Abstract:
A method of forming a slurry of particles of fine materials in a liquid, wherein the mixing and dividing of agglomerations of the particles of fine materials is carried out by subjecting a slurry of the agglomerations of particles to the action of one or more rotating discs, said one or more discs including four substantially equal quadrants wherein each quadrant includes a rectangular zone lying in the plane of rotation of the one or more discs, a first triangular-shaped blade continuous with the rectangular zone but lying at an angle to and above that plane and a second triangular-shaped blade continuous on an opposing side of the rectangular zone but lying at an angle to and below said plane, the rectangular zones extending along the diameter of the one or more discs the one or more discs being arranged to create within the slurry alternating areas of high and low pressures, bubbles being formed in the low pressure zones and being compressed in the high pressure zones to implode with great force thereby breaking up the agglomerations of particles and at the same time separating and dispersing the individual particles of fine materials.
