介绍了板锤式破碎机工作原理,并根据煤矸硬度相对差值、物料冲击速度和冲击次数对丟煤率和混矸率的影响进行计算与分析,导出冲击锤转速与煤矸硬度相对差值、冲击次数以及混矸率之间的数学表达式,使在不影响破碎分离效果的前提下设备最小化,机构合理化以适应井下生产环境。
The working principle of the plate hammer crusher is introduced. The influence of the relative difference of the coal gangue hardness, the impact velocity of the material and the impact times on the rate of the lost coal and the rate of the mixed rock is calculated and analyzed, and the relative difference between the speed of the hammer and the hardness of the coal gangue is derived Value, the number of impact and the mathematical expression between the rate of refuse, so that without affecting the crushing separation effect under the premise of equipment to minimize the institutional rationalization to adapt to the underground production environment.
