Many types of grinding media are suitable for use in a ball mill, each material having its own specific properties and advantages.

Cast Grinding Steel Balls - 911Metallurgist

However, not many high Cr balls are used in primary grinding because the improvement obtained in wear resistance relative to steel, typically 25 – 30%, is not enough to offset Its higher cost. In primary ball milling, wear speed is largely independent of ball diameter and mill volume.

Grinding Mills - 911Metallurgist

Double Stage Ball Mills Occasionally, the liberation requirement for an ore requires very fine primary grinding. Usually, the most expeditious way to accomplish this objective is by double stage ball milling. Both mills are usually operated in closed circuit with separate classifiers.

Ball Mill - an overview | ScienceDirect Topics

Ball mills tumble iron or steel balls with the ore. The balls are initially 5–10 cm diameter but gradually wear away as grinding of the ore proceeds. The feed to ball mills (dry basis) is typically 75 vol.-% ore and 25% steel. The ball mill is operated in closed circuit with a particle-size measurement device and size-control cyclones.
