Grinding and flotation, one system
Products
Grinding Media
Three media families covering primary, secondary and fine grinding. Typical applications are listed for each, but the right media depends on the ore, the mill and the grinding duty, so selection is made per application.
Grinding Media Product Range
Three media families, from primary to fine grinding
Forged, high chrome and ceramic media for SAG, ball, regrind and stirred mills.
Forged grinding media
Forged steel balls for high-impact and general grinding duties, from large SAG top-up sizes down to regrind.
High chrome grinding media
Cast high-chromium balls for abrasive grinding in ball and stirred mills, where wear resistance matters more than impact strength.
Ceramic grinding media
Ceramic beads for fine and ultrafine grinding in stirred mills.
