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.
