WATER-HAMMER ACTUATED CRUSHER

摘要

A crusher for materials such as rock is described. Material is crushed between an inclined anvil (36) and a vibrating impact surface (34). The impact surface (34) is driven by high intensity pressure pulses which are generated by creating repeated water hammers in a low pressure high volume hydraulic circuit (65). The water hammer may act directly to drive a piston (53) bearing the impact surface (34) toward the anvil (36). In another configuration of the invention, the water hammer pulse stores energy by stretching a tension member (292) or by distorting a plate (190). When the water hammer pulse passes the stored energy suddenly drives the impact surface towards the anvil. The crusher of the invention has few moving parts and is energy efficient.
