DEVICE FOR ADJUSTMENT OF REDUCTION RATIO IN SCREENLESS HAMMER CRUSHER

摘要

FIELD: process engineering.SUBSTANCE: invention relates to crushers for grinding ball-shape materials with diameter smaller than length. Proposed device comprises loading bin with two adjusting moving shutters arranged at different height. Top shutter is inclined toward crusher working chamber. Bottom shutter is mounted with reverse inclination angle with respect to top shutter. Said shutters serve to feed corn seeds uniformly and directly to rotor hammers. This allow feeding ground corn to crusher different levels, hence, to increase duration of stay.EFFECT: higher quality of grinding, uniform grain size, reduced power consumption.3 dwg
