Min 90% Roundness Ceramic Bead Blasting Media B170 B205 B400 B505
for Metal Surface Finish
1. Product Description of Ceramic Beads
Ceramic Beads,glass beads,steel shots are all round solid blasting
beads. All of them plays an important
role in blasting applications,while ceramic beads is able to
replace glass beads and steel shots,since its
medium density,which can make up the upper and lower blind area in
blasting process.
Ceramic beads also can replace glass beads where one clean and
bright blasting condition is required or
replace steel shot where one ferrous contamination is prohibited.
It is one clean and popular blasting media in industry.
