PE WPC granule production line
PE WPC granule production line consists of co-rotating twin screw extruders, granulation die head, plastic grain cutting machine, stainless steel air
cooling device. And discharging board of die head adopts 28GrMOALA high quality
alloy steel with nitemper. PE WPC granule production line die body, adopting 45# forging for processed and
logical runner outlet, ensure symmetrical extrusion for pellet. With infinite variable
speed drive motor, accurate resilience cutter, the plastic grain cutting machine can
ensure the cut noodle smooth, prolonging the useful life of discharging board
according to different granulation speed. Cyclone separation with several strong
force fan improves the cooling and give a guarantee for positive quality pellet.
Features of the co-rotating twin screw extruder
The extruder is adopted an accumulative structure in assembling elements, by
changing difference parts for different materials processing technology to meet
uses’ requirement. To achieve machine’s multi_purpose. Extruder gear box
designing is and structure is compact which feature high torque output and stable
running. The extruder barrel is double_layer making form wear-proof alloy steel a301, hardness HRC60-64. The extruder screw is made form high-speed tool steel W6Mo5Cr4Vo2, vacuum hardening reach HRC58-62, having strong wearability and long life use. Extruder temperature adopts digital
control system to realize temperature accurate control automatically. Head of
extruder equipped with pressure sensors and melt temperature measurement
thermocouple to inspect and control extrusion conditions, and to meet the technical
requirement for various materials processing.
