Ball Mill - PrintWiki

The ball mill consists of a closed horizontal metal cylinder, containing the balls at the bottom. The ink slurry is put into the machine to partially fill the cylinder. The cylinder is rotated, and the tumbling of the balls generates frictional forces which break up and disperse the pigment particles.
