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.

The ball impact energy on grain is proportional to the ball diameter to the third power: 3 E K 1 d b. (3) The coefficient of proportionality K 1 directly depends on the mill diameter, ball mill loading, milling rate and the type of grinding (wet/dry). None of the characteristics of the material being ground have any influence on K 1.

Table 3 is a summary of the preliminary tests (in duplicate) using various proportions of balls and pebbles. The on-line torque measurement was used for early measurement of the power drawn by the mill, so that the grinding time could be calculated, to maintain the same amount of energy for all tests (i.e. assuming a constant grinding efficiency).
