Cast Steel Grinding Balls
The ZETAGRIND-SG® grinding balls with a chromium content of 13% are especially suitable for the application in cement grinding (raw material and clinker). The high hardness of 60 to 65 HRc ensures minimum wear rate over the course of use. The ZETAGRIND-SG® grinding balls are normally filled in the second and third compartment of mills for cement and raw material grinding.
