Structural features of double screw extruder:
A1: The feeding system of the SJZ series conical screw extruder adopts a large speed ratio forced feeding and is equipped with a hopper vibration device to prevent raw materials from bridging.
A2: The screw core of the SJZ series double screw extruder is heated by an oil heating system; the barrel is cooled by a special air cooling system with low noise and high air supply; the heating system adopts a special PAD temperature control system for Omron extrusion.
According to the user’s high filling formula requirements, it is equipped with a high-speed and high-efficiency alloy screw to achieve the plasticized state and fluid quality.
A3: The special high-torque gearbox, distribution box and imported bearing parts of SJZ series conical twin-screw extruder ensure longer service life.
A4: The electric drive part of the SJZ series double screw extruder is ABB frequency conversion, Siemens electronics, Omron temperature control, Schneider electric control, to ensure the stability of the electrical system, low failure rate and extremely high electrical safety.
SJZ series conical twin-screw extruder is suitable for the following production lines: PE wood plastic profile production line, PVC hot-cut granulation production line, PVC pipe production line, PVC wall panel production line, plastic steel window frame profile production line, PVC powder modified granulation Production line.
