Industrial closedcircuit tube (or ball) mill schematically presented in Figure 1 was used for cement production. The clinker initially passes through a doubledeck screen, where all particles larger than 10 mm are sent to a precrusher. A measured fresh feed mixture (B0) of precrushed clinker, gypsum, and pozzolan is introduced in the mill.

The common intergrinding of limestone and clinker in classical ball mills is therefore producing a cement of very high surface. The higher the limestone content, the higher the negative impact of its surface on water demand and powder flowability.
