The corresponding relationship between the wear rate of grinding balls in ball milling and the grinding concentration.


1. At low concentrations (< 65%), the slurry has strong fluidity, the direct collision of grinding balls increases, and the impact wear intensifies
2. The optimal concentration (65%-80%) ensures the best slurry buffering effect, uniform wear of grinding balls, the highest grinding efficiency and the lowest loss of grinding balls.
3. High concentration (> 80%), viscous pulp, severe adhesion on the surface of grinding balls, decreased grinding efficiency, and increased abnormal wear.

Under normal working conditions, when processing ores with coarse particle size, high hardness and high density, use relatively concentrated pulp, with the concentration controlled at 75%-80%. For processing ores with fine particle size, low hardness and low density, use relatively dilute pulp, with the concentration controlled at 65%-75%. In conclusion, the grinding concentration directly affects the impact force and wear rate of the grinding balls. Precise control of concentration can appropriately reduce the loss of grinding balls.

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.

Grinding Media Balls 30-140MM Production Project. This video fully shows the whole grinding media ball production process from 30mm to 140mm. From shooting sand to the mold cavity 3-5mm. Then closing the top and bottom mold. Then pouring. Then grinding balls have been produced well.
