ABSTRACT:
A high intensity conditioning mill for conditioning aqueous pulp containing particles of clay and mineral impurities preparatory to subjecting the pulp to froth flotation comprising a conditioning vessel for containing the body of aqueous pulp, a plurality of generally horizontal baffles mounted within said vessel and dividing the interior thereof into a plurality of chambers, each baffle being formed with a central, circular hole, inlet means for feeding aqueous pulp to the lowermost chamber, outlet means for removing conditioned aqueous pulp from the space above the uppermost baffle, a rotatable, generally vertical drive shaft centrally positioned to rotate in said vessel and extending generally concentrically through each hole in each baffle and a plurality of impellers mounted on said shaft and generally positioned within a hole of the horizontal baffle, the impellers being of a size relative to said holes sufficient to provide passageways for the aqueous pulp from each chamber to each adjacent chamber whereby the aqueous pulp is caused to flow from the lowermost chamber to the space above the uppermost baffle while being subjected to the action of the impellers.
