The grinding media Ball bounces seriously, causing part of the energy loss in the rebound, so the energy of grinding media ball is not more used for crushing, thus affecting the crushing; 2 When the ball and the ball contact with each other, sliding severe, cannot effectively engage in the ball between the mineral particles, so that the ...
A ball mill is a drum-grinding unit where balls from solid materials (steel, iron, hard alloys, ceramics, etc) are used. Most common are ball mills, where when the drum rotates and the balls rub against the inner walls, the balls are lifted until the lifting angle becomes bigger than the angle of repose. Then the grinding media are again below.
