design, materials used and heat release affect life expectancy. Another important feature of LEDs is that heat does not escape from the surface, but through a heat sink which allows for close proximity between plants and LEDs. As for consumption of energy, LEDs are more efficient and use less energy than any other traditional greenhouse lights. In addition, operating costs and carbon emissions are lowered when using LEDs.

Infrared Heat Lamps vs. LED Light Therapy Devices
Are red light therapy devices different from infrared (IR) heat lamps? Yes, a lot different, and one of the big reasons is right in the name: heat.
Infrared Lamps are designed to induce heat stress on a user. The heat is the point. The problem is that excess heat can potentially cause damage to your skin. By contrast, high-quality LED light therapy devices—like Joovv—give off very little heat, and have been found safe, effective, and free of side effects in numerous clinical trials.
Even if heat lamps could deliver clinical results similar to light therapy, the burn risks are not worth it. Beyond the heat dangers, heat lamps simply do not offer the clinically-proven wavelengths or medical-grade power output of a high-quality LED device, which we will explain in more detail throughout this article.

Heat Lamps Do not Offer Clinically-Proven Wavelengths of Light
Not all natural light is created equal; different wavelengths and colors within the light spectrum have different effects. And it is hardly a secret which wavelengths are effective for light therapy. Extensive research has shown that only a relatively narrow band of red and near infrared wavelengths impact your cells and have a significant therapeutic effect.

Poultry Heat Lamps produce a wide range of wavelengths, but as the graph below shows, the wavelength curve builds to its peak output around 1100 nm. [3]
Less than 1% of the energy from heat lamps is delivered from 600-660 nm, and only about 2% is delivered in the entire 810-880 nm range. In total, these wavelengths only represent about 3% of the total energy delivered by a heat lamp bulb. In other words, 97% of wavelengths from a heat lamp fall outside of the wavelength range known to produce the greatest health benefits.

Infrared Heat Lamps Lack Power and Effectiveness
In addition to heat lamps delivering inferior wavelengths, they do not offer medical-grade power like a high quality LED light therapy device.
The total power output—sometimes referred to as irradiance—from a device also directly impacts the time required for treatments. Lower-powered products like Swine Heat Lamps take way longer to produce benefits, if ever. Imagine filling up your water bottle from a dripping faucet—it will fill up eventually, but you will waste a lot of time in the process.

UV Lamp is a type of electromagnetic radiation that makes black-light posters glow, and is responsible for summer tans — and sunburns. However, too much exposure to UV radiation is damaging to living tissue.
Electromagnetic radiation comes from the sun and transmitted in waves or particles at different wavelengths and frequencies. This broad range of wavelengths is known as the electromagnetic (EM) spectrum. The spectrum is generally divided into seven regions in order of decreasing wavelength and increasing energy and frequency. The common designations are radio waves, microwaves, infrared (IR), visible light, ultraviolet (UV), X-rays and gamma-rays.

Ultraviolet (UV) light falls in the range of the EM spectrum between visible light and X-rays. It has frequencies of about 8 × 1014 to 3 × 1016 cycles per second, or hertz (Hz), and wavelengths of about 380 nanometers (1.5 × 10−5 inches) to about 10 nm (4 × 10−7 inches).

  Metal Powder For Real Metal Cold Castings
Posté par : DFDVX44 - 03-12-2021, - Forum : Présentez-vous... - Réponses (14)

"Cold-Casting" is a term used to describe the process of mixing metal powder with a resin and applying the mixture into a mold. The finished casting gives the appearance and weight of solid metal. The metal cold-cast process is faster and much less expensive when compared with foundry casting of molten metal.

Easy To Use
Metal powder is mixed into Colormatch® resin until the mixture is thick and creamy. The mixture is then "slush-cast" or brushed onto the mold surface until the resin cures. The gel coat is then back-filled with straight resin, resin mixed with metal powder, resin mixed with steel weights or rigid foam.

