球磨机有用功率采用“单个钢球动能累计法”进行计算,与传统定积分计算方法不同,考虑了钢球直径大小等因素,与传统计算方法对比,相差极其微小。试算证明,这种计算方法虽然繁锁,但推理直观,具有较高的准确度,不失为验证传统计算方法是否准确的一种手段。 The useful power of the ball mill is calculated using “single ball kinetic energy accumulative method”, which is different from the traditional fixed integral calculation method. Considering the diameter of the steel ball and other factors, the difference is very small compared with the traditional calculation method. Trial calculations show that although this method of calculation is cumbersome, reasoning is intuitive and has high accuracy, after all, as a means of verifying the accuracy of traditional calculation methods.
