ABSTRACT:
A constant level slurry tank system suitable for use in coating investment casting wax patterns with a ceramic shell by repeated dipping in the slurry. The system comprises a rotating drum, a slurry reservoir and a fixed trough surrounding the drum. The drum has four openings at the desired slurry level, which open into the trough, and two paddles 19 which sweep the trough. A pump constantly pumps slurry from the reservoir into the drum. When the slurry reaches the desired level, excess slurry overflows into the trough via the openings and is swept by the paddles to a trough outlet which leads back to the reservoir.
