chute feeder, manufacturer of chute feeder - xinhai

The machine is usually installed underneath the discharging opening of the ore bin. Minerals fall on the bushing. The bushing is located at the chute bottom, configured on the idler wheel, and via an eccentric device connected with a reducer which is linked to an electric motor by a coupler. When it works, the electric motor drives a reducer via a coupler; eccentric disk and drain cap which is situated between the chute frame bottom and roller begins to do reciprocal and linear motion to uniformly feed minerals.

ross chain feeders

A feeder that uses chains to regulate the ore flow in a different manner is the ROSS Chain FEEDER. This feeder uses a series of very large, heavy chain that has been forged into loops. These loops are placed over cogged wheels that are suspended over the ore passage. The free end of the chain loops are hung down onto the rock. The size and the weight of the chain links are sufficient to stop the flow of ore. To keep the ore moving the chains are revolved, dragging the links over the ore will cause it to flow.

A problem common to all (even chain) feeders is the ore size, large ore tends to jam together in what is known as a HANG UP. It is called this because it is usually up an ore pass above the equipment, and is just hanging there. To free it often means that the operator will have to either pry it down with a scaling bar or in severe cases it will have to be blasted. Both of these procedures have a certain degree of danger involved. No one should attempt either one without the necessary instruction.

Large ore poses another problem that is unique to the feeders that use chains for a control. Once the ore reaches a critical size it begins to hang up easier, when it does the open area that is created directly below the hang up allows the rock that formed the hang up to gain velocity when it comes down. The speed of these falling rocks can be great enough to push the chains out of the way allowing more ore than can be handled through. Very fine ore can present a similar problem, not only to the Ross feeder but many of the other types of coarse ore feeders as well. What happens is the smaller rock will flow unhampered, around, through or over the feeder. Unable to stop the flow, the conveyors or the crushers that the ore is being fed to, will become over loaded. To control both of these problems, a secondary form of regulating the tonnage may have to be resorted to. This could be a simple sliding gate placed after the original feeder. Or as in many cases, more than one feeder, this allows the operator to shut one down should it RUNAWAY. If runaways are a problem, provisions will be made in the operating procedure to handle them. Multiple feeders are a method of tonnage control, as is regulating the speed that the Ross feeder chains revolve.

The Chain Feeder works on a different principle altogether from the apron feeder. It consists of a curtain of endless steel chains, suspended from and driven by an overhead tumbler, and mounted as a rule in a chute leading out of the bin, as shown in Fig. 3. The size of the bin opening and the slope of the chute must be sufficient to ensure that the ore flows down without any chance of choking or stopping. The motion of the chains as they move with the material Controls theflow of the ore with a regularity comparable with that of an apron feeder. The size of the links of which the chains are composed varies according to the size and character of the feed ; the curtain must be heavy enough to stop the most violent rush of material likely to be encountered. The Chain Feeder may be driven by its own motor, from a line shaft, or from the crusher or conveyor that it serves. Changes in the rate of flow of the ore are obtainable by the introduction of a change speed gear, which is the preferable method for large feeders, or by the use of a chute with a pivoted end, the raising of which decreases the tonnage flow, and vice versa. If such a chute is used for loading skips, trucks, etc., the flow of ore can be cut off sharply when the requiredamount has been delivered by raising the pivoted end of the chute, which action also switches off the motor driving the feeder.

Not only is the feeder cheap, but it is as simple and fool-proof as any type that is made ; it is almost impossible to damage it, and the wear on the tumbler and chains is negligible. For these reasons it is very suitable for controlling the feed from the coarse ore bin. It is also suitable for regulating the flow of such material on to a belt conveyor, since, however large the lumps, it will give a quiet feed with the minimum amount of damage to the surface of the belt.

what is an apron feeder? (with pictures)

An apron feeder is a large machine that carries materials through the parts of a manufacturing or industrial process. These machines resemble short conveyor belts, and may also be known as plate feeders or apron conveyors. Apron feeder machines allow engineers and process managers to automatically control the volume of materials that are added to a process, and regulate the rate at which these materials are added.

