At all times, the slurry leakage in the feed inlet of the autogenous tumbling mill chiefly influences the operation efficiency of the mill, which affects the production, quickens the abrasion of the quill shaft, increases the maintenance time and decreases the lifespan of the mill.
自磨机进料端漏浆问题一直是影响自磨机运转率的主要原因，它影响生产，加剧中空轴的磨损，增加维修时间又降低设备的使用寿命。
The quill shaft adopts cast steel part and the liner is detachable. The turning gearwheel adopts casting hobbing process and the drum is equipped with wear-resistant liner, which has good wear-resistance.
中空轴采用铸钢件，内衬可拆换，回转大齿轮采用铸件滚齿加工，筒体内镶有耐磨衬板，具有良好的耐磨性。
The material goes to the first hopper after the spiraling by the quill shaft from the feeding equipment. The hopper has ladder sheathing or corrugated sheathing with steel balls inside, which will fall under the effect of centrifugal force by barrel turning to ram hard and grind material.
物料由进料装置经入料中空轴螺旋均匀地进入磨机第一仓，该仓内有阶梯衬板或波纹衬板，内装不同规格钢球，筒体转动产生离心力将钢球带到一定高度后落下，对物料产生重击和研磨作用。
The fracture causes of joining bolt joined between feeder and quill shaft of ball mill are biggish gap between feeder and quill shaft, defective seal cone washed by ore pulp. etc.
球磨机进料器与中空轴联接螺栓断裂原因是进料器与中空轴之间间隙过大，密封锥面受矿浆冲蚀而被破坏。
