2020-11-27 · A ball mill rotates its long shaft, and drive a jar which is placed on it. The friction of the rubber surface of the shaft can rotate the jar. The grinding beads (grinding balls) in the jar will constantly hit the sample due to gravity and mechanical force. After a long period of rotation and impact, the sample gradually changes from large pieces to small pieces, and small pieces to powder.Basic knowledge of Ball Mill CHUKOH SEIKI CO., LTD.,When a certain amount of balls as a grinding medium is introduced into a cylindrical container and rotated about a horizontal axis, the ball is lifted up to a certain height along the inner wall with the rotation of the cylindrical container and slides on the inner wall Or it rolls over the ball layer and circulates in the cylinder in a certain direction.

2016-10-10 · A cylindrical ball mill used for grinding the coarse material. This mill should have a short length because the balls distributed uniformly over the entire length of the mill and during rotation obtained the same pulse. The drum diameter of the cylindrical ball mill should be the greater, the larger the pieces of crushed material. Pic. 3.
