球磨机转筒临界转速与脱离角的计算

The Calculation of the Critical Rotation of the Drum of Sphere-grinding Mill and Disjunctire Angle

本文给出了球磨机转筒临界转速的定义，并由此导出确定临界转速的方法，在分析钢球在转筒内运动的基础上，导出钢球脱离角的计算公式。

The article has defined the critical rotation speeed of the drum of Spheregrinneling mill and therefore deduced the dthod of how to determine the critical rotation speed. It also leads to the calculating formula of the disjunctive angle of steel sphere.
