我厂用的是φ2100×8000球磨机,原为一般锰钢波形衬板,处理硬度为f=8～11的铁矿石。在多年的生产实践中发现,衬板耐磨性差,磨损不均匀,其平均使用寿命为3400小时左右;波形衬板螺栓较多,易被磨损;衬板带球能力差,影响磨矿效率的提高,致使分级机返砂量 I plant is used φ2100 × 8000 ball mill, the original manganese steel corrugated liner, the hardness of f = 8 ~ 11 iron ore processing. Found in many years of production practice, lining wear poor, uneven wear and tear, the average life of 3400 hours or so; wave liner bolts more vulnerable to wear; liner ball with poor ability to affect the grinding efficiency Improve, resulting in grading machine back to the amount of sand
