To better serve you, we would like to discuss your specific requirement, Please Contact Us for a quote.

MSE Supplies offers different types of cast steel grinding balls, with sizes ranging from 15mm to 130mm. Cast steel balls are produced by steel molds or sand box molds, with pouring ports, blisters and ring belts on the surface. As a primary grinding media, it is widely used in Cement Plants, Mines, Power stations, Chemical Industries, Coal mill and so on. Due to the high Cr content,  the relative wear rates show a performance improvement of 25 – 30% and in the corrosive environments with low abrasion, the improvement could become 50% or more as compared with forged steel.
