Melt extrusion screen changer

The screen changer is a manual or automatic switching screen changer consisting of one or more filters, which is used to filter out foreign particles and impurities when plasticizing material flow filters. The filter is supported by an alloy porous plate, which is mounted on a plate or column carrier. The carrier can be moved to switch between the working position of a system and the off-line non-working position. The net changer can be installed on any new or existing extruder, melt pump, reactor or or other extrusion production line. It can be used to filter any type of polymer, rubber or ceramic melt.
