Abstract
A mixing apparatus for continuously preparing pulverous to granular thermoplastic synthetic material. The mixing apparatus includes a tubular, rotatably mounted horizontal container, on the inner surface of which mixing instruments or tools are attached. An inlet and outlet for the material to be mixed are respectively located near the ends of the container. A shaft is rotatably arranged about the axis of the container and extends at least over the entire length of the container. Mixing instruments are likewise attached to the shaft. The mixing instruments, in the region between the inlet and outlet, comprise a plurality of sections of single or multi-threaded worms which extend in the radial direction from the shaft to the inner surface of the container. These sections are adjacent to and spaced from one another, and are alternately mounted to the shaft and to the inner surface of the container. The shaft is longitudinally displaceable with regard to the container, and the container and shaft may be rotated in opposite directions to one another.
