Abstract: A device for increased micronization efficiency of solid materials. The device including a housing with two discs, separately driven by motors through axles, such that the discs rotate in opposite directions. Each of discs bears at least two or more wreaths of blades such that two adjacent wreaths that belongs to different discs do rotate, relatively one to another, in opposite directions, forming an area where micronization of material takes place. The wreaths of blades of different discs are faced one against another. All blades of wreaths are identical, in the shape of a “T”, and include three wings; two wings are dimensionally identical and set under the right angle, whereas the third wing is set dimensionally larger than the other wings. Centerline of all three wings meet each other in the center of the blade, on a circle that goes through half of the wreath.
