ER120 - The original ceramic bead
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.
