Product Description

1. Product Description of Ceramic Beads

Ceramic beads is one round solid blasting media, It has the outstanding features of high hardness,good

elasticity,low breakdown rate,especially suitable for the metal surface finishing.


It selects the high-quality zircon sand as main raw material, then fused in arc furnace at high temperature,

then screened into different micro-beads by process of cooling, selection,electromagnetic,packing.


Ceramic beads is one clean and high efficient blasting media,which is widely used to replace glass beads

due to its outstanding features of high hardness and low break down rate.

Different Applications

Blasting media,

widely used for surface finishing,which matches most types of blasting equipment

Grinding media,widely used for grinding&dispersing of low or medium viscosity slurry,which matches sand mill.


And they have different applications: ceramic beads for blasting application,while zirconium silicate

beads for grinding & dispersing application.
