Ring Die Pellet Mills

Ring Die Pellet Mills Instruction:

Ring die pellet mills are another popular type of pellet mills. In contrast to flat die pellet mills, 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 mills 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.

Advantages of Ring Die Pellet Mill:

There are two main advantages in using ring die pellet mills. First, ring die pellet mills generate less wear and tear since both the inner and outer edges of the roller traverse the same distance. Second, ring die pellet mills are more energy efficient the flat die design. Roller slip during the pelleting process brings extra friction, but this extra friction is a good element in the production of quality wood pellets due to the additional heat.
