ABSTRACT:
A crusher for materials such as rock is described. Material is crushed between an inclined anvil and a vibrating impact surface. The impact surface is driven by high intensity pressure pulses which are generated by creating repeated water hammers in a low pressure high volume hydraulic circuit. The water hammer may act directly to drive a piston bearing the impact surface toward the anvil. In another configuration of the invention, the water hammer pulse stores energy by stretching a tension member or by distorting a plate. 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.
