As the core machine of mineral processing equipment, ball mill assumes an indispensable position and production capacity. If the ball mill fails on the beneficiation production line, it will affect the overall production. Therefore, once the ball mill equipment fails, it should be resolved immediately without affecting the overall production line. So what are the bad things about the ball mill?

One of the more difficult problems is the displacement of the cylinder. If it is ignored, the displacement will become larger and larger, resulting in serious wear and tear of the machine, and finally directly affect the service life and production capacity of the machine. The corresponding measures are described below.

Machining 8 M16 bolt holes on the other side of the spiral barrel for installation - the flange and the screw are fixed. The flange and 4 fixed bolts are fixed in the hollow shaft under the constraints. There is a gap between the outer surface of the spiral cylinder and the inner hole of the hollow shaft. When the grinding body rotates, the spiral cylinder moves on an oval track in the inner hole of the hollow shaft. The outer surface of the spiral cylinder and the inner hole of the hollow shaft are clearance fit, the design minimum clearance is 0.5 ram, and the maximum clearance is 1.12 ram. The hollow shaft has no relative movement. During the rotation of the cylinder, the grinding body also has a phenomenon of slipping. During the sliding process, the material is given a grinding effect. In order to effectively use the grinding effect, when grinding the material with a larger particle size of generally 20 mesh, the grinding body cylinder Divided into two sections by partition board, it becomes a double warehouse. When the material enters the first warehouse, it is crushed by steel balls. When the material enters the second warehouse, the steel end grinds the material, and the finely ground material is hollowed out from the discharge end. Shaft discharge, when grinding materials with small feed particles, such as sand No. 2 slag, coarse fly ash, the mill cylinder can be a single-silo mill without partitions, and the grinding volume can also be used for steel sections . In addition, the axial reaction force generated during the conveying process of the screw cylinder and the vibration generated by the hammering of the steel ball cause the loosening of the connecting bolts to form a slippery wire phenomenon, resulting in the displacement of the screw cylinder. On the mating surface of the outer wall of the spiral cylinder - add 4 M24 bolt holes along the circumferential direction, and fix the spiral with bolts.
