In the context of mineral processing, grinding bodies used in a cylinder mill are typically materials that provide the necessary weight and hardness to disintegrate ore through tumbling action. Common materials include:
- Flint stones1
- Iron balls1
- Steel balls1
In autogenous mills, no external grinding bodies are used, as the coarser ore serves to grind the finer fractions. Conversely, semiautogenous mills utilize a small addition of grinding bodies, which are usually metal spheres, to assist in the process.1
