ABSTRACT

Pellet and Briquettes are becoming of increasing importance and this is attributed to the variety of purposes which are used as cheaper, portable, more effective variation of their source materials and can be produced by using densification equipment. The cost of these densification equipment can be relatively expensive, thus the need to produce them locally arises. There is also an avenue for modification which makes the locally fabricated pelletizer better than the imported pelletizers. The augers are detachable from the shaft thus creating an opportunity to vary the screw configuration. The interchangeability of the pelletizer also reduces the cost of replacement of the shaft as only the augers can be replaced. The machine was designed and fabricated based on component design consideration using mild steel as a major component which is a readily affordable and available. Preliminary evaluation of the pelletizer yielded a Pelleting Efficiency of 53.69% and a Percentage Recovery of 54.87%