Aluminum
The mesh size of this Aluminium Powder is -200 vs. the -300 mesh for the other metal powders and gives a better cold cast effect compared with other mesh size powders that we tested. Polished castings are brighter vs. castings made using nickel/silver powder, which has more of an antique metal look.
Spherical Aluminium Powder is perfect for producing castings with antique brass finishes. Polish the surface to bring out the shine of the metal powder. Afterward, apply a shoe polish to add depth and character to your pieces.
Polish your castings to produce a realistic cast bronze piece. Allow the metal in your castings to achieve a natural patina or accelerate the process with patina solutions.
With Atomized Aluminium Powder, you can give your castings a bright, modern copper appearance great for low relief wall art. Burnish with black shoe polish and apply chemical patina for a stunning rustic look.
Castings made using nickel/silver powder can be polished to produce more of an antique metal look compared to the aluminum metal powder. When mixed with SmoothCast® ONYX plastic castings will have better heat resistance for applications where temperatures may exceed 200°F.

The two solid fuel boosters that burned for two minutes helping the U.S.’s old space shuttle fleet to reach its orbit each contained 80 tons of Non-spherical Aluminium Powder, which corresponds to 16 percent of the total weight of the solid fuel. "This idea of burning metals as a fuel sounds pretty far out there, but this is something that has been done in rockets forever," says Jeffrey Bergthorson, an aeronautics engineer at McGill University in Montreal, Canada. He and colleagues at McGill and at the European Space Agency published this week in Applied Energy a study outlining how metal powder could serve as a zero-carbon fuel to power transportation and the grid.
"Aluminum powder has long been known to be a very energetic material," says Bergthorson. But other metals such as magnesium—remember the magnesium flash light—zinc, and even lithium and silicon could do as well. "If we look at the elements available in the Earth's crust, iron is the third most abundant element, and the idea of the iron economy is that once you got this thing going, you will be recycling that iron. Initially you will need a production from ore, but at some point you would not be mining iron anymore, you would simply be recycling it back and forth, adding the iron in at the point of use," says Bergthorson.
Bergthorson and his colleagues' idea is not to use Aluminium Metal Powders as a primary energy source, but as a way to store, transport and trade it as a zero-carbon fuel. If this sounds similar to the idea of a hydrogen economy, it is. In the hydrogen economy the gas is manufactured by solar or other renewable forms of energy and then distributed as a fuel that can drive cars and other transport systems. Bergthorson proposes that instead iron powder would be distributed as a means to drive power plants, ships, locomotives and even cars.

  Nitrile vs. Latex Gloves: What’s the Difference?
Posté par : drymoisture - 25-11-2021, - Forum : Des logiciels/applications INDISPENSABLES ? - Pas de réponse

Nitrile and latex are two of the most common types of general-use disposable gloves. Choose the best material for protecting your hands.
Single-use Gloves are not an essential accessory on most days, but they can be an effective illness-preventing measure. When you should wear gloves depends on what you’re doing, according to the Centers for Disease Control and Prevention (CDC). The type of disposable gloves you wear is up to you. Gloves used as personal protective equipment (PPE) are made of many different materials; some are used in chemical laboratories, while others are best for medical workers. Nitrile and latex are two of the most common materials for general-use disposable gloves. Before deciding between nitrile vs. latex, there are a few questions to answer: What are nitrile gloves, and how do they compare to latex?

What Are Nitrile and Latex Gloves Used For?
PPE, such as a face mask, is most often used by people who work with the public, including lifeguards, first responders and healthcare providers. When it comes to nitrile vs. latex, both serve the same basic purpose. Latex and Nitrile Gloves are lightweight, stretchy hand coverings that protect the wearer from direct contact with whatever they may touch, which defends first aid and healthcare providers from bloodborne pathogens. They can also prevent foodborne illnesses and skin irritation caused by household cleaners, as well as the spread of infectious diseases.
The CDC recommends wearing PPE when caring for someone who is sick and when sanitizing and disinfecting your home. Frequently-touched surfaces like doorknobs, light switches and countertops harbor tons of germs, and the cleaning products that actually disinfect can be harsh on your skin.
While disposable gloves help keep you safe by blocking direct skin contact, they are not the most effective way to prevent getting sick. The most important protective measure is frequent and thorough hand washing. Always wash your hands with soap and water after removing gloves. The U.S. Food & Drug Administration (FDA) does not recommend reusing or washing disposable gloves or other disposable PPE — effectiveness wanes with repeated use.

