浅谈乳化液冲击破碎锤式工作面大块煤（矸）破碎装置

摘要

Breakthrough quasi static breaking coal approach and the existing hydraulic crushing hammer with high light load impact mode, put forward creatively the low frequency and heavy crushing principle and the use of low frequency, heavy loading scheme to develop a hammer and energy storage separated type emulsion impact crushing hammer and large integrated lfow control valve, which can complete the breaking or cracking coal that the hardness F is lower 6.%突破准静态的破煤方式和现有液油压破碎锤的高频轻载冲击模式，创新提出低频重载的破碎原理并采用低频、重载方案，开发出锤头和蓄能器分离式乳化液冲击破碎锤以及超大流量集成控制阀，可完成硬度 f6以下大块的大范围的破断或裂解。
