PARALLEL TWIN-SCREW EXTRUDER SEGMENTS


The intermeshing co-rotating twin-screw extruder is equipped with an exhaust zone to remove moisture, entrained air and volatile components in the material. Sealing elements should be installed on the screw upstream of the exhaust port to seal the melt to build up high pressure; in the exhaust area, that is, the section of the screw opposite to the exhaust port, the filling degree of the material in the screw groove should be relatively low. Low, and communicated with the atmosphere or vacuum pump.



Sealing the melt and establishing high pressure can use reverse threaded elements, reverse kneading blocks or pressure regulating valves. In the exhaust area, a large-lead threaded element (Figure 5) should be used to form a low fullness and a thin melt layer, so that the material has a large free surface that can be exposed and a long residence time to facilitate exhaust.
