1. Introduction. Cement grinding is a key process in the cement industry. During this phase, gypsum and mineral or artificial raw materials (eg pozzolan, ash, limestone) are added to the clinker (basic raw material for cement production) and, then grinded in special mills until a very small grain size is achieved.
