  • APPARATUS FOR PROCESSING SCRAP CROSS-LINKED THERMOSET ELASTOMERIC MATERIAL
    Publication number: 20130136820
    Abstract: An apparatus for processing thermoset cross-linked elastomeric scrap material has a batch-operated high shear mixer for inducing chemical reactions to partly devulcanize the material in a first devulcanizing stage. A continuously-operated multi-screw cooled extruder receives the partly devulcanized material from the high shear mixer and further devulcanizes the material by a mechanical shearing action in a second stage to produce an extruded product for revulcanization.
