摘　　要：介绍超临速磨机的结构 ,分析研究超临速磨机中矿石和钢球的运动规律 ,得出钢球在抛物运动阶段的轨迹方程和钢球对矿石的冲击速度公式。结果表明 ,钢球的抛物线运动轨迹主要决定于导向板下端点的位置 。The structure of ultracritical rotation speed mill has been introduced and the motion law of the balls and the ores in the mill has been analysed and studied. The motion locus expression and the highest crashing velocity of the balls have been deduced when the balls move along parabola locus. The results show that the parabola locus of the balls is mainly determined by the place of the low end of the guidance arc plate and the highest crashing velocity of the balls is determined by the rotation speed and the diameter of the mill.
