It is consist of perforated cylindrical hole screen, cleaning brush, gearing device, frame and induced draft part. Raw materials get into the screen cylinder through feeding tube, the edge of the screen cylinder is closed. The entire screen cylinder is cantilever supported by main shaft . The screen cylinder is seperated to front and rear parts, the part close to the shaft adopts 20mm*20mm square holes, which makes the granuales get through the screen quickly; while the part close to the impurity outlet adopts 13mm*13mm square holes to prevent large imprities get through the holes and mixed in the grains.
