通过对 3.2 m× 3.1m格子型球磨机筒体衬板工作状况、磨损规律的考察和研究 ,将原小波形筒体衬板 ,改为圆沟形。这不仅提高了衬板的使用寿命 ,还能提高处理量 ,减少过粉碎 ,提高选矿回收率 ,减少噪声和减轻检修劳动强度。 Through the investigation and study on working conditions and wear rules of 衬 3.2 m × 3.1 m lattice ball mill liner, the original small corrugated cylinder liner was changed to circular ditch. This not only increases the service life of the liner, but also increases throughput, reduces over-pulverization, increases beneficiation recovery, reduces noise and reduces overhaul labor.
