Drum Iris

During the sampling, packaging and feeding process of HAPI powder materials in the barrel system, whether it is in accordance with EHS safety regulations or in a highly sealed working condition, the barrel iris structure effectively solves this problem (the iris structure is composed of elastic rubber, and it adopts a mechanical seal form, without the need for air source and power supply. Whether it is a paper barrel or a metal barrel, from a diameter of 300-500mm, no replacement of sealing parts is required, and it can seal different barrel diameters). Especially the double iris valve interface, during the connection process, the inner and outer iris valves open respectively, forming an interlock relationship, until the barrel lid opening process is completely in a containment environment, effectively avoiding powder spillage, and the protection level can reach OEB 4 sealing level.
