    The phenomenon of fine grinding in ball mill is closely related to grinding concentration, and the grinding concentration is directly related to the amount of ore. Too large or too small concentration will have a bad effect on the normal work of the ball mill. When the concentration is too large, the flow speed of pulp slows down, and the impact of grinding medium steel ball becomes weak.
