Mill (grinding) Wikipedia

A mill is a device that breaks solid materials into smaller pieces by grinding, crushing, or cutting. Such comminution is an important unit operation in many processes.There are many different types of mills and many types of materials processed in them. Historically mills were powered by hand (e.g., via a hand crank), working animal (e.g., horse mill), wind or water ().

Temperature control. 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. If more than this amount forms
