The diagram delineates the sequential procedure involved in the production of wood pellets, which are utilized as a heating source for buildings.
Overall, the process comprises several distinct stages, beginning with the acquisition of sawdust and culminating in the packaging of the final product.
Initially, the process starts with the delivery of sawdust from sawmills, which serves as the primary raw material. This sawdust is subsequently processed in a hammer mill, where it is transformed into fibers of uniform length. Following this, moisture is introduced to the fibers through the application of steam, which is vital for the subsequent pelletization step.
The next phase involves the compression of these dampened fibers through a pellet machine, where they are shaped into pellets. Once formed, the pellets undergo a cooling process to stabilize their structure. Any loose dust is then removed through vacuuming before the finished pellets are packed into bags weighing 18 kilograms (approximately 40 pounds) for distribution. Notably, these wood pellets produced by this method are suitable for use in both pellet stoves and pellet furnaces.
