A system for the preparation of no-bake foundry sands for preparation of metal casting molds. A settable binder is introduced into the sand and thoroughly and uniformly mixed therewith and then discharged around a pattern. The resulting mold then sets up and hardens rapidly without baking. After use to produce a metal casting, the mold is broken up and the sand recycled for further use. The present system is characterized by ease of feed rate variation, coordinated feeding of components, short residence time, efficient mixing and reduced clean-up problems. It comprises a horizontal axis paddle-type rotary mixer, coordinated means for feeding the mixture components to the mixer housing and discharge of the mixture upon demand including at least one gas assisted injection port or nozzle for the binder system and control means for regulating the rates of flow. The apparatus is desirably movably supported to facilitate distribution of the discharge.

A continuous gravity flow apparatus for heating and/or drying of particulate material is vertically disposed and is provided with an inlet at the top and an outlet at the bottom. The apparatus includes a flow passage for the particulate material which is defined between an outer housing and an inner housing. Each of the outer and inner housing defines perforated wall sections allowing for the flow of hot gas through the wall of one housing, into contact with the particulate material, and then out through the wall of the other housing. Manifolds are associated with the outer and inner housings to provide for uniform flow of the gas through the material. The perforated wall sections are positioned and designed to enhance particle-to-particle movement of the material to thereby avoid particle sticking and bridging problems.

Heat exchanging apparatus for handling solids, slurries, gels, filter cakes, powders, and the like, for continuous indirect heating, drying, cooling or reaction of materials passed through the apparatus. The dryer/heater/cooler apparatus is characterized by a stationary horizontal vessel with a rotary heat exchanger including a tubular shaft on which are mounted a plurality of hollow vertical discs through which a heat exchanging fluid is passed. Material to be treated is admitted to one end of the apparatus housing, transported in an axial direction through the annular space between the rotor discs and the vessel toward the discharge end and discharged through an overflow weir after the desired residence time. Several rotor disc designs are shown and described.
