Forged 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.
