Pelleting is a process to press finely grinded biomass material into firm pellets of a required shape and size by extruding it through a metallic ring die. The raw material is fed into the ring die pellet press through a conveyor and then conveyed into a rotating ring die by a feeder auger. Finely grinded biomass material will be pressed into ring die through two rotating press rollers. The resulting pressure compresses the material and extrudes it through the holes in the die.
