Influence Of Steel Ball Diameter On Grinding Steel Balls (1)

(1) Affect the productivity of the mill. When the ball diameter is too large, the productivity is reduced due to the small number of blows and the small grinding area. When the ball diameter is too small, the productivity is reduced due to insufficient striking force. The precise ball diameter can greatly increase the productivity of the mill. When the ball diameter is changed from too large to accurate, the use factor value of the mill according to -0.074mm can be increased by 15%~40%.

(2) It affects the uniformity of particle size distribution of grinding products. Too large ball diameter makes the number of blows less, resulting in more coarse grades that are not finely ground. Therefore, when the ball diameter is too large, the particle size of the product is uneven, too coarse and too crushed, which is not conducive to selection. The test shows that when the ball diameter is adjusted from too large to accurate, the maximum particle size and average particle size of the grinding product are reduced, and the excessive crushing is also reduced by 3%~4%. The particle size of the product is more uniform, and it is easy to increase the particle size in the middle. Beneficial for beneficiation.
