During bolt tensioning trials, MPS brought in a pulp lifter liner, configured with M48 liner bolts, from a 36-foot SAG mill. The test jig was used to calibrate actual torque/bolt load and, through proper lubrication, get it closer to the calculated torque/bolt loads to reduce the variation in the bolt loads achieved.

Generally, mill liners are of two types, namely, LIFTERS & CLASSIFIERS. The lifting type raises the balls to a certain height above the horizontal central line of the mill, from where they fall onto the balls and the balls spin or rotate against each other in the bottom of the mill, thereby, grinding the material by attrition.