Manufacturers construct apron feeders from heavy, durable materials like steel. The machine must be capable of supporting large, bulky materials like rocks, which may have jagged edges. To withstand the heavy weight of these types of materials, the belt portion of the apron feeder is made from thick steel trays or pans. Chains along either end of the feeder help move the trays along the conveyor area, and are powered by an industrial motor or engine.

Apron feeder machines can be found in mining operations, factories, and concrete plants. In mining, the apron feeder carries rocks and minerals for crushing or further processing. At a factory, these machines may be used to add ingredients to a food or other mixture. Because of their heavy-duty design, apron conveyors are also a popular choice for transporting concrete and stone for crushing, recycling, or mixing.

Materials that will be carried by the apron feeder are held in a large hopper above one end of the belt. The amount of material that reaches the feeder is determined by the distance between this hopper and the top of the feeder. If the two are placed close together, only a small volume of materials can reach the belt at any given time. When the hopper is placed farther away, materials pour onto the belt more quickly to speed up the feeding process.

As the hopper deposits materials onto the apron feeder, the metal pans that make up the belt travel horizontally like a conveyor belt. When the trays reach the end of the belt, they dump, or feed the materials into another vessel. This may be a large bin, sorting machine, grinder, or any other vessel needed to complete the specified process. Workers can adjust the speed of the belt to speed up or slow down the manufacturing process as needed. Workers also can stop the belt to pause feeding and makes any required changes.

Apron feeding machines cannot be used in applications where precise feeding and measuring is required. For example, they cannot be used to mix sensitive ingredients at an exact ratio to make food, medicine, or cosmetics. They are also not designed to hold most liquids, and require modification before they can transport fluids effectively.

cattle equipment glossary of important terms | blog | arrowquip

Cattle chutes have their own set of terms, and in some cases terms can be used interchangeably as different countries refer to them with a different name or phrase. We created the ultimate glossary of terms about cattle chutes. No matter who youre talking to, we have the terms theyre using.

Alley Part of the cattle chute system that moves the cattle into and/or out of the chute safely. Alleys are adjustable to the size of cattle being worked, and into configurations that meet the needs of your facility and the job at hand.

BCS Body Condition Score You may want to assess a BCS to all or your cattle as you work them through the chute, and track any changes over time. BCS scores are a universal method for assessing the amount of fat (or lack thereof) on animals.

Bud Box Type of design in cattle handling facility that positions the handler to facilitate cattle flow into the chute, using correct cattle handling principles. A bud box has a small, rectangular design.

Calf Table Calves are tipped to the right or left while securely in the calf tipping table, and procedures can be performed efficiently, including castration, dehorning, and branding. Tables are also available for and used for trimming hooves and other procedures on full-sized cattle.

Cattle Panels - Used to create cattle handling systems that allow handlers to work with livestock efficiently. Good panels should make it easy to get out of the pen if necessary, and have wide railings that minimize bruising and challenging to keep cattle safely contained in the system.

Cattle Vet Cage Also called a palpation cage. A necessary part of a chute for those breeding heifers or cows, the vet cage is also useful for emergency procedures on animals. Gates are essential to separate the handler from the working chute.

Draft Pound - The central hub of the cattle handling system that connects all working equipment and outer pens. Simplifies sorting with gates connecting all holding pens. Allows cattle to be worked through the system again in the event of a missed catch.

Full Opening Stanchion The head gate is two separate pieces that slide open and closed similar to sliding doors. Straight and curved bar models are available; animals walk through after completing procedure.

Head Holder Added to a cattle chute to hold the animals head in place in a more comfortable and relaxed position for the cattle. Used instead of a stanchion, guillotine, or other type of head gate. The head holder has a scissor style clamp and a locking mechanism. This is a new product for cattle chutes only available from Arrowquip.

Holding Pen An essential part of your cattle operation, the holding pen is the area animals are kept in prior to being worked through the cattle chutes. It should hold the maximum number of animals you would work at one time. The term holding pen is used interchangeably in some cases with the terms cattle tub, corral, and crowding pen. Ideally your cattle will move from a holding pen into your cattle chute system, decreasing stress and maintaining a safe environment for cattle and handlers.

