Ball Mills an overview ScienceDirect Topics
In a ball mill, size reduction takes place by impact and attrition. In a vertical mill the bed of material is subject to such a high pressure that individual particles within the bed are fractured, even though the particles are very much smaller than the bed thickness.

Cement Kilns: Size Reduction and Grinding
In 1904, Krupp produced a self-contained cement mill using a ball mill and their version of the Askham separator in closed circuit, but I think this was never used in Britain. However, from the mid 1890s, ball mills were used in combination with tube mills (see below) and this setup became the normal cement milling installation until 1920.
Ball Mill: Operating principles, components, Uses
The balls which could be of different diameter occupy 30 -50% of the mill volume and its size depends on the feed and mill size. The large balls tend to break down the coarse feed materials and the smaller balls help to form fine product by reducing void spaces between the balls. Ball mills grind material by impact and attrition.
