SU1685519A1 - Centrifugal crusher for fragile materials - Google Patents

Abstract

The invention relates to a centrifugal crusher for brittle materials, mainly coal, and makes it possible to increase its reliability in operation. The material enters the central part of the accelerating disk 3. rotating around a vertical axis, is pressed against the accelerating blades 4 and moves to the moving peripheral parts 6 of these blades protruding beyond the limits of the disk 3, where it is crushed by colliding with the projections 8 on the housing 1 which are located above the peripheral parts 6 blades 4. Incompetent objects deflect the moving peripheral parts of the 6 blades 4 into the grooves located behind the blades 4 on the acceleration disk, and fall out without damaging the projections and blades. 2 Il.
