1. **Mining**: Grinding balls are commonly used in the mining industry to crush and grind ore into smaller particles. They are placed inside grinding mills, such as ball mills or SAG (Semi-Autogenous Grinding) mills, where they help break down the ore into smaller, more manageable pieces for further processing. 2.
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].
Forged steel grinding balls are utilized in ball mills, where they serve as grinding bodies, facilitating the reduction of material size through impact, abrasion, and crushing. These balls are produced from high-quality iron and steel, ensuring durability and performance in demanding industrial applications.
