我矿现有2台φ1.5×3.0格子型球磨,3台φ1.5×3.0溢流球磨机。年处理原矿16￣17万t,从1989年投入生产以来,衬板一直使用(ZGMn13)高锰钢,近年来随着原矿处理量的增加,衬板消耗呈直线上升。2000年衬板消耗达13套之多,平均使用寿命为3个月左右。1问题分析高锰钢材质的主要特点是在
My mine now has 2 φ1.5 × 3.0 grid ball mill, 3 φ1.5 × 3.0 overflow ball mill. Annual processing of 16 to 170,000 tons of raw ore, put into production since 1989, the liner has been using (ZGMn13) high manganese steel, ore handling in recent years with the increase in liner consumption rose in a straight line. Liner in 2000 up to as many as 13 sets, the average life expectancy of about 3 months. 1 Problem Analysis The main characteristics of high manganese steel is in