Why Would Someone Choose Nitrile vs. Latex?
Although nitrile and latex gloves are incredibly common forms of PPE, there are a few reasons why you might pick one over the other. The first is whether you or anyone in your household has a latex allergy. The use of Latex Gloves can cause a rash, hives, swelling and more when used by someone with a latex sensitivity. Gloves made from “synthetic materials, such as polyvinyl chloride (PVC), nitrile, or polyurethane,” are safer for people with latex allergies, according to the FDA.
Latex gloves are popular due to their elasticity and comfort, says the Occupational Safety and Health Administration (OSHA) guide to personal protective equipment. Nitrile gloves, on the other hand, are more durable and resistant to punctures and chemicals. Overall, nitrile gloves may be the more versatile option. Whichever you choose, always stock protective gloves in your garage, shop or cleaning cupboard to keep your hands safe and sanitary.


Latex: Widely considered to be the most comfortable glove type available, offering a ‘second skin’ feeling, Rubber Gloves offer protection against water-based chemicals, biological hazards, and skin irritants. However, they generally aren’t as robust as nitrile gloves and can result in allergic reactions to latex.

  Not all valves are equal: Picking the right material for the job
Posté par : drymoisture - 25-11-2021, - Forum : Des logiciels/applications INDISPENSABLES ? - Réponses (18)

Valves come in numerous sizes and configurations and are used in thousands of applications across various industries. Likewise, there are various types of valves used in piping systems. These valves vary by operating mechanism/principle, function and design.

Most common valve types and applications

  • Ball valves: Ball Valves are quarter-turn valves that can be used for flow stoppage or flow modulation. They contain a horizontally hollowed-out sphere sitting tightly in the middle of the valve. When the valve is open, the hollow side aligns with the flow. The valve can also be placed in a partially open/closed position. Ball valves work well in high-pressure applications.

  • Butterfly valves: Butterfly valves contain a flat disk/flap that swivels sideways to allow, block or regulate flow. These valves are often used in power plants and wastewater plants as shut off or regulating valves. While they are cheaper and smaller than ball valves, they are not good for high-pressure applications.

  • Check valves: Check Valves allow the flow of media in one direction while preventing flow in the opposite direction. These valves typically have an inlet and an outlet port and operate using differential pressure. They are used to prevent reverse flow — a problematic phenomenon that can occur in piping systems, in which media flows in the wrong direction. This phenomenon can have profound implications such as problematic flow, contamination of the flowing media and damage to the piping system. There are various types of check valves, best suited to different applications.

  • Plug valves: In plug valves, cylindrical or conical plugs are used to control flow. The plug has a horizontal hole through which the media flows. To open the valve, the plug is rotated sideways to align the hole to the flow. Plug valves can commonly be found in radiators, heaters and air systems.

  • Gate valves: Gate Valves are linearly operated valves that contain barriers referred to as gates. The gates are raised and lowered to open and close the valve, respectively. Gate valves are designed to be completely open or completely closed and are not suitable for flow regulation.

  • Globe valves: Globe Valves consist of a globe-shaped disc that blocks flow by closing against an orifice. The globe is raised and lowered by an outside stem and yoke, otherwise known as OS&Y. Unlike gate valves, globe valves can be used to regulate flow as they can be partially opened and partially closed.


Gear is toothed, mechanical transmission elements used to transfer motion and power between Machine Parts, and in this article, we discuss the different types of gears available and how gears work. Operating in mated pairs, gears mesh their teeth with the teeth of another corresponding gear or toothed component which prevents slippage during the transmission process. Each gear or toothed component is attached to a machine shaft or base component, therefore when the driving gear (i.e., the gear that provides the initial rotational input) rotates along with its shaft component, the driven gear (i.e., the gear or toothed component which is impacted by the driving gear and exhibits the final output) rotates or translates its shaft component. Depending on the design and construction of the gear pair, the transference of motion between the driving shaft and the driven shaft can result in a change of the direction of rotation or movement. Additionally, if the Gears are not of equal sizes, the machine or system experiences a mechanical advantage which allows for a change in the output speed and torque (i.e., the force which causes an object to rotate).

