There are three types of grinding media that are commonly used in ball mills: • steel and other metal balls; • metal cylindrical bodies called cylpebs; • ceramic balls with regular or high density. Steel and other metal balls are the most frequently used grinding media with sizes of the balls ranging from 10 to 150 mm in diameter [30].

abrasiveness, of the ore can vary, resulting in inconsistent grinding behaviour. The addition of steel grinding balls rectifies this situation. This approach is then termed semiautogenous grinding and the total amount of balls in these mills ranges between 5 and 10 percent of the volume. Figure 5 SAG Mill picture and general shape

The breakage and liberation of minerals are the key to fluidized mining for minerals. In the ball milling process, steel balls function as not only a grinding action implementer but also energy carrier to determine the breakage behavior of ores and the production capacity of the mill. When ground products present a much coarse or much fine particle size distribution, the separation process ...

In the grinding mill, the ore blocks sized >100 mm function as grinding medium. The ore particles smaller than 80 mm but bigger than 20 mm have poor grindability and they cannot be easily ground by big lump ore, so such material is usually called "hardtogrind ore" or "hard rock." To crush the hardtogrind ore, sometimes steel balls ...
