Abstract

1348333 Mixing apparatus BAKER PERKINS Ltd 14 March 1972 [29 March 1971] 8098/71 Heading B1C [Also in Division B3] Foundry moulds and cores are prepared by delivering two separate mixes prepared in horizontal trough conveyor mixers 1, one of sand and binder, the other of sand and hardener catalyst to a mixing chamber 2, intermixing the two mixes by means of a rotary mixing element (not shown) and allowing the final mixture to drop into a blowing chamber 8, purging the mixing chamber 2 with pressurized gas, allowing the gas pressure in the chambers 2 and 8 to increase sufficiently to enable the final mixture to be blown into a mould or cone box, and opening a valve 9 so that the final mixture is blown into a mould or cone box. After mould or cone blowing the chambers 2 and 8 are moved to a position above a discard pipe 14, and both chambers are purged with pressure gas to force excess final mixture into the discard pipe 14. The mould or cone box is held on a machine table 12 between clamps 13 for the moulding operation.
