Abstract A mixing device for dispensing a mixture of moulding sand and a resin binder system onto a mold forming pattern is disclosed. The mixing chamber has an inlet for receiving sand adjacent an upper level and a dis- charge outlet for the mixture adjacent a lower end. A rotor mounted in the chamber includes an upstanding rotating shaft extending between the inlet and the outlet and a plurality of radially extending mixing elements carried for rotation with the shaft. There are means for injecting binder into the cham- ber between the inlet and outlet for intimate mixing with the sand moved around the shaft by the mixing elements. The injecting means includes a first conduit for injecting a first component of a resin binding system adjacent a first portion of the chamber and a second conduit for injecting a second com- ponent of a resin binder system into a second portion of the chamber inter- mediate the level of the first injecting conduit and the outlet of the chamber. Plates with orifices between said first and second conduits divide said chamber into first and second sections for controlling the flow of intermixed sand and the first component therebetween.
