grinding in the cement process

Cement Grinding - 911 MetallurgistMar 17, 2017 . This phase of grinding may be either the wet or dry process, the end product going to a kiln. Material ground consists of line, cement rock, marl or marine shells along with secondary materials usually shale or clay. A typical raw mix consists of 75-85% line, 12-25% shale, the balance consisting.grinding in the cement process,Cement mill - WikipediaHeat generated in the grinding process causes gypsum (CaSO4.2H2O) to lose water, forming bassanite (CaSO4.0.2-0.7H2O) or γ-anhydrite (CaSO4.~0.05H2O). The latter minerals are rapidly soluble, and about 2% of these in cement is needed to control tricalcium aluminate hydration. If more than this amount forms,.
