At this time, the controller controls the granulation motor 5 to work, driving the cutting plate 6 to rotate and cut the raw material for granulation. When the granules fall, the cooling component 3 works to draw air to the granulation surface to cool the granules. Finally, the granules roll out from the ramp at the bottom of the processing box 1.
