Grinding Ball Mill Copper Concentrator

Nov 26, 2019· The feed of the ball mill contains grinding balls. In order to effectively reduce the direct impact of materials on the ball mill feed bushing and improve the service life of the ball mill feed bushing, the feeding point of the groove in the feeding part of the ball mill must be as close to the side of the mill barrel as possible.

Recent trials at a large copper concentrator have shown that bolt removal time was halved by using Easy-Out Bolts. The positive location between the moil, or drift, and the bolt eliminates the risk of mill damage due to misalignment of hydraulic hammer moils or sledgehammer damage around bolt holes.
