Upper single screw for gentle feeding & pre-plasticizing, lower twin screw for compounding & pelletizing. Designed for complex material processing.
Upper single screw pre-plasticizes material gently, then lower twin screws provide intensive compounding for optimal dispersion.
Single-screw upper stage prevents material degradation during feeding — critical for heat-sensitive materials like PET and PLA.
Twin-screw lower stage delivers excellent dispersive mixing for filled compounds, color masterbatch, and reinforced plastics.
Handles PET, PLA, ABS, filled compounds, and blended materials — one machine for multiple recycling challenges.
The single + twin screw granulator consists of 5 main components
Gentle feeding and pre-plasticizing stage. Prevents material bridging and ensures consistent feed to the lower stage.
Co-rotating twin screws for intensive compounding, degassing, and homogenization before pelletizing.
Dual-zone PLC control for independent speed and temperature management of upper and lower extrusion stages.
Water-ring or water bath cooling system with centrifugal drier for uniform pellet solidification.
Precision die face or strand pelletizer with rotary cutter for consistent pellet shape and size.
