[0002] Tobacco leaves are the main raw material in the tobacco industry. Tobacco leaves need to be threshed and re-roasted during processing to separate the tobacco leaves and stems. Tobacco leaves are in the form of sheets, and the stems are long and thin. Screening equipment is needed to separate the two. Pour both into the equipment, and the stems can fall down from the mesh. The tobacco leaves, due to their larger diameter, will remain on the mesh surface, thereby achieving the screening of the tobacco leaves and stems.
[0003] When adding materials, it is easy to add too much material, which will cause the tobacco leaves to accumulate on the surface of the screen. At this time, the filtering speed of the screen holes is certain, which will cause the tobacco leaves to be blocked in the screen holes, and impurities cannot be removed.
