Cement Grinding: cement grinding is the final stage in Portland cement manufacturing. In this step, clinker will be ground in grinding mill to reach the qualified fineness of cement product. During the grinding, we usually add gypsum, fly ash and other raw materials into the cement to realize the different usage of cement.

The Tovarov grindability index is used to determine the influence of materials on the cement clinker grinding capacity of a mill; the basis is rotary kiln clinker with a defined grindability index of a = 1. According to this, a mill grinding 30 t/h clinker, will grind 30 x = 42 t/h of marl or 30 x = 18 t/h of silica sand.
