250kg soft and rigid PVC compounding pelletizing line, CPVC
This line adopt SJZ65/132 conic twin screw extruder and it is
mainly used for producing PVC granules. With different screw
design, it can produce rigid PVC granules, soft PVC granules, CPVC
granules etc. The output for rigid PVC is around 250kg/h and for
soft PVC and rigid PVC, the output is around 180kg/h. The process
flow of this line as blow:
PVC powder + additive --- mixing---material feeder---twin screw
extruder--- extrusion die --- pelletizer --- air blower --- silo
--- vibrator --- air blower --- silo
The screw of SJZ65/132 conic twin screw extruder adopt material
38CrMoAlA, Nitriding,surface Chrome plate, nitriding Layer
Thickness:0.5～0.7mm,surface Rigidity:800～900HV. Conic twin screw
will provide powerful safeguard for the PVC plasticization, and the
Siemens PLC control system make more convinient operation. The
degassing system will ensure the quality of final PVC pipes.
The gearbox adopt hardening teeth gearbox, made by Jiangyin gearbox
manufacturer which is top brand in China. The motor adopt 37kw
Siemens standard motor and invter adopt ABB or Siemens. The 3kw
degassing system will ensure the quality of final granules. The
screw core temperature control system will improve the
plasticization of the material.
The 3kw pelletizer is well blanced to match the extrusion die face.
The 3kw air blower will blowing the granules into silo immedately
after granules fall down. According to different formulation, the
vibrator could be designed as cooling vibrator.
