CRUSHING AND LOADING DEVICE

 

Crushing and loading plant (DPU) with circular feeder is designed for crushing and loading coarse-grained rock.

Operating principle of the circular feeder is as follows: feed material moves in the inclined circular chute; rigidly connected outer circular wall and bottom of the chute are moveable; fixed inner circular wall is in the top portion provided with opening above the crusher. This opening has dimensions that prevent oversized pieces from passing through it. Oversized pieces which are disposed on the moveable bottom, cannot pass through the opening and get into the oversized rock extractor, which throws oversize outward or feeds it to the rock breaker.
