摘要:
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.
摘要:
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.
摘要:
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.
摘要:
The invention relates to a multi-shaft extruder for the continuous treatment and/or processing of bulk material, especially a powdery, granular or flocculent product, comprising a plurality of shafts (3) which are arranged in a crown-like manner in a cavity (1) of an extruder housing (2), said shafts extending parallel to the axial direction (A) of the extruder and forming an inner processing chamber (1a) inside the crown, and an outer processing chamber (1b) outside the crown. Each shaft carries a number of axially successive processing elements (4), at least part of the same being elements (4a; 4c; 4e) having a transporting effect, and with which adjacent shafts engage in a sealed manner at least in partial regions. At least one transporting endless screw element (4b; 4d; 4f) comprising at least one transporting screw thread (9, 10; 14, 15, 16; 19, 20) is placed in the region of the supply opening (21) in the extruder housing (2), and does not engage in a sealing manner in at least one partial region along the axial direction (A).
