Comminution - Wikipedia

Comminution is the reduction of solid materials from one average particle size to a smaller average particle size, by crushing, grinding, cutting, vibrating, or other processes. In geology, it occurs naturally during faulting in the upper part of the Earth's crust. In industry, it is an important unit operation in mineral processing, ceramics, electronics, and other fields, accomplished with ...

Clinker grinding with limestone - Page 1 of 1

Dec 08, 2014  re Clinker grinding with limestone. Hello Shastri, 100oC seems a bit low. Normally you should try to keep the mill outlet temperature at between 110 and 115oC. Have you tested the water content of the cement blocking the diaphragm? If you use water sprays they may not be atomising correctly, causing localised buildup of moist cement.
