Ball Mill Grinding Media Size

A ball mill, a type of grinder, is a cylindrical device used in grinding (or mixing) materials like ores, chemicals, ceramic raw materials and paints.Ball mills rotate around a horizontal axis, partially filled with the material to be ground plus the grinding medium. Different materials are used as media, including ceramic balls, flint pebbles, and stainless steel balls.

Optimization of mill performance by using

and with the decreased grain size, the necessary ball size also decreases (Olejnik, 2010; 2011). For each grain size there is an optimal ball size (Trumic et. al., 2007). The bigger ball in relation to the optimal one will have an excess energy, and consequently, the smaller ball mill has less energy necessary for grinding. In both
