The self-developed automatic steel grinding ball production line is our qualified product, and it has won Chinese invention patent. It uses electric furnace instead of conventional coal combustion method, and the rotary cutting technique replaces traditional air hammer, thereby improving production efficiency by 30 times or even higher.
On the other hand, by controlling the leading-edge self-developed quenching equipment, high quality steel grinding balls with different hardness levels and mechanical properties could be produced, and they are characterized by high internal and external hardness, uniform hardness distribution, high impact toughness, good wear resistance as well as excellent shape maintenance without breaking apart.
