Feb 21, 2019· 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.
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 over-grinding modern ball mills are fitted with dynamic separators (otherwise described as 'classifiers' or more simply as 'separators').
