Abstract

1380149 Screw mixers BUSS AG 16 May 1972 [17 May 1971] 22816/72 Heading B1C In a screw mixer in which the screw rotates and simultaneously reciprocates in a casing having inwardly projecting teeth, the screw thread is interrupted at least four times in each full turn. Correspondingly these will be at least four cooperating rows of teeth 10. The casing may be in two parts separable and symmetrical about a plane passing through the axis. The individual sections 6 of the screw will take the shape of a rhombus the two sharp corners 15 of which are chamfered; the motion of the screw is such that only a small dead space 16 is left round each tooth. In a modification, Fig. 3 (not shown), the teeth are of circular crosssection and the dead space is further reduced.
