MIXER APPARATUS Abstract of the Disclosure A new and improved mixer apparatus is especially adapted for use in a program controlled system for making foundry molds and includes a mixing device for dispensing a mixture of molding sand and binder onto a mold forming pattern in a flask. The device includes a mixing chamber having an inlet for receiving sand adjacent an upper level and a discharge outlet for dispensing a mixture adjacent a lower level. A rotor is mounted on a central axis of the chamber and includes an elongated shaft extending between the inlet and outlet. A flow metering unit divides the chamber into upper and lower sections and is operable for controlling the flow rate of material toward the discharge outlet. The rotor includes upper and lower sets of blades pivotally mounted on axes parallel and spaced radially out- wardly of the central axis of the chamber. These blades in- clude free outer edges extending along and in close proxim- ity with adjacent inside wall surfaces of the upper and lower chamber sections and these blades interact with the chamber wall surfaces forcefully moving and mixing the sand/binder mixture around the surface of the chamber wall outwardly against the same with a spatula-type mixing action. The binder system for the molding sand includes at least two - i - components which are introduced into the respective upper and lower chamber sections in order to provide thorough intermixing and pre-mixing of the materials so that high quality molding sand is ready to be dispensed onto a mold forming pattern as it leaves the outlet of the mixing chamber. - ii -
