SPECIFICAION:
65 ZirconiumSlicate Beads
The Zirconium silicate beads is produced by choosing imported zircon sand as raw material, then finely grind and rolled to beads using fully automatic pressure rolling process and processed through high-temperature sintering and phase determination process. It has the characteristics of high compressive strength and low wear resistance, and is widely used for ultrafine grinding of products such as calcium carbonate, kaolin, titanium dioxide, coatings, inks, etc.
