<p>A mixing machine for dispersing finely divided solid particles in a liquid vehicle including a pair of co-axially extending shafts with an impeller disposed on the end of each shaft, said shafts being separately driven by a pair of variable speed drive motors, one of the impellers being a relatively smaller high speed impeller and the other of said impellers being a relatively larger low speed impeller. The high speed impeller is disposed adjacent to and in co-axial relationship with the low speed impeller with the radial spacing between the periphery of the high speed impeller and internal wall portions formed on the low speed impeller being extremely small whereby a shearing action is imparted to agglomerates being processed in the mixture as they pass through the space between the periphery of the high speed impeller and the wall portions on the low speed impeller.</p> |
