Glass Beads – GP

In the production of glass granules, soda-lime glass is crushed and pre-sifted. The crushed glass is then shaped into beads by means of a heat stream in a furnace. Glass beads are a mineral blasting medium.

Applications:

Reusable abrasive
Polishing
Compacting
Blast-cleaning

Blasting systems:

Pressure blast systems
Injection blast cabinets
