Grinding balls are only one type of grinding media. Grinding media are the means used to crush or grind material (cement, mineral, …) in a mill. Grinding media sorting is performed when the ball load wears out. New grinding balls are then added or full reload is carried out to keep optimum filling degree and hence mill performance.
According to the material to be crushed or ground, grinding media can have
Different forms: grinding balls, boulpebs (cylinders with rounded tops), rods or even beads.
Different sizes: balls (diameters from 10 to 150mm), rods (different length and diameters),…
Different composition (alloy): high or low chromium content for steel and iron balls for example.
Different manufacturing process: balls for instance, can be cast or forged for instance.
