Abstract
Apparatus for dispersing particulate material in a liquid, for example, particulate coal and agglomerating oil in water, comprising an upwardly extending, cylindrical container for the flow of the coal, oil and water upwardly therethrough passed a lower, flat blade type turbine rotor, an intermediate knife blade type turbine rotor and an upper pitched blade type turbine rotor. An annular shaped portion is around the intermediate rotor and houses the intermediate rotor in a cylindrical duct, longitudinally extending baffles extend upwardly along the container inner surface and are spaced therefrom. The lower rotor causes radially outward flow of the coal-water-oil mixture, the intermediate rotor causes fine break down and homogenization of the coal-water-oil mixture, while the pitched blade type turbine rotor causes reverse flow of the homogenized coal-water-oil mixture producing seed agglomerates of carbonaceous coal particles and oil leaving any ash particles dispersed in the water.
