Conical Twin Screw Extruder has compact design that saves variable production area and the angled alignment of the screw axes makes space for a rugged distribution gearbox and a substantial back pressure bearing. The Extruder has relatively small screw diameter that results in minimal back pressure forces in the metering zone, which contributes to the long service life of the back pressure bearing and the screw designed for PVC processing ensures gentle plasticizing. The Extruder is operator friendly and has a conical twin screw gear box. The Conical Twin Screw Extruder has bimetallic screw and barrel and minimizes the energy input.
