Applied material:

pebble, limestone, granite, basalt, diabase, andesite, etc

Features: 

1.High crushing ratio, adjustable discharging size.
2.No grates device, not easily blocking for crushing high moisture, sediment materials.

Working principle: 

Materials drop into high speed rotating impeller in vertical, under high speed centrifugal force, stroked and crushed with materials scattered around the impeller in umbrella, after repeatedly impacting then there will be forming eddy current between the impeller and frame, materials will be crushed again and finally discharge from outlet directly, whole system formed closed circuit, separated by outer screen to control fineness.
