Grinding Media Steel Ball
Grinding media steel ball, your best choice to reduce ball consumption 15-20% than before. Our supply ball size: 25mm to 125mm. Annual total supply capacity: 60,000 tons.
Introduction：
Grinding Media Steel Ball is a common term used for steel balls produced by (hammering/stamping) forging or cross-rolling methods. Jiangyin Dongbang Steel Ball Machinery Co.,Ltd offers forged steel grinding balls in various sizes, ranging from 20mm to 125mm. We can also produce other sizes according to customers' requirements.
After production, the steel balls are heat treated to increase their hardness. In order to change their microstructure, our forged grinding balls are quenched and tempered under conditions specifically designed for each specific alloy.
Jiangyin Dongbang Steel Ball Machinery Co.,Ltd's steel balls are used in mineral processing SAG and ball mill operations to achieve minimal wear and breakage rates.
Several factors influence the mechanical properties of forged grinding balls. Our quality control team carefully inspects all shipments before loading. For material test certificates and any other required information, please feel free to contact us.
