Not necessary for thermal refining equipment and saving manpower, the cold feeding degassing extruder adopts air exhaust technique which has obvious effect on degassing with even temperature for rubber extruding, strong plasticizing capacity and compact products, which helps to improve the quality of rubber products. Moreover, it has compact structure, small coverage, convenient operation and low power consumption. with high efficiency of material feeding at feeding segment, it is featured by good plasticizing uniformity at specially designed plasticizing segment, convenient temperature adjustment, good effect on temperature control, and fine stability of rubber temperature. It is well adapted to various shapes and rubber materials. It has the advantages of small volume, large load capacity, long service life, low noise and stable transmission.