Hydraulic Cattle Chute/Crush A hydraulic chute or crush can be worked from any point on the side of the chute, allowing ranchers to work from the front, side, or back, while staying out of the flight zone of their cattle.

Loading Chute Loading chutes are specifically designed to load cattle onto a trailer quickly, before those that entered the trailer first decide to come back out. Different types of trailers require different size loading chutes. You also need to make sure that the pen holds up to the largest load of cattle you will take in one load.

Manual Head Gate A manual head gate on the front of your chute needs to be operated by a handler. Higher quality chutes will have an adjustable handle, meaning the head gate can be operated anywhere along the side of the chute.

Needle Door/Access The needle door is located on the chute, in the neck and shoulder region of the cattle, allowing easy access for procedures such as vaccination and branding. At Arrowquip, we engineered our needle door so that the panel can be removed for better access.

Palpation Gate Part of a commercial squeeze chute, or in addition to the head gate. The palpation gate is used when conducting artificial insemination, castration, and other procedures on cattle in conjunction with the palpation cage or cattle vet cage.

Scales Used for weighing cattle, calves, grain, feed or other items. Placement varies depending on the operation, although they can be placed near the chute or head gate for data collection while working with the cattle. Types of scales available for cattle include crates, platforms, and plates.

understanding conveyor systems - types, applications and considerations

Conveyor Systems are mechanical devices or assemblies that transport material with minimal effort. While there are many different kinds of conveyor systems, they usually consist of a frame that supports either rollers, wheels, or a belt, upon which materials move from one place to another.They may be powered by a motor, by gravity, or manually. These material handling systems come in many different varieties to suit the different products or materials that need to be transported.

Belt conveyors are typically rated in terms of belt speed in ft/min. while powered roller conveyors described the linear velocity in similar units to a package, carton, etc. moving over the powered rollers. Rated speed applies to apron/slat conveyors and drag/chain/tow conveyors as well.

Throughput measures the capacity of conveyors that handle powdered materials and similar bulk products. It is often given as a volume per unit time, for instance, as cubic feet per minute. This attribute applies to bucket, pneumatic/vacuum, screw, vibrating, and walking beam conveyors.

Drives can be located in different places on conveyor systems. A head or end drive is found on the discharge side of the conveyor and is the most common type. Center drives are not always at the actual center of the conveyor, but somewhere along its length, and are mounted underneath the system. Theyre used for reversing the direction of a conveyor.

Belt Conveyors are material handling systems that use continuous belts to convey products or material. The belt is extended in an endless loop between two end-pulleys. Usually, one or both ends have a roll underneath. The conveyor belting is supported by either a metal slider pan for light loads where no friction would be applied to the belt to cause drag or on rollers. Power is provided by motors that use either variable or constant speed reduction gears.

The belts themselves can be made from numerous materials, which should correspond to the conditions under which the belt will be operating. Common conveyor belting materials include rubber, plastic, leather, fabric, and metal. Transporting a heavier load means a thicker and stronger construction of conveyor belting material is required. Belt conveyors are typically powered and can be operated at various speeds depending on the throughput required. The conveyors can be operated horizontally or can be inclined as well. Belt conveyors can be troughed for bulk or large materials.

Roller Conveyors use parallel rollers mounted in frames to convey product either by gravity or manually. Key specifications include the roller diameter and axle center dimensions. Roller conveyors are used primarily in material handling applications such as on loading docks, for baggage handling, or on assembly lines among many others. The rollers are not powered and use gravity, if inclined, to move the product, or manually if mounted horizontally. The conveyors can be straight or curved depending on the application and available floor space.

Powered Roller Conveyors use powered rollers mounted in frames to convey products. Key specifications include the drive type, roller diameter and material, and the axle center dimension. Powered roller conveyors are used primarily in material handling applications that require the powered conveyance of the product. Various drive types include belts, chains/sprockets, and motorized rollers. Some of the uses of powered roller conveyors are food handling, steelmaking and, packaging.

Apron/Slat Conveyors use slats or plates made of steel, wood, or other materials typically mounted on roller chains to convey product. The slats are not interlocked or overlapping. Apron/slat conveyors are used primarily in material handling applications for moving large, heavy objects including crates, drums, or pallets in heavy-industry settings such as foundries and steel mills. The use of slats in heavy duty use cases prolongs the service life of the conveyor over other conveyor types that employ belts, which would wear out quicker under the exposure to heavy loads. These conveyor systems are usually powered and come in many sizes and load capacities.