The North American forging industry continues to grow in technical prowess. OEMs are realizing that nothing beats forgings for strength and reliability. Advances in forging technology have expanded the range of shapes, sizes, and properties available in forged products to meet an increasing variety of design and performance requirements. Forging Components are regularly specified where strength, reliability, economy, and resistance to shock and fatigue are vital considerations. Forged materials offer the desired degree of high or low temperature performance, ductility, hardness, and machinability.

  What’s the Difference Between Bearings?
Posté par : drymoisture - 25-11-2021, - Forum : Des logiciels/applications INDISPENSABLES ? - Pas de réponse

Bearings are used to help reduce friction. Metal-upon-metal contact produces large amounts of friction. The friction adds to wear and tear of the metal, producing grinding that slowly degrades the metal. High Temperature Bearing reduces friction by having the two surfaces roll over each other, reducing the amount of friction produced. They consist of a smooth metal ball or roller that rolls against a smooth inner and outer metal surface. The rollers or balls take the load, allowing the device to spin.
The load acted upon a bearing is either a radial or thrust load. Depending on the location of the bearing in the mechanism, it can see all of a radial or thrust load or a combination of both. For example, the bearing in the wheel of your car supports a radial and a thrust load. The weight of the car on the bearing produces a radial load while the thrust load is produced as the car turns a corner. Here we will examine some types of common Agricultural Bearings.

Ball Bearings
Ball Bearings are the most common type of bearing and can handle both radial and thrust loads. Ball bearings are also known as deep-groove single-row or Conrad bearings. The inner ring is typically fastened to the rotating shaft and the groove on the outer diameter provides a circular ball raceway. The outer ring is mounted onto the bearing housing. The ball bearings are housed in a race and when the load is applied, it is transmitted from the outer race to the ball and from the ball to the inner race. The raceway grooves have typical curvature radii of 51.5% to 53% of the ball diameter. Smaller curvature raceways can cause high rolling friction due to the tight conformity of the balls and raceways. Higher curvature raceways can shorten fatigue life from increased stress in the smaller ball-race contract area.

Thin Wall Ball Bearing, also known as Conrad bearings, are typically used in small load applications.
The contact points between the ball and the outer race is very small due to the spherical shape of the bearing. This also helps the ball spin very smoothly. Since the contact point is so small, the bearing can become overloaded at a specific point causing the ball bearing to become deformed. This will ruin the bearing. Ball bearings are typically used in applications where the load is relatively small.

Straight Roller Bearings
Straight roller or cylindrical bearings run in cylindrical raceways and have low-friction, high-radial load capacity, and high speed capability. Roller bearings are cylinder-shaped bearings where the point of contact between the bearing and the race is a line rather than a point. Load is distributed over a larger area and allows the bearing to handle a greater load. To minimize its tendency to skew, the roller’s length is not much greater than the diameter of the roller.


Straight or Cylindrical Roller Bearings can be found in applications like conveyor-belt rollers, which are required to hold heavy radial loads.
Their usual design is free to float axially, and they have roller-guiding flanges on both sides of one ring and none on the other side. This allows for the bearing to expand due to thermal activity when used in combination with a ball bearing’s fixed location at the opposite end. A thrust load can be supported in one direction if a guiding flange is added on one of the opposing rings’ side. A second flange can be added for two-directional thrust capacity.

Needle Roller Bearings
Needle Bearings use elongated cylindrical rolling elements with small diameters. They are used in applications where radial space is limited. The diameter to length ratio for the needles varies between 1-to-2.5 and 1-to-10. Due to their small size, they cannot be guided accurately and generate high amounts of friction. They are used at low speeds and oscillating motions as a result. Cages may be used to help guide the needles and improve retention.

Thrust Bearings
Designed to handle high thrust loads, Thrust Ball Bearings are typically found in gearsets used for car transmissions between gears or between the housing and rotating shafts. The angled teeth found in helical gears used in car transmissions produce a high thrust load that is supported by the roller-thrust bearings. Roller-thrust bearings slide within a roller-race contact to handle the surface-speed variation that comes as a result of the varying diameter across the contact zone.

