Device for micronization of solid materials and its use

A device for micronization of solid materials comprising a housing in which are positioned two discs, independently driven by respective motors through respective axles such that said discs rotate in opposite directions;

• on each of said discs are at least two or more wreaths of blades distributed such that two neighboring wreaths, which belong to different discs, rotate, one relative to the other, and in opposite directions, thus forming an area where micronization of material is taking place, and the wreaths of blades of different discs are faced one against another, wherein all blades of the wreaths are identical, having the shape of the letter “T” comprising three wings, where two of the three wings are dimensionally identical and positioned under the right angle, whilst a third of the three wings is dimensionally larger than the two wings, and where centerlines of all three wings intersect in a center of the blade, on a circle that goes through half of the wreath.
