Ring Die Pellet Mills are widely used to a large scale wood pellets production line for light industrial and commercial purposes. They are not as widespread as those with flat dies due to the increased complexity of machines and higher cost. As the die's name suggests, the ring die has a wide cylindrical shape and it is mounted vertically. A surge bin is used to feed biomass materials through a variable speed conditioner before being distributed via the pelleting machine door. A screw auger is useful at this last step of putting the materials in the pellets machine chamber.
