End Liners Feed and Discharge. Our design objective is to ensure feed end liners match life of shell liners to reduce multiple mill stoppages. The discharge end liners include pulp lifters and grates (slotted plates) have a pivotal role in SAG mill operation for optimum particle breakage rate, slurry discharge rate, eliminate flow back and slurry pooling.

The vibrating ball mill also works on the principle of attrition and impact. It consists of a mill shell containing a charge of balls similar to that of ball mills. In this case, the shell vibrates due to some frequency rather than rotated. Uses (i) Small capacity ball mills are used for the final grinding of drugs or for grinding suspensions.
