1. Product Description of Ceramic Beads Grinding Media
Zirconia Ceramic beads selects the high quality zircon sand as main
raw material, then fused in arc furnace under high temperature over
2000 degrees, its unique internal crystal phase provides its strong
hardness and impact resistance. It is one round solid blasting
media,with good sphericity and elasticity. Suitable for mental
surface treatment,and various sandblasting machines.

Special Specification can be customized |
Workpiece | Blasting media | Consumption Monthly | Dust | Dust disposal cost |
Die-cast aluminum workpiece | Glass beads 60# | 7 Tons | Much | High |
Ceramic beads B60 | 0.2 Tons | Less | Low |
So seen from above,Ceramic sand not only save monthly consumption
cost and improve the work efficiency, ceramic beads has higher
hardness, higher density,little dust pollution,which can be
recycled in multiple, so ceramic beads are better grinding media
than glass beads.
3. Main Application of Ceramic Beads Grinding Media
1)3C metal Products and accessories surface finish and cleaning;
2)Metal finish for aluminum parts,stainless steel parts,light
alloys...
3) Surface blasting for rubber parts,plastic parts;
4) Mold-cleaning for glass-bottle,tires,die castings;
5)Surface preparation before anodizing,electroplating;
4. Storage, Package and Usage of Ceramic Beads
Ceramic beads should be stored in dry clean and ventilated indoor
environment;
Kindly remind to wear masks and protective suit when using ceramic
beads;
Normal package:25kg round barrel+pallet;
since ceramic beads need the wind to be recycled in the blasting
process, so when using ceramic beads at the first time, please
kindly open 1/3 to 1/2 vest of dust collector.
