  • Elastomer mixtures for rubber manufacture
    Publication number: 20080310251
    Abstract: A device is disclosed for producing elastomer compounds for use in the production of rubbers. The device may include a mixing extruder with at least one mixing area, and at least one charging area for receiving an elastomer; and at least one dewatering area disposed downstream from the at least one charging area for receiving the elastomer.

  • Elastomer mixtures for rubber manufacture
    Patent number: 7407611
    Abstract: A method is disclosed for producing elastomer compounds for use in the production of rubbers. At least one elastomer to be processed for the production of an elastomer mixture can be slowly added to a mixer/extruder and is mixed and plasticized and/or masticated (melted) while it passes through the mixer/extruder. The elastomer, when slowly added to the mixer/extruder, can be present in a fluid medium in an evenly distributed form.

  • Method for continuous mixing and preparation processes by means of special ratios of the lateral surface and the free volume and/or internal and external diameter of the screw
    Publication number: 20050248052
    Abstract: A method is disclosed wherein synthetic materials and elastomers (e.g., PET or rubber) can be carefully processed with throughput amounts which are so high as to improve the quality of the final product and increase the cost-effectiveness 0of the entire process. Process tasks such as mixing, cooling/heating (heat exchange) and de-gassing (exchange of materials) can be carried out simultaneously and with greater efficiency.
