  Description:
  zirconium silicate beads are shaped in electrolyte solution and hardened at a high temperature in kiln. Compared to electrofused zircon beads and the similar others,they have homogenous microstructure and no air pockets. This give them 1/2 lower beads wear rate than the others. The middle density and hardness features are suitable for grinding slurry in viscosity from low to middle.The small sizes are the high quality blasting and peening media.
  
  Features:
  High crushing strength: Homogenous micro structure ~ Lower bead wear;
  Higher gravity: Special composition ~ Higher density ~ Higher efficiency.
  High sphericity: 96% sphericity ~ Better fluid ~ Higher through put;
  No air pockets: Free from fragile beads ~ Easy change colors;
  Smooth surface: Deeply polished surface ~ Easy wash; lower wear rate of contacted parts of mills;
  Narrow sieving: 0.1mm tolerance ~ Lower bead wear; narrower distribution particles of grinded material.
