Grinding is an energy intensive process and grinding more finely than necessary wastes energy. Cement consists of clinker, gypsum and other components mostly more easily ground than clinker. To minimise overgrinding modern ball mills are fitted with dynamic separators (otherwise described as 'classifiers' or more simply as 'separators').

The cooling process is required to stop the chemical reactions at the right moment, allowing to obtain a proper quality of the products. Moreover, the cooling process allows to recover some heat from the hot clinker. Finally, the cooled clinker is stored inside silos and then fed to specific mills for the finish grinding process.

Introduction to Crushing and Grinding of Bauxite. The most common initial process step to feed an alumina refinery with bauxite is the crushing or sizing of the raw bauxite material that is extracted from the mine. The feed material is crushed or sized so that it is conveyable, as well as correctly dimensioned, for the next step in the process.

Energy efficiency in clinker production. The cover story captures the journey of an ageold system of grinding to the present one. It covers from mill internals to the use of grinding aids. A cement clinker is usually ground using a ball mill. This hardware is generally divided into two or three chambers, with different size of grinding media.

Composition and preparation 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]
