Bal mill opposite rotarion effect grinding

The grinding effect of the ball mill is completed based on the movement of the medium its rotationin body. Therefore, it is necessary to study the motion ... tendency to rotate the medium in the direction opposite to the direction of rotation of the cylinder. If the friction moment to the cylinder is greater than that of the tangential component T
