Blasting media Difference of Glass beads, Ceramic beads and steel
shot in sandblasting
DESCRIPTION
Ceramic blasting media is also called Ceramic beads, ZrO2 62-68%,
Bulk Density 2.3g/cm3, HS code 691410.
Ceramic beads is of high impact properties coupled with good
hardness. It is spherical and of smooth surface,
much lower roughness than glass beads and steel shot, leading
beautiful satin shine finish on the blasting work
piece and easier to clean.

FEATURES
1. The density of the ceramicbeads is between glass beads and steel shot, and
with high hardness, can be used to fill the upper and lower limit
of the strength of glass beads and steel shot.
2. The ceramic beads is light, but its hardness is high, which is very suitable for the strengthening and forming of metal
blasting sand such as titanium alloy, aluminum alloy and high
temperature alloy.
3. Ceramic beads is not deformed in the process of circulation and wear low, which can ensure the consistency of the surface sandblasting effect during mass production.
4. Ceramic beads is spherical and has smooth surface and low loss of equipment.
5. Ceramic beads has a wider range of particle size and can be used
in matching with various types of sandblasting machines to meet more application requirements.
