Sawdust or wood dust is a byproduct of cutting, grinding, drilling, sanding, or otherwise grinding wood with a saw or other equipment. Sawdust as one of the best raw materials for fuel pellet production is abundant world widely. The finished sawdust pellet has the advantage of high caloric value ,easy transportation .Among of them ,the caloric value is decided by the lignin content ,more ligin it has ,more higher caloric value it is ,and this point do matter the price of pellet .
Sawdust pelletizer is used to press sawdust into pellet .
When the sawdust goes into the pelletizer chamber of the sawdust pellet machine, the lignin of the sawdust will be heated up to 120-130 ℃ by the heat produced by the running sawdust pelletizer and by which the lignin will be plasticized and binds the pellets together to help to mold the pellets. The pellets are molded by being pressed through the pellet dies of the sawdust pelletizer ,and then are cut off by the cutter with the desired length. During the pelletizing, the binder may be needed to improve the pellet strength and durability.
