Working principle of Apron Feeder Conveyor
Apron conveyor is a kind of conveyor widely used in scrap steel processing plants. With its flexible layout, strong environmental adaptability, variable frequency speed regulation and low maintenance cost, it plays a core role in the electric furnace scrap preheating and continuous feeding system, and is highly praised by the electric furnace transformation in the iron and steel industry. It is an indispensable equipment in the process of raw material treatment or continuous production, especially suitable for conveying large and sharp materials.
Features
1. Easy to assemble and disassemble, easy to maintain.
2. In case of long-distance transportation, it is equipped with automatic fault alarm and emergency shutdown device.
3. When inclined conveying, a safety device can be installed to prevent the carrier from reversing.
4. The auxiliary device for cleaning the conveying trough can be installed.
5. The conveyor is capable of starting at full load. It can start and operate normally under the condition of 15% overload, and has the function of overload automatic protection.
6. Body:
(1) The body of the apron conveyor has good impact resistance, and the structure is easy to assemble and disassemble and change the installation angle.
(2) The straightness tolerance between the inner side of the roller guide rail and the upper plane is 1/1000, the deviation of the gauge is +3mm, and the tolerance of the plane on the guide rail to the installation parallelism of the head and tail bearing seat of the machine body is 1.5mm.
(3) The straightness tolerance of the main beam of the machine body is 1.5/1000, and the allowable straightness along the longitudinal direction of the machine body is 10mm.

The Structure

Driving device of Apron Feeder Conveyor: the driving components often adopt sprocket, drum wheel with socket, special claw wheel and chain crawler device with special claw shape. The function of the tensioning device is to obtain the initial tension of the traction component. In the Apron Feeder Conveyor, the initial tension must make the tension of the traction component on the winding branch of the drive sprocket enough to ensure that the traction component can be wound out of the drive sprocket correctly.
Base of Apron Feeder Conveyor: it is generally welded with angle steel or channel steel, and its head and end ends are made into separate frames for installing driving devices and tensioning devices; The middle straight-line section is generally made into a 4 ~ 6m metal structure section to support the walking part.
Base plate bearing member of Apron Feeder Conveyor: it is fixed on angle steel or parts of special structure, and the latter is fastened with traction members. The structural form of base plate depends on the physical properties of the transported goods, the conveying capacity and the placement form of the goods on the base plate, including wave type without edge, wave type with edge and deep type with edge.
Flake chain of Apron Feeder Conveyor: it is a kind of chain widely used. The inner chain is fixed on the end face of bushing with interference fit, while the outer chain is fixed on the pin shaft with lock. Therefore, when the chain is bent on the sprocket, the friction occurs between the pin shaft and the bushing, the pressure distribution surface is large, and the joint wear is small. At the same time, the chip chain is more impact resistant, reliable and stable. Its disadvantage is that it can only bend in the plane perpendicular to the plate, can not bear the bending action in other directions, and the chain joint is sensitive to dust, easy to be worn, and the cost is high. The segments of the chip chain are in pairs, so the chain effect on the conveyor is even.
Which industries or materials are Apron Feeder Conveyor suitable for?
Coal powder, crushed coal, soot, carbon black, ammonium bicarbonate, pyrite powder, ammonium chloride, copper concentrate powder, alumina powder, gypsum powder, limestone powder, soda powder, urea, activated carbon, sodium oxide, silicon Calcium acid, asbestos powder, synthetic resin, rubber powder, calcium carbide, pottery ten, synthetic fertilizer, powdered pesticide, calcium sulfate, thiamine, soda ash, powdered medicine, wheat, soybean, rice, sugar, starch, crushed charcoal, wood chips , sawdust, polyvinyl alcohol synthetic detergent, fly ash phosphate fertilizer, etc.
Materials that Apron Feeder Conveyors are not suitable for conveying:
High temperature, toxic, flammable and explosive, highly abrasive, highly corrosive, highly adhesive, highly suspending, highly fluid, hard and brittle Materials that do not want to be broken.

When choosing a slat conveyor, please note the following:
1. The slat conveyor considers its own production conditions. The applications of slat conveyors in different industries are different. For large electromechanical industries such as automobiles and home appliances, heavy-duty Apron Feeder Conveyors should be selected, and industries such as food and electronics should choose light chain conveyors.
2. The slat conveyor determines the conveying material requirements. The chain plate of the Apron Feeder Conveyor is made of polypropylene, polyethylene, acetal, nylon, stainless steel, etc.; the frame of the Apron Feeder Conveyor is composed of stainless steel, high-strength aluminum alloy, carbon steel plate bending, carbon steel channel, etc., according to Choose the appropriate sheet material for the characteristics of the material you are transporting.
3. The slat conveyor determines the conveying direction. According to the different conveying directions, the scale plate conveyor is divided into linear phosphorus plate conveyor line, climbing phosphorus plate conveyor, turning chain plate conveyor, vertical phosphorus plate conveyor, curved phosphorus plate conveyor, accumulating phosphorus plate conveyor, etc. . Select the conveying direction according to the space characteristics of the site.
4. Determine the basic parameters of the slat conveyor. The width, height, spacing, length, conveying speed and carrying capacity of the conveyor can be set according to the needs of the producer.
