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 microns can be achieved, with a D50 in the range of microns.

A ball mill, a type of grinder, is a cylindrical device used in grinding (or mixing) materials like ores, chemicals, ceramic raw materials and 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 underlying foundation for strong, sharp edges, however, has to be a tool with a strong, thick core that makes the entire tool rigid. For this reason, the flutes are more open at the tip of the tool where space for chip evacuation is needed, but as the core runs up to the shank, it becomes heavier to provide integrity to the tool and resistance to deflection, Mr. Buchberger explains.

This mill is going to come in really handy for lots of future projects. I hope this page gives helpful ideas to anyone in need of a ball mill. They are quick, easy, and cheap to build yourself.
