Two-stage ( twin screw/ single screw) Compounding Extruder Set Structure First stage is TE high speed co-rotating twin screw extruder. Second stage is SE low speed single screw extruder. First stage extruder and second stage extruder are placed vertically. Principle: Take advantage of twin screw extruder and single screw extruder. Twin screw extruder force transportation, powerful compounding and good dispersion, make the material high effective plastizing. Single screw extruder can effective cooling the material, so this two stage machine structure will have high effective production and higher capacity. Application: For different kinds of thermo-sensitive material, like PVC, XLPE, LSHF flame retardant cable material, shielding material etc.
