Ball mill is a cylinder rotating at about 70-80% of critical speed on two trunnions in white metal bearings or slide shoe bearings for large capacity mills. Closed circuit ball mill with two compartments for coarse and fine grinding and a drying compartment with lifters are generally found in cement plants for raw material grinding.

The action of the mill is to a large degree autogenous – that is, the motion of the larger chunks of raw material crushes the smaller pieces. This is particularly the case where the chalk contains flints: in this case the mill is designed primarily to keep the flints in violent motion, and these in turn grind the softer minerals by a mixture ...

Raw Mill Main Motor . A raw mill is the equipment used to grind raw materials into "rawmix" during the manufacture of cement.
