ABSTRACT:
A continuous mixer has an elongated trough with two mixer assemblies mounted therein in a mutually parallel, laterally spaced apart relationship for axial rotation in opposite directions. Each mixer assembly has a rigid shaft with a plurality of blades mounted thereon which are shaped and mutually arranged to achieve an intersecting helical effect in the trough. The blades are arranged in sets of at least two, axially adjacent ones of said blades, wherein the blades within each set has a substantially identical circumferential position on its shaft, and the sets are positioned in a circumferentially staggered pattern about the shaft to axially balance the mixing assemblies, and thereby alleviate vibration, even during high speed mixing. Counterbalance weights or eccentric blades on the shafts can also be used to improve the dynamic balance of the mixing assemblies.
