Tips for designing an efficient crushing and screening operation
These feeders perform a dual function of feeding/conveying and separating smaller material to bypass the primary crusher The oversize materials are discharged off the feeder into the primary crusher This machine has speed controls but cannot control the feed rate to the crusher as precisely as the apron feeder
Selecting feeders for optimized success Pit & Quarry
Adjustable grizzly openings provide some control over the size of material being fed into the crusher as well as what is rejected ahead of the crusher This saves crusher wear cost while boosting plant capacity It should be understood too that VGFs rely on a vibrating mechanism to lift and throw the material down the length of the feeder pan
