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.

Cement Mill Wikipedia

A Ball mill is a horizontal cylinder partly filled with steel balls or occasionally other shapes that rotates on its axis imparting a tumbling and cascading action to the balls. Material fed through the mill is crushed by impact and ground by attrition between the balls. The grinding media are usually made of high-chromium steel.The smaller grades are occasionally cylindrical pebs .
