Abstract (en)

This invention provides a process for reducing the average particle size of a granular material by a factor of at least 20 by: - providing a mixing vessel equipped with (A) a high speed disperser and (B) a rotor stator mixer, - providing a liquid medium to the mixing vessel, - switching on the high speed disperser (A) at a speed ranging from 1 to 50 m/s, - adding to the mixing vessel a granular material having an average particle size ranging from 1 to 5 mm, - operating the high speed disperser (A) for a period of time sufficient to reduce the average size of the granular material by a factor of at least about 10, thus producing granules of an intermediate average size ranging from 0.1 to 0.5 mm, and - switching on the rotor stator mixer (B) and operating it for a period of time sufficient to reduce the average size of the intermediate granules by a factor of at least about 2.
