1,107,637. Mixing apparatus. BUSS A.G. 20 Jan., 1966 [8 Feb., 1965], No. 2594/66. Heading B1C. A worm for mixing and kneading plastic masses has interrupted vanes 9, 10, 9', 10' - - - on a shaft 2 rotated and moved linearly axially in a housing 4. such that during each rotation the shaft completes a forward and rearward movement relative to the or each baffle ring 6. The creach ring is shaped to provide a constant gap between the ring and an adjacent vane throughout the axial and rotary movement. The mass in passing from inlet 3 to outlet 8 is squeezed past the ring or rings as a thin film to facilitate degasification, the released gases passing through outlet or outlets 7. The housing has removable teeth 5, 5a intermeshing with some of the vanes. |
