SJS series two-stage machine characteristics Structure Both Stages are SJ low speed single screw extruder. Two machines are placed vertically. Principle and applications: Increasing the operation variables and realizing the process because of two-stage machine. Special for Recycling waste film granules line.
Usually the first compounding extruder runs at a high speed for good mixing and high output capacity. The second extruder must be a larger diameter single screw one that can run at lower screw speed. The lower screw speed can avoid over-heating by internal coolin system and strong heat exchange ability.The functional separation allows opearation allows opeartor to more flexibly control the expectable material mixing process and temperature.
