Cement clinker - Wikipedia
The Portland clinker essentially consists of four minerals: two calcium silicates, alite (Ca 3 SiO 5) and belite (Ca 2 SiO 4), along with tricalcium aluminate (Ca 3 Al 2 O 6) and calcium aluminoferrite (Ca 2 (Al,Fe) 2 O 5).These main mineral phases are produced by heating at high temperature clays and limestone. [3]The major raw material for the clinker-making is usually limestone

Cement mill - Wikipedia
Portland clinker is the main constituent of most cements. In Portland cement, a little calcium sulfate (typically 3-10%) is added in order to retard the hydration of tricalcium aluminate.The calcium sulfate may consist of natural gypsum, anhydrite, or synthetic wastes such as flue-gas desulfurization gypsum. In addition, up to 5% calcium carbonate and up to 1% of other

Ball mill - Wikipedia
A section cut-through of ball mills. A ball mill is a type of grinder filled with grinding balls, used to grind or blend materials for use in mineral dressing processes, paints, pyrotechnics, ceramics, and selective laser sintering.It works on the principle of impact and attrition: size reduction is done by impact as the balls drop from near the top of the shell.
