Ball mills for superfine calcium carbonate. Ball mill classifier systems have been improved over time and are now capable of achieving much finer products. In the past, a particle size with a D97 of 10 microns was only possible. Now particle sizes down to a D97 of less than 3.5 microns can be achieved, with a D50 in the range of 1.5 microns.

The operating principle of the ball mill

The operating principle of the ball mill consists of following steps. In a continuously operating ball mill, feed material fed through the central hole one of the caps into the drum and moves therealong, being exposed by grinding media. The material grinding occurs during impact falling grinding balls and abrasion the particles between the balls.
