GXF-159CHThe valve mouth type vacuum powder quantitative packaging machine is fed by a variable speed screw, adopts negative pressure suction technology inside the bag, and has functions such as automatic dust recovery. Mainly designed for the ultrafine powder industry with light density, high packing density, strong flowability, strong air affinity, ultra-fine particle size, high gas content, and inability to be packaged in one go. Strictly control the dust escape from the production site to ensure a clean production environment. This model adopts frequency conversion speed regulation function, electronic automatic measurement technology, controlled by PLC program, which can completely solve the problem of one-time filling of ultrafine powder, with accurate measurement and dust-free characteristics. Widely used in ultrafine powders such as carbon black, nano calcium carbonate, ultrafine talc powder, kaolin, silica, stabilizers, stearic acid, corn starch, bentonite, etc.
