JDL Parallel Co-rotating Twin-screw Plastic Polymer Compounding Extruder_Nine Delong Extrusion
Description:The twin-screw extruder is developed on the basis of the single-screw extruder. Due to its good feeding performance, mixing and plasticizing performance, exhaust performance, and extrusion stability, it has been widely used in extruded products. molding processing. Nine Delong Machinery Co.,Ltd has a range of JS series twin screw extruder.
Twin screw extruder reducer/gearbox:
