摘要

The crusher has grinder casing (1) having wedge-shaped grinding chamber (10) attached to input hopper (2). The grinding chamber is arranged between fixed crushing jaw (3) and movable crushing jaw (4). An eccentric shaft (5) is used for driving crank arm at an upper end of movable crushing jaw. A shaft drive (9) is arranged laterally inside the grinder casing. A swing arm is detachably mounted to grinder casing, to enable removal of fixed and movable crushing jaws within the grinder casing, so as to access the replaceable crushing plate (41) attached to movable crushing jaw.
