分析了具有梯形衬板的筒式球磨机外层钢球的抛落规律,提出了衬板尺寸的确定方法及计算程序,实例计算表明,按本文计算方法所设计的衬板,在转速率及钢球直径不变的情况下,可提高钢球对物料的冲击力11%。
The dropping rule of outer ball of drum mill with trapezoidal liner was analyzed. The method of determining the size of liner and the calculation program were put forward. The calculation results show that the liner designed according to the calculation method in this paper has better performance in the revolution rate and steel Under the condition of constant ball diameter, the ball impact on the material can be increased by 11%.
