Apron feeder

Apron feeder is important in ore feeding and conveying system. It is to transport ore to primary crusher for evenly and continuously feeding, and also for short-distance material delivery. It is especially appropriated for transporting materials with large proportion, large particle size, and strong abrasiveness, and can work reliably in the open air, humidity and other harsh conditions, and can be widely used in metallurgical, mining, cement, and building materials. Both horizontal and oblique installation is ok, with maximum installation angle of 25º.

Features and technology advantages of apron feeder
1. The machine has more reasonable structure, and more simple and convenient installation, disassembly, and maintenance.
2. suspension and single point floating to reduce installation error and improve the life of drive system..
3. Chain plate is in the single or double circular arc overlapping form, with impact and abrasion resistance and no leakage of materials.
Working principle of apron feeder
The driving device of apron feeder works in the way that motor drives reducer, then the cross sliding coupling & eccentric mechanism drives pawl, pawl toggling ratchet and ratchet driving the sprocket makes the feeder running. Eccentric mechanism is installed cross sliding coupling, the other end provided with the eccentric disc driving pawl and ratchet. The middle of the main driving system is equipped with two sprockets & chain mesh and drives the feeder operating. You can change the running speed of the feeder by adjusting the eccentric distance and optimal running speed can be obtained by adjustment of the eccentric wheel. Chain plate directly carries and conveys material by the driving device. Operation chain plate forms an enclosed chain through sprockets.
