Title:
METHOD AND DEVICE FOR THE DISINTEGRATION OF ESPECIALLY INORGANIC MATERIALS
Document Type and Number:
WIPO Patent Application WO2004037425
Kind Code:
B1
Abstract:
The invention relates to a method for the disintegration and tribochemical activation of especially inorganic materials having a crystalline structure, wherein the starting materials are comminuted (disintegrated) to a particle size of less than 1 mu m by the effect of impacting pressure fronts at a pulse duration of less that 10 ñs and a sequence frequency of more than 8 kHz. A conglomerate of activated mixed crystals is then obtained. Said conglomerate has an increased aptitude for the formation of modified crystals when water is added. The duration of the effect of the impacting pressure fronts continues until the crystal lattice structure of the particles (30) is destroyed. A device for the disintegration and tribochemical activation of said materials is based on rotating disks whereon moulded bodies with aerodynamical profiles are arranged, said moulded bodies being continuously displaced in a transonic speed range and impacting pressure fronts being produced on the outflow surfaces thereof.
