  • PROCESSING SYSTEM AND METHOD FOR PROCESSING A POLYMER-FILLER COMPOSITION, ESPECIALLY A POLYVINYLCHLORIDE-FILLER COMPOSITION
    Publication number: 20240116216
    Abstract: A processing system serves to process a polymer-filler composition, especially a polyvinylchloride-filler composition, and comprises a multi-shaft screw machine, a first feed device and a second feed device. By means of the first feed device, a polymer and a first proportion of a mineral filler are fed into the multi-shaft screw machine. Subsequently, by means of the second feed device, a second proportion of the mineral filler is fed into the multi-shaft screw machine. The gradual mixing-in of the mineral filler achieves a high proportion of the mineral filler in der polymer-filler composition.
