摘　　要：从理论上将砂块视为质点,分析了砂块在无能量损失的情况下在滚筒中的运动轨迹,求出了滚筒破碎筛转速与滚筒半径的函数关系。按此函数关系选择滚筒转速可使砂块具有最大撞击能,由此可获得最佳破碎效果。The sand lump is theoritically regarded as the mass point. Basing on this, the paper analyses the moving trace of the sand lump in the drum under the condition of-without energy being loss and finds out the functional relation within the revolving speed of the drum breaker screen and the radius of the drum. As the revolving speed of the drum is determined by making good use of this funtional relation, the sand lump will possess maximum impact energy and optimum break results will be achieved.
