Zirconium oxide grinding beads are produced from micron-sized and sub-nanometer zirconia and yttrium oxide, suitable for ultrafine grinding and dispersing of tough and highly viscous materials where contamination-free production is required. Along with appropriate grinding system, grinding beads play a critical role in increasing grinding efficiency and prolonging service life of the grinding system. With over 19 years of experience in the field, Longly knows that good sphericity and wear resistance will determine the quality and efficiency of the product in addition to the density and size of grinding beads.
L65 Zirconium Silicate Grinding Beads This grinding bead is produced from zirconium silicate particles with low wear property, is an economical grinding media suitable for grinding of medium and low viscosity materials.
L80 Cerium-stabilized Zirconium Oxide Grinding Beads The grinding beads are of a high density and hardness, suitable for grinding and dispersing of hard-to-disperse materials.
L95 Yttrium-stabilized Zirconium Oxide Grinding Beads The grinding beads are acid and alkali-resistant spherical particles with high purity, high strength, and high density, suitable for high value-added products.
