May 08, 2012· Roller mills are more energy efficient than hammer mills when grinding friable materials; the advantage for corn is <5% at sizes smaller than 500 microns, becomes 25-30% at 800 microns, and increases to perhaps >80% at a size of 3000 microns (CPM, 1992). The hammer mill (Figure 4) remains the industry standard for size reduction.

### TECHNICAL NOTES 8 GRINDING R. P. King - Mineral Tech

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.
