Wood Pellet Mill Raw Material Types?

                    Straw fuel pellet mill is a special machinery equipment to make sawdust, corn stalks, peanut shells, rice straw, cotton stalks, tree branches, edible fungi waste and cow dung into high-density combustible quality pellets. It adopts the principle of extrusion and friction interaction between the press wheel and the mould, so that the material can be shaped. There is no need to add any additives or binders to the material during processing.

                    The raw material of fuel pellet machine, straw and other materials contain certain cellulose and lignin, and its lignin is the structural monomer in the material, which is a phenylpropane-type polymer compound. It has the function of enhancing cell wall and bonding cellulose. Lignin is non-crystalline, the main part of which is insoluble in any solvent at room temperature, has no melting point, but has a softening point. When the temperature reaches a certain value, lignin softening bonding force increases, and under certain pressure, so that its cellulose molecular group dislocation, deformation, extension, internal adjacent biomass particles engage each other, recombination and compression moulding.