Ball Transfer tables or conveyors use a series of mounted ball casters to allow for unpowered, multi-directional conveyance of the product. Key specifications include the ball material and size. Ball transfer conveyors are used in material handling applications such as assembly lines and packaging lines, among others. When positioned where multiple conveyor lines meet, they are used to transfer products from one line to another and are often used in sorting systems. Many sizes and load carrying capacities are available. Ball transfer conveyors are not powered and rely on external forces to move the product along the conveyor.

Magnetic Conveyors use moving magnets mounted beneath stationary plates, tables, or other kinds of non-magnetic slider beds, to move magnetic (ferrous) materials, often in the form of machining scrap. Magnetic conveyors are commonly used as chip conveyors to remove ferrous chips from machining centers. Systems can be configured to use horizontal motion, vertical motion, or combinations. They can be beltless or may use a conveying belt instead of a slider bed. Underneath the conveying belt, a rail containing an electromagnet is used to attract ferrous materials to the belt. Because of the magnetic attraction of the product to the conveyor, these systems can also be used upside down.

Bucket Conveyors or bucket elevators use multi-sided containers attached to cables, belts, or chains to convey products or materials. The containers remain upright along the system and are tipped to release material. Bucket conveyors are used in applications such as parts, bulk material, or food processing and handling. The conveyed material can be in liquid form or dry such as sludge, sand, manure, sugar, and grain. The systems can be used horizontally or can be inclined or vertical to change levels of the delivered products. Many sizes and load carrying capacities are available depending on the application.

Chute or Trough Conveyors are material handling systems that use gravity to convey product along smooth surfaces from one level to another. Key specifications include the chute material and the physical dimensions such as length and chute width. Chute conveyors are used for scrap handling, packaging, postal service package or mail handling, etc. Chutes are designed to have a low coefficient of dynamic friction, allowing the product or material to slide easily, and can be straight or curved depending on the needs of the application.

Drag/Chain/Tow Conveyors use mechanical devices attached to moving members, usually chains or cables, to drag or tow products. Drag conveyors are used for moving bulk materials in bins, flights, or other attachments and can have multiple discharge or loading points. Tubular drag conveyors use a fully enclosed system of chains to convey product in any direction. Chain conveyors use a chain, or multiple chains to move pallets or other hard-to-convey products. Tow conveyors use a towline such as cables or chains, usually in the floor or just above it, to tow product directly or to tow wheeled carts or dollies.

Overhead Conveyors are mounted from ceilings that use trolleys or carriers moved by chains, cables, or similar connections. Overhead conveyors are primarily used in material handling applications where the product needs to be hung, such as dry-cleaning garment lines, paint lines, or parts handling systems, or for cooling and curing. Various types of overhead conveyor systems configurations are available including electric track, monorail, trolley, as well as inclined or ramped. Depending on the application, the load-carrying capacity may be critical. Most overhead conveyors systems are powered and controlled, while others are hand-operated conveyor belts.

Pneumatic/Vacuum Conveyors use air pressure or vacuum to transport materials or items in or through closed tubes or ducts or along surfaces. Pneumatic/vacuum conveyors are used primarily in materials handling applications such as dust collection, paper handling, ticket delivery, etc. and in processes such as chemical, mineral, scrap, and food. Materials for the conveyors can be metallic or non-metallic depending on the media being conveyed. Various sizes are available depending on the load and throughput requirements.

Screw conveyors, sometimes known as spiral, worm, or auger conveyors use helical elements to move materials. They consist of a helical screw element or steel auger that rotates around a central shaft, driving the work material according to the screw design and rotational direction. The helical screw functions within a casing, trough or compartment to take full advantage of the rotational force. Manufacturers use screw conveyors to transport materials such as flakes, grains, powders, seeds, and granules. Alternatively, these devices can be used to mix, agitate or blend such materials, or to maintain solutions. They are used widely in agricultural applications, from use in farm machinery like threshers and balers to factory-based grain and crop movers. A mini screw conveyor can also transport wet, non-flowing and caking materials that might otherwise be difficult to move, such as concrete. Other applications for screw conveyors are the conveying of various mechanical parts or to function as a bottling system conveyor. The screw can be of a paddle or ribbon design depending on the application and can be driven via a chain and sprocket, gears, or direct drive.

