Ball Mills - an overview ScienceDirect Topics

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’).
