ABSTRACT:
A mixing machine for dispersing finely divided solid particles in a liquid vehicle including a pair of coaxially extending shafts, one shaft being longer than the other, an impeller disposed at the end of the longer shaft, and an impeller assembly connected to the shorter shaft, the impeller disposed on the longer shaft being a high speed impeller and the impeller assembly connected to the shorter shaft being a low speed impeller assembly. The low speed impeller assembly is constructed with a plurality of laterally extending arms attached to the shorter shaft and a plurality of vertically extending rods connected to the outer ends of laterally extending arms. The rods in turn each carry one of the blades or vanes of the low speed impeller. This construction allows the bearing and seal arrangement disposed between the low and high speed shafts to be at a point along the shafts where it will be substantially out of contact with product being processed.