Tapered Roller Bearings typically consist of two rows of barrel-shaped rollers running in two raceways. One is on the inner ring and the other is on a continuous spherical surface ground on the inner diameter of the outer ring. This allows the bearing to operate with some misalignment. Spherical rollers have barrel profiles that closely match the raceways profiles, hence making them robust and having a high load capacity. They are mounted in pairs inside the bearing housing and are faced in opposite directions. This is done so that the load can be supported in either direction.

  Double Innovation In Paper Bag Machine
Posté par : drymoisture - 25-11-2021, - Forum : Des logiciels/applications INDISPENSABLES ? - Pas de réponse

We are known for making paper bags, laminating and flexo printing machines. It has designed and developed a new Paper Bag Machine that has increased the production speed by 30% and automates the mold switching process. The machine is developed using standard technology and professional technology, has at least 8 rotating shafts, and can join up to 30 rotating shafts, depending on the customer's specifications. All the electronic systems and software of this machine are developed by us, and the products produced by this machine are far more than similar products on the market.

The consumption of plastic bags continues to decline and is being replaced by paper bags. The structure of the paper bag machine is relatively complicated. Under the current conditions, it takes a long time to change the mold. To solve these problems, we have developed a new Luxury Bag Machine, which is trusted for its engineering and expertise. This newly developed machine can provide products of various sizes and characteristics, so it can switch between different product processes several times a day. It takes quite a long time to switch molds in the process of producing different products in the machines currently in use, and the company's engineers are looking for new ways to solve this problem. With this in mind, they conducted an intensive research and development study to understand how to reduce the delay between the manufacture of different products.

Another important innovation is the increase in the production speed of the machine by approximately 30%. Similar machines on the market can produce 600-700 paper bags per minute, depending on the size of the product, and the new Food Bag Machine will increase this number to 900-1000. During the development of this technology, standard tests and professional tests were carried out. Although the same product is manufactured in Europe at 500 kg, this figure drops to 200 kg in Turkey because this is a demand trend that manufacturers must comply with. If we take the daily production capacity of a machine as 1 ton, assuming that 4 different products are produced in one day, it will take an average of 4 product changes. When the switching time of each product is about 30 minutes, this means that nearly 2 hours are used to change the machine settings every day. This is a long time.

Printing Machine is a complex piece of high-precision industrial equipment that is designed to produce printed material at a high rate of speed and low cost per page. Printing presses are commercially available which use several different types of printing technologies, but the most common type is called offset lithography. These presses are commonly designed in either sheet-fed configurations, which print on individual sheets of paper or other material, or web-fed configurations, which print on long webs of paper or other material, supplied on large reels. A so-called 'full size' sheet fed offset press prints on sheets that are about 700 mm x 1000 mm in size (about 28 inches x 40 inches). "Half size" and "quarter size" offset presses are also common, and these machines print on sheets that are one-half or one-quarter as large.

Digital Cutting Machines have caught the attention of hobbyists of all sorts including scrapbookers, cookie makers, cake decorators, metal clay and polymer clay artists, and even leather workers.
With so many cutting machines on the market how do you pick the right one? I have all the cutters mentioned here and have spent a month this experimenting with each of them. In order to determine which machine is best for you, first think through what kind of projects you’d like to make? Each machine its own parameters of what’s possible so its important to know what you’ll be using it for.
To start, are you doing this as a hobby or hoping to start a small business? I’ve always believed in buying new equipment that could grow with my ideas. I went shopping for a sewing machine a few years ago and settled on a floor model that had a reduced price. It came with a lot more bells and whistles then I needed or knew how to use at the time, but after a few classes, the creative possibilities with the machine and attachments were really exciting. I feel the same way about digital cutters.

This is our fully automatic paper Handle Making Machines Set with handle loops online. This machine is used for the production of heavy duty paper shopping bags. The heavier grade paper can be printed or coated in advance for very high quality and very strong paper bags. It uses roll fed paper as stock material, the weight of the paper can be adjusted to suit your requirements. These types of paper bag making machinery are used to make paper shopping bags for food, garments, shoes, SOS, etc. The high speed paper bag making machine can be used to manufacture paper bags with handles, with the loop handle inline or online from rope for department store bags, fashion bags, kraft shopping bags, grocery brown paper bags, bread bags and so on.

