The use of mechanical energy to break down particles through various mechanical forces including grinding media, pegs, rods, pebbles, and screens. When the material is pumped through the mill, the mill's components act on the solids in the mixture to tear them apart or crush them, further reducing them in size.

Clinker grinding technology is the most energyintensive process in cement manufacturing. Traditionally, it was treated as "low on technology" and "high on energy" as grinding circuits use more than 60 per cent of total energy consumed and account for most of the manufacturing cost. Since the increasing energy cost started burning the benefits significantly, the [.]
