Wood pellets are a kind of fuel using for heating buildings. The diagram below illustrates the process of manufacturing wood pellets using used in either pellet stoves or pellet furnaces. As can be seen, there are several steps for making the pellets after arriving to at the factory, including hammering, wetting dampening, molding, cooling, sweeping, and packing.
According to the diagram, after gathering sawdust from a sawmill, it is sent to the factory. Firstly, it is converted into fibers in of the same length by hammering in a hammer mill. Then, in the next step, they are wetted dampened with steam (in order) to be flexible and to be ready prepare for pushing pressing in to through holes in a pellet machine to be shaped into pellets. After molding them, they are required to be cooled. Then after(wards), they are swept. In the last step, they are ready to be uniformly packed in the same weight as 18 kilo pellets weights which are distributed for selling sales {or retail}.
