Wood Pelletizing Process of Flat Die Pellet Mill
Wood pellets are produced by compressing the biomass material which is first grinded to provide a uniform dough-like mass. Then the mass is fed to a pelletizing chamber and formed pellets through a die with holes of the required size. The high pressure of the press makes the temperature of the wood increase greatly and the lignin slightly forms a natural "glue" which is a substance that holds the pellet together. The size of pellets is generally kept to be about 6mm diameter and 25mm length in the form of a cylinder. Of course, we can customize dies with different die holes.
