GRINDER OF PRODUCTION WASTES Russian patent published in 2012 - IPC F23G5/33 

FIELD: process engineering.

SUBSTANCE: proposed device comprises rotor, case that doubles as stator, and feeder. Feeder is secured on case, in the plane of rotor rotation, at 5.0-40.0 mm from vertical centre axis of rotor symmetry to lengthwise axis of feeder symmetry, on their left or right. Feeder has round or rectangular opening. Feeder height makes, at least, fivefold diameter of said opening. Material to be crushed is fed in crushing zone in definitely directed state. This is possible due to feeder height and cross-section mating material surface shape.

EFFECT: simplified design.
