为了从动力学角度研究球磨机研磨，研究了样品硬度、进料重量和进料尺寸对研磨产品重量分数增加速率常数的影响。使用的样品是石英玻璃、硼硅酸盐玻璃、石英、长石、石灰石、大理石和滑石。卵石磨由一个长13.2厘米、直径12.8厘米的圆柱体和40个直径3厘米的球组成，总重量为1180克。在湿磨的情况下，向研磨机中添加400cc水。测试以临界速度的 88.1% 完成。对14~65目5种不同粒度的样品进行干磨，对20~65目4种不同粒度的湿磨进行实验，得到研磨速率常数。得到以下结果。
To investigate ball mill grinding from the kinetic point of view, the effects of hardness of samples, feed weight and feed size on the rate constant of weight fraction increase in the ground product have been studied. The samples used were silica glass, borosilicate glass, quartz, feldspar, limestone, marble and talc. The pebble mill consisted of a 13.2cm-long cylinder of 12.8 cm diameter and 40 balls of 3cm diameter having the total weight of 1180g. In the case of wet grinding, 400 cc-water was added to the mill. The tests were done at the speed of 88.1% of critical one. The experiments were performed on the samples of 5 different particle sizes from 14 to 65 mesh for dry grinding and 4 different ones from 20 to 65 mesh for wet grinding to obtain the grinding rate constant. The following results were obtained.
