Exhaust Rubber Screw Characteristics:

Several rows of pins are fixed on the barrel, around whose inwall the pins are evenly distributed. The corresponding part of the screw has an annular groove into which the pins are inserted. The rubber material carries on lateral, shunt or rotating movement under the action of these pins. The screw' s mixing, kneading and plasticizing capacity are strengthened owing to the pins and the L/D ratio of the screw can be cut down by 2-4. Because rubber material stays in the barrel shorter than before and the pins that are inserted into the material transfers heat, the extrusion temperature of the rubber material drops more than 10"C. So that the rotating speed can be rai sed. Generally, the yield can increase 40%- 70% and the energy consumption drops
25%-40%. The sections of the products have good air tightness. Pin type rubber screws have a wide range of application.
