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 working principle is that cement is removed from the mill before overgrinding has taken ...
