• ER120 and Rimax beads are two grades of middle range density beads that often remain the best milling solution in conventional milling equipment. They are the best alternatives to glass beads.

     

    ER120 - The original ceramic bead

    ER120 is a fused ceramic grinding bead based on zirconium silicate. Available in two grades, ER120A is well suited to large volumes and vertical mills, while ER120S 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.

    RIMAX - A dependable milling solution

    Rimax is a durable zirconium silicate bead recognized as the standard in many milling processes. It is recommended when large bead sizes are required or in aggressive environments such as in basket mills. Rimax is the product of choice in most traditional applications.

    RIMAX also exists in a higher density version, RIMAX HD, with improved wear performance and durability in severe conditions.

    Silica and Zirconia composite material
    ER120 - 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.
