Abstract

1,015,088. Continuous - discharge mixers. GEORG FISCHER A.G. April 29, 1964 [May 2, 1963], No. 17889/64. Heading B1C. [Also in Division B3] Apparatus for the continuous preparation of foundry sand comprises a drum 1, whose length is shorter than its diameter, mounted for rotation about an axis inclined at between 5 degrees and 30 degrees to the horizontal and motor-driven at such a rotational speed that a part of the sand 9 is in free fall in the drum, the materials being charged into the drum by a conveyer 10 and prepared sand spilling over a rim 8 on to a further conveyer 11. The speed of the drum is infinitely adjustable by a handwheel 16 connected with a transmission 6 from the driving motor 5, Fig. 1 (not shown). Water and additives such as binding agents and pulverized coal are introduced through a valve-controlled pipe 12. The frusto-conical bottom 2 of the drum is heated by a radiant heater 15 and the drum is clad with heatinsulating material 21. The inclination of the drum is adjustable by a handwheel 14. The angle α formed by a generatrix of the bottom 2 with a plane perpendicular to the drum axis is preferably greater than the angle # between the drum axis and the horizontal. The rate of the water through the pipe 12 may be automatically controlled by apparatus measuring the moisture content of the outgoing sand.
