Ring Die Pellet Mill

Ring Die Pellet Mill is a popular special design. It owns much more merits than flat die pellet mill. Ring die pellet machine is often used to produce wood pellets on a large scale for light industrial and commercial purposes. While flat die pellet mill applies to home or small scale pellets production. 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 is mounted vertically, rather than flat and horizontal as with a flat die. 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.

Advantages of Ring Die Pellet Mill:
There are two main distinct points of ring die: one is, it generate less wear and tear, since both the inner and outer edges of the roller traverse the same distance; another one is, it is more energy efficient than flat die design. Roller slip during the pelleting process brings extra friction, but this extra friction is an accelerating element in the production of quality wood pellets due to the additional heat.
