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
