Characteristic of two-stage extruder:   The JSJ series two-stage extruder consisted of two stage components. The first stage is JSJ co-rotating twin-screw extruder, the second stage is JD single screw extruder. This machine first of all to realize material better compounding and shearing by twin-screw, then the single screw fulfills the task of extruding and granulating. The scientific and advanced structure can avoid material decomposition phenomena due to overheating. To combines the advantage of twin-screw and single screw together and complementation, likewise, propitious to every craft distribution and optimize so that making higher efficient and production capacity. The two-stage extruder best suits for producing PVC, POM, XLPE thermo-sensitive material etc.
