Grinding steel ball

Oriental Grinding Media produces grinding steel balls from high‑grade carbon steel that meet demanding wear requirements. The product line spans diameters from 20 mm up to 150 mm, allowing selection for both laboratory mills and large‑scale grinding circuits. The balls are heat‑treated to reach a hardness of 60 - 65 HRC, which provides the impact resistance required in mineral processing. ISO‑certified production processes are cited, confirming adherence to recognised quality management standards.

Industry practice usually limits diameter deviation to ±0.04 mm for these sizes, a tolerance that helps maintain mill balance. A typical surface finish of Ra 0.25 µm is applied to reduce friction and energy consumption. The material density is about 7.85 g cm‑3, used by engineers to calculate charge volume. Standard bulk packaging includes 1‑ton poly‑ethylene bags or steel drums, which simplify handling on site.

These balls are employed in cement grinding, metallurgy and ceramic powder grinding where consistent media performance is crucial. Oriental Grinding Media indicates that shipments can be organised on FOB or CIF terms, with payment via L/C or T/T. Prospective buyers should verify the minimum order quantity and any additional testing certificates directly with the supplier.
