Cement mill - Wikipedia, Heat generated in the grinding process causes gypsum CaSO 4.2H 2 O to lose water, forming bassanite CaSO 4.0.2-0.7H 2 O or γ-anhydrite CaSO 4. 0.05H 2 O . The latter minerals are rapidly soluble, and about 2% of these in cement is needed to control tricalcium aluminate hydration.

Subcoal ,Subcoal technology is used to process paper plastic waste fractions into a substitute for coal or lignite. The fuel pellets can be used as secondary energy source in industrial furnaces, such as lime kilns and cement kilns, coal-fired power stations and blast furnaces. Subcoal has a caloric value comparable with lignite.

Manufacturing Process – Continental Cement, Step 6 : Finish Grinding. The clinker is ground in a ball mill—a horizontal steel tube filled with steel balls. As the tube rotates, the steel balls tumble and crush the clinker into a super-fine powder. It can now be considered Portland cement. The cement is so fine it will easily pass through a sieve that is fine enough to hold water.
