1. waste old breaks a sulfur regeneration novel method, it is characterized in that, comprises the steps:

  • A, waste old is obtained rubber grain through broken process fragmentation;

    B, rubber grain is transported in type rubber regenerating machine through constant feeder, electromagnetism zone heating in type rubber regenerating machine, the heating of segmentation insulation, the high-speed stirring mode of insulation is adopted to carry out disconnected sulfur regeneration, condition control at 200 DEG C and with no pressure under, time is 5-7 min, is then delivered to by material in Banbury mixer to carry out secondary plasticizing and complete disconnected sulphur process;

    C, molding procedure of plasticating;

    the material after disconnected sulphur is first through two refiner refinings, machine filter glue is filtered again through one, extrude through forcing machine the film obtained again after filter glue, obtain film is broken into desired thickness block reclaimed rubber through automatic cutting, then through endless belt conveyor conveying packaging warehouse-in after an EVA film laminating.
