The BFS Screw Feeder receives the material from the mixerhopper and transfers it to the BVS Vertical Screw Conveyor. The BFS Screw Feeder is a discharging equipment provided with optional inlet spouts which are pre-engineered to suit the most commonly used mixers on the market. The BVS Vertical Screw Conveyor receives the material from the BFS Screw Feeder through a tangential or frontal discharge port. The BVS Vertical Screw Conveyor lifts the biomass to an appropriate height where it feeds it into the BIS Injector Screw.
