SAG mill liners | Sinco

SAG mill liners are different from ball mill liners. the diameter and input size of SAG mill is larger than ball mill. And the grinding media are more less than ball mill. The mining materials need to be a part of grinding media. That means the SAG mill should be hard enough to resist the impact from the mining rocks and not be yield or bend.

Uses of a ball mill liner The role of a ball mill liner is to give the mill heads protection against wear and tear thus increasing their lifetime and creating optimal grinding efficiency. The design of a ball mill liner depends on the drilling pattern of the mill heads, the rpm speed of the mill, the maximum grinding diameter of the media and the percentage of media filling.
