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').

Cryomill - the perfect mill for cryogenic grinding - RETSCH

Usually, grinding only takes a few minutes so that the sample does not get warm during the process. If, however, longer grinding times are required, it is also possible to pre-select periods of intermediate cooling and the number of cryogenic cycles. All instrument parameters are retained during standby operation for subsequent processes.
