Options: Ball or jar milling are often utilized for this purpose (Figueiredo et al., 2018; Gjorv and Sakai, 1999), as well as use of eccentric shaft rotors (Shaban et al., 2019). Variable ball loading, durations, and rotation speed can be applied (Dimitriou et al., 2018).
Discontinuous operated drum mills make, in addition to size reduction, homogenization of the material to be ground possible. Drum mills have a horizontal grinding drum rotating around a fixed center of rotation. Loed in this cylindrical working space is a grindingmedia filling, which is tumbled by the rotating grinding drum.

The mill centrifuge point is called as Critical Speed, and ball mills mostly function at 65% to 75% of the critical speed. In general the ball mills are utilized to grind material 1/4 inch and better, 20 to 75 microns down to the particle size. Also, to have excellent efficiency with the ball mills, they must be functioned in closed circuit system.
