Product Description

Ceramic beads blasting finish  B20,B30, B40, B60, B80, B100, B120, B150, B170, B205




Ceramic beads  is made of imported zircon sand as the main raw material, and is produced by high temperature smelting above 2000 degrees. Particularly suitable for metal blast cleaning, surface finishing and pretreatment before coating.

Ceramic beads has a fine microstructure, so it has very good impact strength and toughness, high hardness and surface smoothness, can be recycled repeatedly, and has a high utilization rate, which is 15-20 times that of glass beads.

B20-B505 has a wide range of particle sizes, strong optionality, and can be matched with various types of sandblasting machines.

  • High impact resistance and round beads, not easy to be broken. The broken rate of ceramic beads is around 1%.
  • Low dust generation, friendly to the environment and worker’s health.
  • Matte Metallic luster, no polishing reflective.
  • No metal pollution.


Pressure blast systems
Injection blast cabinets


Surface finishing:


Achieve smooth but non-reflective matte visuals effects


  • Deburring of machined parts;
