Milling was carried out in a laboratory ball mill 312×284 mm (diameter × length). The ball distribution was fixed at equal volume fraction of 15 and 23 mm balls. The mill speed was set on N c =71%. The concentrate was charged to the mill and rotated for a specific time, and then discharged. Five samples with different Blaine specific

Ball mills for super-fine 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.

Rod mills are used in an open circuit between crushing and the ball mill. They often operate in wet and where the pulp contains up to 50% solid by mass. This machine is equally very applicable to dry where it could take a feed that has achieved 6% moisture. As such, when the product is sticky, rod mills are preferred over ball mills.
