The mill gear should be lifted by the pinion causing a downward pressure on the pinion shaft bearing. Mills are made either right or left "hand". There are two methods of identifying the "hand" of the mill. When standing at the feed end of the mill, and facing the mill, if the mill rotates clockwise, it is a right hand mill.

Continuous blending involves simultaneous feeding of the silo, overflow to a second silo and final discharge to kiln feed. Modern equipment generally uses continuous CF silos, each having capacity of more than 24hours' kiln feed and yielding a blending ratio (or 'blending factor') of 48, or around 23 for older silos.
