Grinding of clinker consumes power in the range of 2.5 kWh/ton of clinker produced. These and other pyroprocessing parameters make cement production costly. The pyroprocessing process in kilns and the grinding technologies therefore have to be optimized for best processing. This paper discusses the cement manufacturing and grinding processes.

Clinker grindability is determined by quantity of electricity consumed for grinding (kW / ton) under other equal conditions. In cement production entire crushing and grinding process consumes about 85% of the electricity. At the same time 75% of electricity consumed for milling and only 2-20% of them consumed for grinding.

Clinker Grinding is the final step in cement production. The cooled clinker is a kind of granular material with different particle size. They will be ground in the grinding mill to reach the qualified fineness of cement product. During the grinding, 2-3% gypsum powder is added as retarder so that when cement contacts with water, its ...

A cement mill is a grinding machine that used to grind hard, nodular clinker from cement kiln into fine powder that is cement. At present, most cement is ground in ball mills. As the rapid development of construction, more and more cement are required. Grinding systems are either 'open circuit' or 'closed circuit.'.

Clinker — Wikipédia

Le clinker est un constituant du ciment, qui résulte de la cuisson d'un mélange composé d'environ 80 % de calcaire (qui apporte le calcium) et de 20 % d'aluminosilicates (notamment des argiles qui apportent le silicium, l'aluminium et le fer). La « farine » ou le « cru » est formée du mélange de poudre de calcaire et d'argile. Cette cuisson, la clinkérisation, se fait à une ...
