Ball milling is a grinding technique that uses media to effectively break down pigment agglomerates and aggregates to their primary particles.using a rotor or disc impeller to create collisions of the grinding media, the impact and force created by the bead mills collisions break down the pigment agglomerates.
Ball mills are used primary for single stage fine grinding, regrinding, and as the second stage in two stage grinding circuits.according to the need of customers, ball mill can be either wet or dry designs.ball mills have been designed in standard sizes of the final products between 0.074 mm and 0.4 mm in.
Between vertical mills and ball mills arises from differences in the frequency and energy intensity of ball collisions.the higher efficiency of the vertical mills is due to the higher frequency of lower energy impacts and, by the same token, lower frequency of higher energy impacts when compared to conventional ball mills mazzinghy et al., 2013.