Posté par : drymoisture - 25-11-2021, - Forum : Des logiciels/applications INDISPENSABLES ? - Pas de réponse

Depending on the type of food being packed, packing comes in various types. To pack these food materials, various Multi-Lane Packing Machines are used. The packing styles also change depending on the storage life of the product.
Food that are high perishable like fresh processed meats and frozen items are best when vacuum packed since it can tremendously extend its storage life. There is a separate type of Stick Bag Packing Machine or food packing equipment used to perform vacuum packaging of the products.
Here are the various types of food packaging machines:

Food Vacuum Packaging Machine:
It is one of the most efficient Horizontal Doypack Packing Machine to pack foods because it avoids air making food remain fresh. As aerobic microorganisms are responsible in swift deterioration of foods, they hardly thrive or are immobilized under this condition.
Food vacuum packaging machine helps to extend storage life of food products thereby making the product well suited for sale on the freezer or cold display storage units of several retail stores.

Biscuit Packaging Machine
Biscuit packaging machine is another type of food packaging equipment. It is usually fitted with electronic digital temperature controller to maintain high precision in achieving the desired temperature during food packing process.
It helps to bring the optimum freshness of the food. The most interesting aspect of this Stand Up Pouch Machine is that packaged products are closely monitored with its automatic feed counter that shows the quantity of items placed packed by the machine. This makes it easier for the food manufacturing companies to monitor daily factory output.

Bundling Food Packaging Equipment
Bundling Food packaging Equipment is quite common and is widely used by many food suppliers. It is capable of storing huge quantity of foods before they are banded or wrapped together as a single bundle.
It is also called as the Spout Pouch Packing Machine. It can also be used for packing small items such as stick candies or individually packed hot-dogs that need to be bundled together for economic purposes.

Bagging Machine
It is popular in several China food processing factories. Foods in this case are packed in bags, sacks and pouches. This bagging machine is common to pack cereals and powdered foods such as milk powder and sugar.

Closing Machines
These closing Irregular Doypack Machines are similarly common in many food factories. This equipment is used to tie metal wires to enclose the food bag or pouch.

Capping Machines
Capping machines are popular among food suppliers of food syrups and drinks. This equipment is not used solely to pack food items but it is usually used in conjunction with other food packaging equipment.
The major function of this equipment is to close bottled food items by placing air-tight caps. This is common in soda-manufacturing companies.

Accumulation machinery
Accumulation machinery is used along with the capping machine. This Premade Pouch Packing Machine allows proper alignment of bottles for systematic and organized filling of foods. It is used in soda companies and bottled-water companies.
There are various types of food packaging machines. It is important to tailor-fit the selection when yo buy one of these machineries according to the type of food that is being packaged to ensure optimum quality products with fully extended storage life.

When looking to price a Vertical Packing Machine, You may experience sticker shock. There are a few items you will need to consider when taking the price of these machines into consideration. Here are the items that will affect the cost of your chosen equipment.

  • Functionality - A food packaging machine could cost you anywhere between $10,900 - $65,000. The functionality of each machine has a big effect on the cost of the equipment. The price of your machine is going to be based upon the equipment's capabilities, factoring in things like speed, the hourly volume of packages produced, and whether the Horizontal Flat Pouch Packing Machine is a manual or automatic model.

  • Mechanical Components - Manual models will have less moving parts, internal computer-controlled motors and other more complicated components. As such, automatic models that can be programmed and run automatically via the control panel will cost more than the manual models available.

  • Capabilities - Depending on the model you choose and the machine's capabilities, you will have to consider your cost of materials. Entry-level machines are going to package less volume and use less materials daily versus a high-end automatic Single Lane Stick Bag Packing Machine. While a high-end automatic model will cost a lot more upfront, running higher amounts of materials will help you cut costs as you will generally get discounts on materials orders for larger volumes of product purchased. In this respect, your total cost of ownership over time will be less for more expensive higher-end models.

Bonjour, pour la création d'un site web CV, à votre avis, vaut-il mieux en mettre plein la vue au niveau du design, quitte à ce que l'UX perde un peu de sa qualité ? Ou vaut-il mieux avoir un site très fonctionnel mais pas forcément très beau ? (Pour chercher un job dans le webmarketing, après)
