Apparatus for the rapid production of concrete having a grout slurry forming device, a cyclonic mixer for aggregate and a weighing device for feeding weighed amounts of aggregate to the cyclonic mixer. The slurry forming device including, subjecting fine particles in a liquid to the action of one or more rotating disc shaped blades, arranged to create within the slurry alternating areas of high and low pressures, thereby breaking up agglomerations. The cyclonic mixer includes, a hopper in which at least two conveyors simultaneously transport aggregate streams tangentially into, in opposite directions inducing helical mixing paths. The weighing device including, an aggregate weigher wherein a number of aggregate storage bins selectively releases aggregate onto a variable speed controlled conveyor. Intimately mixed concrete being formed from the simultaneous release of the grout slurry into the cyclonic mixer combining with the mixing aggregate.
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.
An apparatus for forming a slurry of particles of fine material in a liquid, the apparatus including a housing adapted to receive and hold a slurry of particles of fine materials in a liquid which slurry contains agglomerations of the particles, and located within the housing one or more rotatable 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 pressure such that bubbles are formed in the low pressure zones and are 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.
