SEPR has introduced a new high-density ceramic grinding bead produced from yttria stabilized zirconia powder by a unique manufacturing process. Zirmil(R) ceramic beads offer increased productivity and longer media life for microgrinding paint, printing inks, pigments, dyes, minerals and cosmetics. Zirmil is well suited for use in horizontal mills and particularly in high energy mills. With a density of 5.9, the new beads are 55% more dense than typical ceramic beads. They are produced by the sintering of fine, uniform particle size mineral oxides into a homogeneous and highly cohesive bead structure. The crystollographic structure and chemical composition (93% zirconium oxide) contribute to the beads' outstanding wear resistance.
