The discharged raw mix (limestone 70%, clays 30%) is conveyed to a raw mill bin for later grinding. The other raw materials that are used in cement manufacturing, called additives, are also stored in separate bins. 3. Drying and grinding. The raw mix and required additives are fed from their bins to the raw mill via blowers for drying and grinding.

Therefore, for various thermal power plants using coal and limestone, some improvement in mill efficiency and energy cost can be expected if the same grindability test is used for both coal and limestone (Hower et al., 1992). The HGI value is used in empirical equations concerning grindability such as the efficiency of mills and wearing of mills.
