25KG Wet or Dry Airblast Ceramic Bead Blasting B20 B30 B40 for
Metal Surface Finish
1. Product Description of Ceramic Beads
Ceramic beads is one clean and high efficient blasting media,it
selects the high quality imported zircon
sand as main material,then fused in high temperateure over 2500
degrees, finally made into different
microbeads.
The unique crystal structure of ceramic beads ensures its high
hardness and good impact resistance,
its smooth surface and stable chemical inertness ensures little
damage to the blasting machine and
zero contamination to the treated workpieces.
Ceramic beads has lower break-down rate,which will improve the
blasting efficiency and easy to achieve
one more consistent and shinny blasting effect.
So ceramic beads is widely used in blasting application,especially
suitable for metal surface finish.

3. Main Applications of Ceramic Bead Blasting
Surface cleaning for the inner and outer walls of stainless steel
pipes;
Surface preparation before electroplating,anodizing to achieve one
certain roughness,then improve the
surface adhesion;
Surface finish for light alloy such as magnesium alloy,aluminium
alloy, titanium alloy to restore the metal
color;
Surface cleaning for electronic parts,heat-treated parts,welded
parts to remove the surface burrs and weld
joint;
Shot peening for aviation and automotive industries such as
aircraft landing gear and automotive gears to
eliminate the stress and improve the fatigue strength and service
life.
4. How to judge the quality of ceramic beads?
Seen from the appearance,good ceramic beads has higher
sphericity,mostly beads is in round shape, little in strip
shape,which is visible by naked eyes.
Seen from the gloss under the microscope, good ceramic beads has
good shinny gloss.
Judge from the cleanliness,good ceramic beads can quickly sink into
the bottom of the container,while the water is still clear.
