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
