[0002] Dust-free feeding station refers to the manual unpacking of small bag packaged materials. During the whole unpacking process, dust is removed by filters and dust removal fans, and dust will not leak out. It is suitable for 0-50kg small bag packaged powder and granular materials. It is a new product developed on the basis of extensive absorption of similar foreign products. At present, it is the domestic advanced, ideal and complete vacuum conveying equipment for powdery materials and powder-granular mixtures. It not only reduces the labor intensity of workers, but also solves the problem of dust overflow during feeding. It is the preferred equipment to promote clean and civilized production.
