ABSTRACT:
Apparatus for mixing powdered and liquid materials to form slurries comprising a mixer body having an inlet for such materials and parallel mixing chambers extending to a discharge outlet. Rotors are mounted for rotation in the chambers and include feed sections leading from the inlet to mixing sections and to the outlet. The mixing section of each rotor includes a first lobed mixing portion having short advancing helices, and reverse helices adapted to quickly wet and pressurize the mixture to force entrapped air back through inlet. The mixing section also has a second mixing portion having an increased number of lobes following the first portion to increase the mixing action and shear on the mixture. The second mixing section is followed by a lobed discharge section adapted to impel the mixture through the outlet.
