01
Forged Steel Ball
Forged and heat-treated for impact performance and low crushing rate.
Grinding Media
Forged and cast steel grinding balls selected by diameter, hardness, chemistry and mill operating conditions.


Product overview
Ball mill steel balls are the grinding medium that transfers impact and friction to the material. The original page distinguishes forged steel ball and casting steel ball for cement plants, power plants and mineral processing mills.
Selection should compare mill diameter, feed size, target fineness, impact duty, liner system and acceptable breakage and wear rate. AGICO can quote a graded ball charge rather than a single diameter when operating data are supplied.
