Abstract
Abstract A method for mixing fluent materials, especially such as components for foundry molding compositions, by establishing at least two circularly moving regions of material, preferably more or less parallel streams advancing with respective vortex-like motions, with transfer of material between the regions or streams; and as basic apparatus therefor, a container driven with an orbital type oscillation, and having internal vertical partitioning to define said regions or vertical paths for the vortex streams, with communication between the defined paths or regions. Apparatus elaborations afford pluralities of containers feeding serially one to another or in parallel discharging to a common acceptor, for batch or continuous operations, permitting simultaneous mixing of all components, either all brought together at once or, as for reactive component mixing, in parallel diverse component group mixing flows, joined for final mixing bringing the reactive components together.
