20-150mm grinding steel balls cast steel balls and forged steel balls chemical composition as client required high hardness 60-68hrc,low consumption 30kg/per ton cement, low berakage 0.5% max. telephone 0086-13933429302 address baiguantun town,fengrun district,tangshan city,china.
the tight grain structure offers great wear resistance without the need to make products “superhard” we have found that, on a blank hrc 38-42 forged grinder insert wear/wash is about the same as a high alloy hrc 46-50 cast grinder insert. the difference being a hrc 46-50 casting does not have the ductility to handle high impact grinding.

the ball mill grinding ball on the market now can be divided into two kinds according to the manufacturing process: cast grinding ball and forged steel ball, but their wear degree is not the same. due to crushing and pulverizing materials, grinding balls need good abrasion resistance and enough impact toughness, and require steel balls cannot be broken, ball mill grinding balls can be divided into:
grinding cast balls and cylpebs in alloy steel. we supply balls on a wide and complete range of hardnesses, with different hardness profiles, to maximize the grinding performance in wear rate and impact endurance, at a regular wear and with tailor-made alloys according to the mill and milling material needs.
