Ring die pellet mill is widely used to make wood pellets in a large scale for light industrial with commercial purposes. [ Ссылка ]
Yet ring die pellet mill is not as widespread as flat die pellet mill 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 centering the materials in the pellets machine chamber.
