the performance characteristics of the ball mill are high production capacity, strong adaptability to the material, high degree of fineness of the material, fine particle size of the discharge, easy to fine grinding, energy saving is more obvious, but the phenomenon of over crushing is serious.
2.more crushing and less grinding, reducing the feeding particle size of ball mill. the larger feeding particle size is, the greater the work done by the ball mill on the ore, which impacts the grinding efficiency. To reach the eligible grinding fineness, the workload must increase. the energy consumption is also increasing.
the complexity of grindability is determined by ore hardness, toughness, dissociation and structural defects. small grindability, the ore is easier to grind, the wear of lining plate and steel ball is lower, and the energy consumption is also lower.therefore, the property of raw ore directly affects the productivity of the ball mill.
