Take a look at what our customers had to say about the GlenFarrow auto-feed!

Stage one

Stage one

The 6m³ hopper is filled with woodchip.

  • 6m³ capacity
  • All steel construction

The hopper auger is fixed to the bottom of the hopper and moves woodchip up to the top of the rotary valve.

  • High torque double worm gear motor
  • 6mm welded auger flights for strength and longevity
  • Bespoke auger design for fast and efficient movement of wood chip
Stage three

Woodchip falls vertically into the rotary valve which acts as a permanent fire break.

  • Hardened steel blades
  • Oversized woodchip is chopped down to size
  • Solid steel shaft
  • High torque double reduction helictical pre-stage and worm gear box motor
  • Fully powder coated outer for weather protection

  • High temperature and abrasion resistant
  • Graphite seal and fast acting pneumatic actuator
  • Close protection by means of an electrical limit switch
  • Stainless steel knife blade
Stage five

Stage five
