The Original Ceramic Bead

ER120 is a fused ceramic grinding bead based on zirconium silicate. Available in two grades, ER120 A is well suited to large volumes and vertical mills, while ER120 S is an enhanced version designed for use in horizontal mills. ER120 is an ideal replacement for glass, improving productivity and cost effectiveness. The polished surface of ER120 ensures low mill wear. 

Zirconia and silica composite material

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.
