In the grinding operation, why shouldn't the large grinding balls in the ball mill exceed 70%?

According to the principle of having fewer balls on both sides and more in the middle for grinding balls, the proportion of large grinding balls in the internal grinding balls of the ball mill is generally 30%-40%, medium-sized grinding balls account for 30%-40%, and small size grinding balls account for about 30%. As the large grinding balls wear out, large grinding balls need to be added regularly, but it is necessary to ensure a reasonable proportion. If the proportion of large grinding balls in the internal of the ball mill exceeds 70%, it will lead to a reduction in the effective area of the overall grinding balls, and many grinding balls will not be able to perform their functions. The grinding efficiency of the ball mill will also naturally decrease. For any problems with the grinding balls, please contact us at any time.
