Drive Sprocket For Apron Feeder
Apron Feeders are designed and manufactured to handle heavy, lumpy and abrasive materials. Its main function is to prevent surge loads to primary crushers, belt conveyors and other equipment. Apron Feeder consists of drive wheel device, tail wheel tension device,pan- chain device and transmission device. After the head sprocket is driven, the traction chain in the pan- chain device meshes with the sprocket to drive the entire pans to move along the longitudinal center-line and the roller travels along the track fixed on the frame, thereby completing work.
Description
Drive Sprocket for Apron Feeder
Apron Feeders are engineered for heavy-duty operation and for primary or subsequent application stages. These custom-built machines are designed to suit individual requirements of capacity, size and material handled. Our apron feeder also has an integral matching scraper conveyor with built-in drive to handle spillage. This system ensures an economic layout and increased belt conveyor length vis-à-vis a conventional system with spillage chute. The feeders are specially designed to minimize maintenance.
Impact loads are absorbed by pans of rolled alloy/ cast alloy/ manganese steel material depending on application and are similar to heavy-duty track-type undercarriage shoes.
Pans are bolted to forged link chains supported on heavy-duty lifetime lubricated rollers.
High strength pans resist abrasion and withstand heavy impact loads.
Short pitch and precision-machined chain provides noise-free discharge of material with negligible impact on receiver.
Chain and roller flanges maintain rigid alignment of pans in relation to skirt.

Sprocket design features three cast manganese alloy steel segments that allow replacement of one segment at a time, without needing to dismantle the feeder or remove the chain, pans, skirts and material on the feeder.
Rather than taking multiple shifts to change out the drive sprockets, the upgraded design allows a changeout in just hours. In addition, a half-tooth design with an odd number of teeth is used to allow contact with the chain during every second revolution, which doubles the life of the sprockets.