Types of screw conveyors include bottom conveyors and centerless screw conveyors. Bottom conveyors use multiple screws in an open trough. Centerless, or shaftless, screw conveyors do not contain a central shaft and instead consist of an empty helix. This design still moves the substrate but allows for more freedom within the casing. Materials can be metal or non-metal depending on the media being conveyed.

Vertical Conveyors move products vertically between levels of conveying lines. Key specifications include the lift speed and maximum load height. Vertical conveyors move material or product to higher levels within a facility. They are further classified as continuous lifting or reciprocating. Various sizes and load capabilities are available depending on the application.

Vibrating Conveyors use rotary or linear vibration to move material along their system beds. Vibrating conveyors are used for moving dry, bulk materials such as aggregate, gravel, coal, etc. The bed of the conveyor vibrates to move the material along its length. The conveyor can be a trough, a tube, or a flat table top. Many sizes are available depending on the application.

Walking Beam Conveyors use a combination of static supports and moving supports to index workpieces through manufacturing cells. Walking beam conveyors are used on automation and assembly lines, where items need to be placed in specific locations in a sequential manner. The item being supported at a stationary position is picked up by the walking beam and indexed to its next position, where another manufacturing step takes place. This movement repeats over the length of the conveyor. Walking beam conveyors can have single or multiple lines depending on the product.

Wheel Conveyors use unpowered wheels to move objects along their lengths by gravity or manual power. Wheel conveyors are used for item or package handling and are commonly employed for loading and unloading trucks and moving packages, pallets, etc. through facilities or along assembly lines. The conveyors are configured by the number of wheels and wheel spacing, depending on the load requirements and the application.

When deciding on which conveyor system best suits your needs, a key consideration is the material is being transported. Some important characteristics to consider are size, flowability, abrasiveness, corrosiveness, moisture content, and the temperature at which it must be kept. The composition of the material, if powders, granules, pellets, fibers, or flakes are being conveyed, should also be considered, along with the particle size, weight, and density.

The function of the conveyor system itself may vary. The two main categories of moving material through a process are conveying and feeding. Conveying is the moving of materials from one or more pickup points to one or more drop points. The desired window of time for this movement should be considered, as well as the amount of pickup and drop points, the amount of material being moved, and whether or not cross-contamination between multiple materials is a concern.

Feeding is more time sensitive and requires more precise systems than coveying. Material is usually moved from one pickup point to one drop point. The product being moved may have to be delivered in batches, or at a controlled, continuous rate.

An essential factor to consider before the selection of a conveyor system is the environment in which it will be used. High humidity, temperature, vibration, pressure, fragile or hazardous materials, and flammable products in the facility should all be discussed with a conveyor manufacturer to determine any potential risks and the countermeasures and workarounds needed. The size of the system compared to how much room in the workspace is available should be considered, along with how it will fit alongside existing equipment.

Conveyors systems are often relatively complex in their design and construction owing to their large scales and integration into different factory processes. Still, the modular nature of many conveyor components makes even long and complex systems readily achievable. Manufacturers of such systems can offer design assistance so that the conveyor suits the workspace.

Cleats, high friction belting, buckets, etc. are common forms of preventing product slip. A heavily loaded inclined belt conveyor can slip backward when the drive is off. Such conveyors employ backstopping brakes that engage automatically with de-energization of their motors. Often, the brake is releasable to allow the conveyor to reverse for unloading prior to servicing. In some conveyors, a certain amount of slippage is desirable; those handling glass bottles on packaging lines will often employ some form of back-pressure relief to prevent breakage to the bottles as they accumulate in a staging area such as a filler infeed.

A conveyor belt is susceptible to static electricity as the belt is continuously pulled against the end pulleys. If electrical components are being conveyed, static electricity can be hazardous. Anti-static conveyor belt measures such as conductive belts or static control brushes should be considered to protect products.

