Reasonable addition of steel balls in the long-term operation process, the mutual grinding between the steel balls and ore of ore milling plant will cause a certain degree of wear of the steel balls, resulting in the change of the proportion of steel balls of different sizes, resulting in the change of the fineness of grinding products, and then affect the grinding efficiency of ore milling plant.

Therefore, the operators of ore milling plant need to regularly check the condition of steel balls and reasonably add steel balls to ensure the stable production of ore milling plant.

Strictly control the grinding concentration of ore milling plant. Generally, the grinding concentration will affect the pulp specific gravity, pulp fluidity and the adhesion of ore particles around the steel ball.
