The experimental results showed that the Abbott-Firestone curve can evaluate the lifter surface topography. The wear rate of the lifter specimen is increased first and then decreased with mill speed and grinding media size. Increasing ball filling will increase the wear rate, and the grinding media shape of ball has a maximum wear rate. The ...

3. Conclusion. This article aimed to review and discuss the available literature on the wear of grinding media. The consumption of the grinding media represents an expressive part of the grinding operational costs, reaching up to 50% of it. During grinding, a combination of abrasion, corrosion and impact results in wear of grinding media.
Grinding Media is widely used in cement, metal mining, power plant and chemical industry etc. The hardness reaches up to 66HRC(the surface and core hardness tolerance could be controlled within 2HRC),which makes the optimum wear resistance against abrasion and corrosion.

High chrome grinding media in cement mill. HRC60-65.
maximize this rate. The mill grinding efficiency can also be calculated by taking the ratio of the mill grinding rate over the material's grindability as measured in the lab. Mill percent solids optimization has thusly been achieved (McIvor et al., 2000). For media sizing, maximizing the mill grinding rate on a given ore is equivalent
less than 10 pct of the wear of grinding media in commercial mills. A of corrosion rates for various types of grinding media shows that alloying elements and electrochemi cally active inclusions in steel affect the corrosion behavior of the media. 'Group supervisor. 'Research <",,",'
