China wholesale colloidal silica Manufacturer, Supplier, Factory

Cast steel balls are wear-resistant grinding media manufactured via high-temperature metal mold casting and professional tempering heat treatment. We supply full series including low chrome, medium chrome and high chrome cast steel balls with diameter ranging from 10mm to 150mm. The product features uniform internal hardness, ultra-low breakage rate, outstanding abrasion resistance and stable roundness without deformation during long-term grinding. High chrome cast steel balls reach HRC 56–62 hardness, medium chrome HRC 47–55 and low chrome HRC 45–52, perfectly matching dry and semi-dry ball mill working conditions. Widely applied in cement plants, mineral processing mines, thermal power stations and chemical grinding workshops. As a direct Chinese manufacturer, we support bulk tonnage supply, customized chrome content & sizes, and provide complete ISO certification and material test reports to global industrial buyers with competitive factory prices.
