2015年4月1日  One type of impact crusher is a hammer mill. These operate by striking falling particles by near vertically oriented hammer surfaces attached rigidly or via hinges to a central horizontal impeller rotating at high speed (typically between 750 and 1800 rpm). Hammer mills rely on impact rather than pressure to crush material.
