extrusion screen changer type applation
Extrusion screen changer is a include one or more of the mesh of the manual or automatic switching device, used for foreign particles during the plasticizing material flows through the filter and filter out impurities. Filter consists of a perforated plate bearing alloy, porous plate installed on the plate or column type of carrier, the carrier may be moving to work in a system location and off-line switching between non-work position. The switch can be installed in any new or existing extruder, melt pump, reactor or other extrusion line. It can be used to filter any type of polymer, rubber or ceramic melt.

It is used in plastics, rubber, chemical fiber and ceramic materials extrusion line. These extrusion screen changers - ranging from low - cost manual screen change to highly complex automatic stabilizer, are suitable for extruders with diameters of 35mm to 300mm in diameter. It is often used in the following production line: 1. From the plastic resin synthesis reaction device to the extruded granulating production line of bulk granules. 2. Ceramic extrusion line. 3. The polymer (plastic and rubber molding production line, including blown film, stretch film, sheet, pipe, profiles, plastic recycling and granulating, drawing, underwater pelletizing, masterbatch granulation, and combined with the production line. 4. Suitable for various granulator, extruder, film machine, drawing machine, sheet extruder, tube extruder. The application of different types of web switch to meet different application and process requirements. Manual type or low-speed net changer request production line must have a short stop filtering time, in order to make the change, and high speed net changer and some special structures in the network can realize don't stop or slow down to replace the network extrusion speed in the net. The low cost of the net switch may produce the secondary waste when changing the net, and the non-shutdown switch can guarantee the minimum of the defective products, but the initial investment is also larger.
