ABSTRACT:
A mixing apparatus is disclosed comprising a vessel, a central shaft adapted to be rotationally driven and a stirrer arranged for stirring operation upon rotation of the shaft. The stirrer includes upwardly and downwardly extending interleaved blade assemblies arranged for relative rotation and a cross blade transversely extending from the shaft in a sawtooth pattern at the lower level of the blade assemblies. The downwardly extending blade assembly is stationary, and it is carried by an upper support member fixed to the vessel. The upwardly extending blade assembly is carried by a lower support arm fixed to the shaft for rotation therewith. The cross blade extends along the lower support arm, and it comprises a plurality of elements each connecting and extending between a pair of adjacent upwardly extending blades or the shaft and an upwardly extending adjacent blade.
