Abstract

1,173,509. Mixing apparatus. H. LIST. 17 Aug., 1967 [22 Aug., 1966], No. 38015/67. Heading. B1C. [Also in Division B5] A plastics working extruder and plasticizer comprises a feed screw 30, temperature controllable perforated plates 5-7 and stirring and kneading elements 31, 32 mounted on a shaft 34 which passes through screw 30, the shaft being rotated and oscillated axially by drive means 55. Plates 5-7 may be provided with induction or resistance heaters or fluid flow passages (9, 10), Fig. 2 (not shown). Generally the plates are heated, but if the mechanical working of the material due to movement of elements 31, 32 and passage through the plate perforations is excessive, they may be cooled. Screw 30 does not move axially and a helical groove 36 prevents movement of plasticized material between screw 30 and shaft 34. In a second embodiment, Fig. 1 (not shown), feed is by means of a ram (20) and in this case a shaft carrying stirring and kneading elements (22, 23) is fixed to ram (20) and the whole assembly rotates and has a relatively slow axial reciprocating movement on which is superimposed an impulsive axial oscillation. In a third embodiment, Fig. 5 (not shown), a feed piston (41) reciprocates axially and is keyed to rotate with a shaft (43) carrying the stirring and kneading elements, but moves axially independently thereof. A seal (45) prevents leakage of plasticized material between piston (41) and shaft (43).