Other safety considerations must be exercised due to often long conveyor lengths and their proximity to personnel. Live roller conveyors can be furnished with pop-out rollers that disengage from their drive belts if a persons hand or foot slips between rollers. Crossovers can be used to permit people to pass over long sections of belt conveyors. Roller style conveyors often use manual or powered gate sections to accomplish this.

Conveyors often incorporate some type of soft starter or clutch mechanism to avoid overloading motors when starting fully loaded belts, chains, etc. Some belt conveyors are fitted with geared motor drives that incorporate internal motors and gear drives within the head rollers which eliminate the need for externally mounted motors and power transmission components.

While many conveyor systems are fixed and permanent, a great many are also portable and designed for loading trucks, railcars, silos, etc. Outfeed and infeed conveyors built specifically for packaging operations are often caster-mounted for easy transport within a facility.

Conveyor selection depends on product type, throughput or speed, elevation change, and in some cases, industry focus. Belt conveyors, for instance, come in a variety of sizes and can range from foot-long units used on packaging lines to mile-long systems used for mining operations. Conveyors can be hand poweredwhere products are moved along manually over rollers or wheelsor engine/motor powered, or gravity powered. In general, though, they are driven by AC and DC motors, either directly or through reduction gears, chains, and sprockets, etc. Products generally ride on the top surfaces of conveyors, though exceptions exist.

Overhead conveyors, as found at dry cleaners, slaughterhouses, or wherever floor space is a concern, suspend their loads from trollies which ride along overhead tracks. Other conveyors, such as screw and pneumatic types, convey their products through semi-enclosed troughs or tubes. These conveyors often handle dry products and powders. Some conveyors are designed to move products precisely between manufacturing operations. Walking beam conveyors are an example of this type. Other conveyors transport hard to handle products, such as cosmetic bottles, through fillers, labelers, and other processes by holding each container in individual pucks or pallets.

Conveyors are sometimes custom designed from modular components such as straightaways, curves, transitions, merges, dividers, etc. Manufacturers of such components often provide design expertise and installation assistance. Other conveyors are stand-alone systems, complete with drives and controls. Manual type roller and wheel conveyors can commonly be purchased in discrete sections and bolted up to form material handling systems of nearly any length. In general, powered conveyors employ head shafts and tail shafts where the head end provides the drive arrangement, and the tail end provides for adjustment of the chain or belt tension.

Conveyor Controls can be simple on/off varieties, slightly more sophisticated soft-start types which cushion loads upon startup, or variable frequency drives that can control the speed, acceleration, etc. of ac motors. Very long belt conveyors transporting ore and other products often rely on conveyor belt idlers to form troughs in the belts to better contain the conveyed materials.

feeder machine types | how to choose a feeder equipment | m&c

Feeder machine is a kind of feeding equipment which can feed bulk and granular materials from the stock bin to the receiving devices evenly, regularly and continuously. Which has been widely used in cement, mining, metallurgy, coal, chemical industry, ceramics, grain, electric power and other industrial and mining enterprises.

Feeder machine is the most ideal equipment to realize production automation. The feeder machines can not only be used with electronic scales or microcomputers, but also can work alone for feeding. The common types of feeder machine are as follows:

When vibrating feeder is working, the vibrating motor drives the eccentric shaft or eccentric block to drive, and the centrifugal force produced by the rotation of the eccentric block is used to make the screen box and vibrator move in a continuous circle or approximate circle, and the bulk and granular materials from stock bin are fed into the receiving device uniformly, regularly and continuously .

Vibrating feeder is widely used in crushing and screening equipment of coal mine, mineral processing, chemical industry and mills etc. Usually suspended under the stock bin by a spring, the feeder trough can be arranged horizontally or with an angle of no more than 10.

Belt feeder is the same as that of belt conveyor in structure, but the roller space of belt feeder is smaller to bear the pressure of materials in the silo. Guide baffles are arranged on both sides of the conveyor belt to prevent spreading. The belt speed < 0.5 m/min. The feed rate can be adjusted by changing the belt speed or the height of the outlet baffle.

