Apron Feeder is a kind of continuous material conveying machinery, mainly used for primary crushing and feeding of raw ore. It is a general fixed feeder that continuously and evenly distributes or transfers various loose materials from storage bin to crusher, conveyor or other working machine along horizontal or vertical line segments.
Medium-sized Apron Feeder can be used to transport various block or loose materials from storage to crusher, conveyor or other working machinery along horizontal or inclined directions.
Medium-sized Apron Feeder uses variable frequency speed regulating motor and hard tooth surface gear reducer direct connection reduction transmission, which simplifies the structure and improves the transmission efficiency. The variable frequency speed regulating device can realize the stable adjustment of feeding amount. The power configuration and constant torque output adapt to the working conditions of load lifting and variable incoming materials, so that the supporting equipment can receive materials evenly and work smoothly, which is conducive to the realization of system automation and meets the needs of different production requirements in a large range.
Apron Feeder, low operating power, light weight; large feeding volume, low noise; stable feeding, adjustable; many common parts, easy maintenance; high efficiency and energy saving, low energy consumption; explosion-proof safety, environmental protection.
Apron Feeder Structure And Working Principle
Structure
- The Apron Feeder consists of a silo interface, a guide trough, a gate device, a transmission plate device (chain plate chain), a drive motor, a drive sprocket group, a chassis and other parts. The components are connected and assembled with bolts, and can be split and integrated, suitable for ground or underground.
- The guide trough is installed at the bottom of the silo, and the drive sprocket group is installed on the chassis by a chain, a sprocket, a bearing seat, a motor and its reducer. The manual flat gate device can realize the opening and closing of the discharge port or the adjustment of the size of the discharge.
- The return sprocket end of the drive sprocket is equipped with a tensioning device for tensioning and adjusting the parallel operation of the chain and chain plate.
- The frame at the bottom of both sides is fixed with a downward slide to play a supporting role when the transmission plate returns.
Working Principle
When the material falls from the silo into the guide trough to the transmission platform, the drive sprocket is started by the motor and driven by the sprocket to drive the chain, which is connected to the chain plate. The chain plate runs smoothly to export the material and complete the material feeding process. The feeding amount and efficiency (speed) can be achieved by the gate opening size and the speed regulation of the variable frequency motor. The gap between the inner side of the guide trough and the sprocket and chain plate is blocked by the lower sealing plates on both sides if there is leakage.
Conclusion
Apron Feeder is a quantitative feeding device for a continuous conveying system of bulk materials. It is generally divided into three types: heavy-duty Apron Feeder, medium-duty Apron Feeder and light-duty Apron Feeder. Apron Feeder are widely used in building materials, metallurgy, mining and other industries, and are indispensable equipment in raw material processing or continuous production.
