Abstract:
A method for treating cement slurries to reduce the particle size of insoluble material therein, thereby producing microcement, comprising the steps of:delivering a first cement slurry stream to a first vortex nozzle;rotating the first cement slurry stream utilizing the first vortex nozzle to produce a first rotated cement slurry stream;delivering the first rotated cement slurry stream into a chamber;delivering a second cement slurry stream to a second vortex nozzle positioned in opposed relationship to the first vortex nozzle;rotating the second cement slurry stream utilizing the first vortex nozzle to produce a second rotated cement slurry stream; anddelivering the second rotated cement slurry stream into the chamber to collide the second rotated cement slurry stream with the first rotated cement slurry stream to reduce the particle size of insoluble material therein, thereby producing microcement.
