Bulk Density 2.3g/cm3 Ceramic Blasting media B60 for stainless steel
& alu alloy surfaces finish
DESCRIPTION
Ceramic blasting media also called ceramic micro beads, is a zirconia-based blasting media produced by
melting process, ZrO2 62-65%, with good roundness and good elasticity, no dirt adhesion and easy to clean
after sandblasting, suitable for the treatment of stainless steel surfaces in for instance the food and
pharmaceutical industry.

PRODUCTION PROCESS
FEATURES
Our ceramic beads is of top quality in China, and has below features
1) Imported raw materials, High quality ceramic beads
Use Australia imported high-quality raw materials to produce ceramic beads, high hardness, good elasticity and higher service life.
2) Independent research and development
Complete product testing equipment and complete independent intellectual property rights, as well as independent laboratories and university cooperative laboratories in Beijing and Shijiazhuang.
More importantly, we have years of continuous improvement in R&D team.
3. Better cleanliness and sizes more concentration
We have our own particle sizes distribution standard, with more concentration granules and can screen as per clients’ requirement.
4. High hardness, long life and good elasticity
The hardness of ceramic beads is high,and the deformation is small.
The hardness of ceramic sand can 700 HV, it ensures that ceramic bead can be shot peened for high strength and high strength structural parts. Small deformation ensures that the shape of the projectile does not change during impact, and the spherical shape of the ceramic sand improves the quality stability of the shot peening of the part.
APPLICATIONS
Ceramic blasting media is very suitable for stainless steel products which have to have a high cosmetic value, for example, the treatment of stainless steel surfaces for instance the food and pharmaceutical industry.
Ceramic beads are much better and easier to clean compared with glass bead blasting.
By subsequently ceramic bead blasting, a uniform satin shine finish of the surface can be obtained.
Advantages of ceramic beads:
Starting with a pre finished surface or cold rolled 2B, and depending on the surface treatment, the following roughness (Ra) can be achieved approximately:
Ceramic bead blasting: 2.0 – 0.8 μm
Glass bead blasting: 3.0 – 1.5 μm
Pickling: ~ 0.5 μm
Mechanical Polishing: 5.0 – 0.05 μm
Suitable sand blasting machine:
Manual sand blasting machine, Automatic sand blasting machine,
Open type series of sand blasting machine, and Blasting room series.
