As a general rule, there should be less than 25% of clinker that is below 1mm in size. Coarse clinker is more of an issue for ball mills. Some cement groups use a formula, such as Bond's, to calculate the maximum ball size required in a ball mill, based on the average size of the clinker feed. However, one drawback with this approach is that ...

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.

Clinker (in cement industry) is transitional product in cement production. Upon heating mixture obtained from limestone (about 75%) and clay (about 25%) partial melting occurs and clinker granules are formed. Clinker and gypsum (about 5 %) are mixed and finely milled to obtain cement. Gypsum control the setting properties of the cement.
