The relationship between steel ball wear resistance and ore characteristics.

1. Ore particle size. The coarser the feed, the more intense the impact and friction of the grinding balls, and the higher the loss. Fine ore is mainly ground, and the loss is relatively low.

2. Ore hardness. Hard ores, such as quartz stone, will accelerate the peeling off of the surface of grinding balls. Soft ores, such as limestone, wear out more slowly.

3. Ore density. High-density minerals, such as magnetite, have high grinding resistance and the grinding balls are prone to fatigue and fracture. Therefore, the toughness of the grinding balls needs to be increased

4. Ore properties. Sulfur-containing and acidic ores can corrode the surface of grinding balls. Therefore, high-chromium balls of Cr15 or above should be selected to resist corrosion.

Fifteen years of experience have proved that only by dynamically adjusting the material and size ratio of grinding balls according to the characteristics of the ore and regularly replenishing the balls can costs be reduced and efficiency be increased. Follow Dexin to learn more about grinding balls.
