1. Liners protect the outer shell of the mill from wear - liners are renewable. 2. Lifters prevent slipping between the medium and slurry charge in the mill and the mill shell. Slippage will consume energy wastefully but more importantly it will reduce the ab ility of the mill shell to transmit energy to the tumbling charge.

Shell mills have several inserts on the outer edge of the cutter, so when the cutter first hits the material, it removes a small amount of stock – depending on your depth of cut. As the cutter passes over the workpiece, the other teeth actually work to remove stock that was left as a bur or as a result of the springing of the workpiece or cutter.
