The heavy duty apron feeder provided by our company adopts the mining tank chain as the traction component, which can continuously transport materials in the hopper, and can be fully competent for the working environment of the system.
Designed to withstand heavy load shocks and severe material wear, the heavy apron feeder operates directly below the unloading point. This design feature enables continuous operation without shutdown failures, allowing heavy start-up with minimal maintenance.
The main structure of the heavy apron feeder is the heavy chain and support wheel installed directly on the main frame of the feeder. The type of chain and sprocket depends on the load and the different industry. The chain and pulley are D4, D7, D9, D11 traction chains produced by Carter, Komatsu and other brands or well-known domestic manufacturers. The length of the apron feeder is the center distance from the tail sprocket to the head sprocket, and the length is determined according to the needs of the customer. A drive device located at the head, the speed of which can usually be adjusted to control the feed rate of the material. The groove plates fixed on the chain are welded structural steel with special section design. The groove plates and groove plates are bonded to avoid material leakage between the brackets. The groove plates are fixed with anti-wear countersunk bolts and the chain. It is particularly important to eliminate the impact load energy. The impact load is first absorbed by the support plate and causes the elastic deformation of the slot plate. Then the impact load is transferred to the main frame structure through the slot plate and absorbed by the main frame structure. 1.apron feeder main structure, working principle and main performance
1.1 Apron feeder main structure
Apron feeder mainly has driving device, transmission sprocket, reversing sprocket, traction chain, trough plate, support wheel, frame and other groups
Agreed.
1.2 How apron feeder works
The material in the bin enters the guide trough through the connecting section and falls on the pallet. When the pallet is stationary, the material finally stops moving by the internal friction force and forms a static accumulation at a certain Angle at the discharge port. When the drive sprocket starts to rotate under the external power, it drives the traction chain movement, the traction chain drives the movement of the pallet, and the pallet drives the material on it to the discharge port. The running pallet turns to the return after discharging at the discharge port, and the material is continuously discharged from the discharge port, thus completing the feeding and loading process; The main load is supported by the rolling wheel, the operation resistance is small, the driving power required by the equipment is small, and the working life of the system components is long. Change the feed rate,
Through the optional frequency converter, the motor speed can be changed to change the feed amount.
1.3 Apron feeder Main structural performance
1.3.1 Trough plate bracket
The groove plate structure is designed as a single arc overlapping, which is tight and has good leak-proof performance. The groove plate material is not less than 40Mn2, the thickness is not less than 25mm, the whole processing process adopts fixed mold docking, welding, heat treatment, machining and other pipelin-type seamless production line, with high processing accuracy, long service life, simple installation, easy to replace and so on.
