钢球级配对球磨机磨矿效果影响试验

摘要

By comparison granular distribution,grinding efficiency,grinding technique efficiency, with six initial ball granulometric classes,the optimum ball granulometric class was determined with Ø100,Ø70,Ø50,Ø30 mm mass ratio of 15∶25∶30∶30,neither too many or too few large ball is benefi-cial to increase of grinding efficiency.The research results had some guidance in plants for improving grinding efficiency.%通过6种不同初装球配合比情况下磨矿产品的粒度组成、磨矿效率和磨矿技术效率的比较，发现初装球中直径为Ø100、Ø70、Ø50、Ø30 mm 的钢球质量比以15∶25∶30∶30为宜，大球过多或过少均不利于磨矿效率的提高，这为选厂提高磨矿效率有一定的指导意义。
