Generates Glass Product with No Sharp Edges

The Andela GPT-1HD Glass Pulverizer system recycles waste glass at a rate of 3-5 tons/hour into reusable sand and gravel sized aggregates, separated from trash.

With precision loading into the Andela Surge Hopper, glass and waste travels up the Andela Conveyor into the GPT-1HD pulverizer and then to the Andela Rotary Trommel without any pre-sorting required. Oversized non-glass contaminants such as paper labels, metal caps, corks, etc. remain intact for hands free removal during screening. Placed either over bunkers or on legs, the end result is the same – your sand and gravel are separated and safe to handle.

  • Pulverizer / trommel combination unit provides a condensed layout ideal for those looking to optimize recycling capacity within a limited space.
  • Machine design features access doors with bolt in replacement liners and hammers for hassle free maintenance and service.
  • Dual screening trommel size separates glass sand and gravel product for potential resale.
  • Material uses include: backfill, drainage, filtration media, glassphalt, decorative landscape mulch and so much more!
  • The GPT-1HD Glass Pulverizer can also be purchased as a single unit.
