This production line is widely used for all kinds of heating sensitive materials and large-volume degassing process, e.g.
PVC, XLPE, non-resistance cable compound, shielding compound, high-density carbon master batch and procedures after rubber dewatering.
Structure：
Stage 1 is high-speed co-rotating twin-screw extruder； stage 2 is low-speed single-screw extruder. Two machines are placed vertically.
Principle and characteristic：
Take advantage of twin-screw extruder and single-screw extruder.
Twin-screw extruder transports forcedly, plasticize and compound expeditiously, shear, disperse and have no die-head return-pressure；
Avoid over-heat, which caused by high shear. Single-screw extrudes at a high pressure, but shear at a low speed, so obviate over-heat conflict.
Combination of twin-screw extruder and single-screw extruder, make process function decompose, increase separate operational variable,
in favor of every process’s multiple step optimize, and get higher effect and capacity；
It has wide application in every kind of heat sensitive material and large-volume dehydration etc,
such as： the treatment of PVC, XLPE, zero halogen cable material, shield material, high and thick carbon material, and rubber after dehydration and etc.
