The given flow chart describes the process of making wood pellets from sawdust for the purpose of insulating buildings.
Overall, this includes seven different steps starting from the collection of sawdust to the packing of pellets in designated bags.
First of all, the raw material, sawdust is transported from sawmill to hammer mill where it is modified into fibres of equal length. Thereafter, those fibres need to be dampened with steam. Subsequently fibres are passed through a pellet machine resulting in formation of pellets.
Next step involves cooling those pellets following which the dust particles are separated by vacuum cleaning. Last step is packing, when the newly manufactured pellets are stacked into bags which weigh 18 kilograms and is set for sale.
