What is a Ring Die Pellet Mill?

Ring die pellet machines are another popular type of pellet mills. In contrast to flat die pellet machines, those with a ring die are more often used to produce wood pellets on a large scale for light industrial and commercial purposes. Ring die pellet machines are not as widespread as those with flat dies due to the increased complexity of the machines and hence, higher costs. As the die's name suggests, the ring die has a wide cylindrical shape and is mounted vertically, rather than flat and horizontally as with a flat die. A surge bin is used to feed biomass materials through a variable speed conditioner before being distributed through the pelleting machine door. A screw auger is useful at this last step in centering the materials in the pelleting machine chamber.
