The aforementioned process diagram depicts the manufacturing of wood pallets which are used as a source of fuel to heating buildings.
At first glance, it is evident that there are total seven stages during the process while the delivery of sawdust from a sawamill is a initial step and packaging the pallets for sale is the last step.
To begin with, sawdust is transported from a sawmill and fed into a hammer mill. In this machine, the sawdust is hammered into fibres of a uniform length. The fibres are dampened with stream in order to improve their consistency and prepare for the next stage. following this ,the treated fibres are forced through small holes in a pallet machine, where they compressed and formed into pelletes. Once the pelletes have been produced, they are cooled to increase the durability and stability. After cooling, any loose dust remaining on the pellets is removed by a vacumming process.
In the final stage, the finishes pellets are packed into 18- kilogram (40 pound) bags and prepared for commercial sale. The resulting product can then be used effeciently as afuel source in both pellet stoves and pellet furnaces.
