The Competent and Cost-Effective Mining Bead
Minerax is a composite bead based on a unique combination of alumina and zirconia materials. It is an ultra-tough bead with class-leading roundness and surface finish. Minerax is a proven product in the mining industry, delivering excellent performance in ultrafine grinding applications.
Manufactured by the fusion of oxides, ER120 combines the benefits of ceramic zirconia and glass. When cooling to room temperature, the melt solidifies with a specific composite material structure made of a zirconia monoclinic phase dispersed in a glassy silica phase.

Grinding of natural ores is tough for milling media, resulting in high wear of beads. Minerax has an extended media lifetime and a controlled wear pattern. This provides a stable working mix and low mill wear, increasing productivity and reducing costs.
