щёковая дробилка (A crusher is a machine designed to reduce large rocks into smaller rocks, gravel, or rock dust. ... A jaw crusher uses compressive force for breaking of particle. This mechanical pressure is achieved by the two jaws of the crusher of which one is fixed while the other reciprocates. A jaw or toggle crusher consists of a set of vertical jaws, one jaw is kept stationary and is called as fixed jaw while the other jaw, called as swing jaw, moves back and forth relative to it, by a cam or pitman mechanism, acting like a class II lever or a nutcracker.
