STJ Series Two-Stage Compounding Extruder

STJ系列双阶（组合式）混炼挤出机

Description:
STJ series two-stage compounding extruder consists of two processing stages. The first stage is a SHJ twin-screw compounding extruder without die head. Through the combination of barrel and screw, two stage extruder can exert its strong ability to make the thermo sensibility material (like PVC) melting, compounding, disturbing and decentralizing. The second stage is SD single screw extruder for heat-sensitive material pelletizing. Due to its lower rotating speed, two-stage compounding extruder excels in high-effective pelletizing, compounding and dispersion. The twin screw extruder is advanced in high-pressure extrusion with lower speed and lower temperature. This kind of two stage extruder possesses advantages of simple production technological process, high output, stable quality and low cost.

Applications:
STJ series two-stage compounding extruders are special devices equipped with different kinds of molds and auxiliary machines. This two stage extruder is widely applied to various thermo-sensitive materials, dehydration and volatilization work, such as PVC (Polyvinyl Chloride), XLPE (Cross Linked Polyethylene), halogen-free cable, shield material, high concentration carbon black master batch, rubber dehydrating, and so on.
