球磨机筒体锰钢衬板在使用中,受钢球和矿块撞击作用,裂损现象时常发生,尤其是在衬板使用寿命后期更为严重。就MQG2100×3000球磨机而言,锰钢衬板使用寿命为8个月左右。衬板使用到第6个月后,每月衬板裂损平均在6～8块,停机拆除更换不少于4次,每次以8h计,在第6至第8个月期间,总计增加检修时间约为96h。造成经济损失约20万元。 1.衬板损坏原因 衬板在使用周期后期,衬板厚度因磨蚀而日渐变薄,断面积
Ball mill cylinder manganese steel liner in use, by the impact of steel balls and nuggets, cracking often occur, especially in the later life of the liner more serious. For MQG2100 × 3000 ball mill, manganese steel liner life of about 8 months. After the use of the liner to the 6th month, the average length of the liner was 6 to 8 pieces per month, and the disassembly and disassembly of the liner was not less than 4 times. Each time it took 8h, it increased in total between the 6th and the 8th month Maintenance time is about 96h. Cause economic loss of about 200000 yuan. 1 lining the cause of the damage lining in the later period of use, liner thickness due to erosion and thinning, the cross-sectional area
