Features

  • Size: Mid-size ball grinding media are available in sizes from 2.0” to 4.0” or 50mm to 105mm.
  • Chemistry: The chemistry ranges for each diameter ball to optimise microstructure and hardness after appropriate heat treatment.
  • Surface and volumetric hardness: The wear resistance and the impact breakage resistance of the balls depend on the microstructure developed in the steel by carefully selected heat treatment variables, specifically designed for each alloy.

Molycop’s mid-size ball range is primarily used for secondary ore grinding operations in which high wear resistance and impact breakage resistance are the main ball attributes required.

Our grinding balls use high-carbon alloy steel bars as the raw material and are then subject to special bar heating, forging and heat treatment processes to obtain optimum wear and impact resistance.
