The relationship of grinding ball diameter with the grinding efficiency

The steel balls in the ball mill have different sizes, which will have different functions. The bigger size steel ball has a strong impact rate and is suitable for crushing large and hard materials, but the contact area is small and the crushing efficiency is limited. The number of small steel balls is large, and the contact area is large, which is suitable for grinding fine particle materials, but the impact force is weak, and it is difficult to crush large materials. Choose the right steel ball size to maximize the effect. The material hardness is large, the particle size is coarse, and the steel ball of larger size is selected to improve the impact force and speed up the crushing speed. The material hardness is small, the particle size is fine, the steel ball of smaller size is selected, the contact surface machine is increased, and the grinding efficiency is improved. Dexin recommended the use of multi-stage ball matching scheme, the different sizes of steel balls in proportion to use, both to ensure the impact, but also to improve the grinding efficiency, meet to the best grinding effect.
