Jun 20, 2015· The effect of Ball Mill RPM speed going from sub-critical to super-critical helps understand the Ball Mill Working Principles of ball-on-ball VS ball-on-shell grinding.
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.
