Embodiment Construction

[0024] Figure 1a Firstly, a molded body 1 of typical design is shown together with flow lines 9 in the subsonic range. The flow lines 9 first flow around the cross section of the fluid 1 , wherein, depending on the cross section of the molded body 1 , the laminar flow can be interrupted and eddies 3 occur in the rear region of the molded body 1 .

[0025] Figure 1b shows the speed ratio in the so-called supersonic speed range. A region is formed in relation to the surface of the molded body 1 in which the relative velocity of the surrounding air locally reaches supersonic velocity. This region is marked with "Ma > 1" in Fig. 1b. This area is in turn bounded by the shock pressure working face 4 with a short pressure rise and a final pressure drop. Point 5 marks the location of the in particular mechanical load on the upper surface of the molded body 1 .

[0026] FIG. 2 shows the impact pressure of the working surface 4 on the particles 30 . The particles 30 alternately pas...

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 mum by the effect of impacting pressure fronts at a pulse duration of less that 10 mus 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.

Description

technical field [0001] The invention relates to a method and a device for the disintegration and tribochemical activation of, in particular, inorganic materials. Background technique [0002] Disintegration is known to have a variety of uses. For example, in the production of cement in the heavy industry field, the cold stone and various additives are first crushed, then heated to 1400°C to 1600°C for sintering, and finally ground to the required particle size. The disadvantage of this method is that a lot of energy is required to activate the raw material. [0003] DE 195 48 645 discloses a method for achieving an increased potential energy value and thus increased chemical reactivity through tribochemically treated crystals. For example, mechanical activation of cement can greatly increase the strength of hydrated mineral binders. The reason for this is the original particle size and lattice interference of these particles. [0004] Various processing methods are avail...
