摘　　要：对准600×400mm型球磨机不同型式衬板进行磨矿实验,采用回归分析法研究了每种衬板结构对应的磨矿动力学方程。研究结果表明:所得磨矿动力学方程准确、可靠,能够真实准确的反映不同衬板时磨矿过程及结果;磨矿时间相同时,对应不同的衬板面角,衬板高度越大,待磨粒级(200目以下粒级)的分布率越小;当衬板高度相同时,随着面角的变化,待磨粒级(200目以下粒级)的分布率有一个最大值,此最大值对应的衬板面角为70°。Do experiments on the different types of liners of the φ600×400mm ball mill, and then study the grinding kinetic equation of each liners by the method of regression analysis. The results show the follows： firstly, the grinding kinetic equations that we gained are accurate and reliable, which can reflect the grinding process and the outcomes of different liners; secondly, if the grinding time is same, with different liner face angles, the greater height of liner, the smaller of the distribution rate of abrasive grade （200 mesh size fraction less）; thirdly, if the height of each liners is same, the distribution rate of abrasive grade （200 mesh size fraction less） change with the face angles and it has a maximum value, and then the liner face angle is 70°.
