  • FIG. 1 there is shown in front view the construction of mixing kneader apparatus according to one particular embodiment of this invention. More precisely, it will be understood that a substantially stationary cylindrical housing 2 is supported by means of the braces or support elements 3 upon the base frame 1. The end faces of housing 2 are closed by the flanged covers 4 and 5. At the end of the housing 2 which constitutes the drive side of the equipment there is flanged by means of the cage 6 the transmission 7 and drive motor 8 likewise supported upon the base frame 1. At the opposite end of the housing 2 there is located the bearing cage 9.

  • the construction of the various members which are mounted at both stirrer shafts l3 and 19 may be similar to that disclosed in such application, and therefore, such will only be considered herein to the extent necessary to fully appreciate the underlying concepts of this development, particularly since reference may be had to this application for further details.
  • the product or material is conveyed from the inlet or infeed stud towards the outfeed or outlet stud 11 and thereby is continuously mixed by means of the achieved stirring and kneading effect.
  • the deflecting discs 17 In order to maintain the residence time span of the material at the individual axial sections of the equipment narrower there are provided at the main shaft 13 the deflecting discs 17 and upon the auxiliary shaft 19 the deflecting discs 21.
  • the product arriving from the inlet stud 10 initially is conveyed towards the first deflecting disc 17.
  • This deflecting disc 17 either possesses no or only a very small throughpassage opening for the material in front of the associated kneading bar members 18 so that this material is forced to deviate into the second housing portion50 for the stirrer shaft 19.
  • this material impacts against the deflecting disc 21.
  • Also there the material does not find any or only a small throughpassage 23 so that the material which has dammed up at the deflecting disc 21 again is forced to deviate into the housing 2 of the main stirrer shaft 13.
  • This procedure of alternately deflecting the material from the main housing portion into the auxiliary housing portion and then back again into the main housing portion and so forth repeats a number of times until the product departs from the equipment through the agency of the outlet stud 1 1.
  • FIG. 6 illustrates still a further embodiment of the multiple-spindle mixing kneader of this invention wherein the second shaft 40 equipped with the stirrer blades or elements 41 both rotates and oscillates, this being achieved through the provision of a suitable drive schematically indicated at reference character 100.
  • the extent of the oscillating movement, represented by reference character 42, has been indicated by the phantom line position of the deflecting disc 43 when it assumes its second axial terminal position.
  • the deflecting discs 43 simultaneously serve to clean the lateral surfaces of the disc segments 15, and thus they also tend to maintain themselves clean, in other words provide a self-cleaning effect.
