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. This energy is required to cause grinding of the material in the mill

To get rid of pulp and rocks in the charge, a mill grind-out no ore feed of 10 to 20 minutes is also performed before mill inspection or relining. The complete grind-out is required to obtain the accurate ball load measurement or the percentage by volume of balls in the mill. This is usually performed soon after a crash stop.