Belt feeder has the advantages of large bearing capacity and short length, so it is also a kind of economical feeding equipment. The feed ore size suitable for belt feeder is less than 350mm and the belt speed is below 0.3m/s generally. Belt feeder is mainly used in ore buffer bin discharge after coarse crushing, ore feeding of medium/fine crushers or screening equipment, discharge of powder bin.

Plate feeder is suitable for short distance transportation and can bear heavy working load, including 3 types: heavy, medium and light. The maximum ore size of heavy plate feeder can reach more than 1000mm. The plate feeder is mainly used for coarse crushing ore feeding, ore buffer bin drainage after coarse crushing, and coarse ore heap discharge.

Plate feeder can be installed horizontally or tilted, with a maximum upward inclination of 20. It is suitable for materials with loose density less than 1200kg/m, block weight less than 140kg and temperature below 350.

Chute feeder is suitable for the ore feeding of medium-sized materials, the maximum particle size can reach 450mm, and the ore feed can be adjusted by adjusting the eccentricity of the eccentric wheel of the transmission mechanism. The width of the trough body of the chute feeder is 2-2.5 times of the maximum particle size of the ore feed, which is mainly used for the feeding of jaw crusher and bulk lime in the preparation of lime milk.

Pendulum feeder is suitable for short distance transportation and high specific gravity materials with a particle size of 35 100mm. Pendulum feeder is not suitable for conveying dry powder materials, otherwise dust pollution and outlet blockage will occur.

Pendulum feeder is mainly used as the feeding equipment of the belt conveyor when collecting ore in the ball mill, and the feed particle size is generally less than 25mm, which belongs to intermittent feeding.

Disk feeder is a kind of continuous volume feeding equipment composed of driving device, feeder body, metering belt conveyor and metering device, which makes use of the fluidity of materials. The material is scraped from the container to the receiving equipment through a rotating disc and an adjustable scraper, which is suitable for all kinds of non-viscous and not very good fluidity -20mm fine materials.

Screw feeder can be installed in the lower part of the silo and is suitable for horizontal, vertical or inclined conveying. The material flow is controlled and adjusted uniformly and continuously by changing the spiral speed. The screw feeder is easy to feed non-viscous powdery, granular and small particle materials evenly to the receiving equipment from the silo and other storage equipment.

Screw feeder has the features of conveying, sealing, homogenizing and stirring. It is a common equipment in cement raw meal homogenization and silo sealing feeding. There are many types of screw feeder, such as solid screw, belt screw, variable pitch screw, conical screw and so on.

Impeller feeder is composed of a group of blades installed on the shaft and the outer sealing shell. Driven by the motor, the impeller on the spindle is driven by the reducer to drive the material from the upper silo through the impeller groove to feed out evenly. The feeding capacity is changed by adjusting the speed of the impeller.

Scraper feeder is composed of many scrapers fixed between two chains with a certain distance between them. The scraper moves along the slot bottom, which can be used for horizontal transportation or inclined transportation. When transporting upward along the incline, the inclination of the material layer shall not exceed 25 , and when transporting downward, the inclination shall not exceed 20 .

The working principle and traction parts are the same as the scraper conveyor. Scraper feeder can realize closed and multi-point feeding, which is suitable for materials with less powder or granule, grindability and stickiness.

Electromagnetic vibratory feeder uses the electromagnetic vibratory exciter as the vibration source to drive the hopper, which has the features of small amplitude, high frequency, slow conveying speed. Electromagnetic vibratory feeder is a new type of quantitative feeding equipment, which can meet the requirements of continuous production.

The maximum ore feeding particle size of electromagnetic vibratory feedercan reach 500mm, it is widely used for ore feeding of medium and fine crushing equipment and screening equipment, ore discharge of ore bin, etc.

spinning carding machine : chute feed system | textile study center

Card is arranged in series circuit through pneumatic pipe. Pneumatic tubes are systems that propel cylindrical containers through a network of tubes by compressed air or by partial vacuum. The blow room machinery is linked to the cards by trunking and the opened cleaned cotton is conveyed by pneumatic means to each card this is the principle of chute feed system.

1. Direct automatic feed to card increases B/R working efficiency. 2. Elimination of man power during scutcher operation. 3. Processing of rejected lap is avoided. 4.
