Ball Grinding Process | SpringerLink
Ball grinding process is a grinding method of crushing ore with ball-shaped grinding medium in the grinding mill. In the ball grinding process, because the steel ball has 360° free rotation, it is suitable for falling motion and throwing motion. When the rotating speed of the cylinder is low, the medium rises to a certain height along the ...
