DEVICE FOR MICRONIZATION OF SOLID MATERIALS AND ITS USE

摘要

The present invention relates to the device for micronization of solid materials. The device is consisting of housing (4) with two discs (6a, 6b), separately driven by motors (2a, 2b) through axles (3a, 3b), in such a manner that mentioned discs (6a, 6b) rotate in opposite directions. Each of discs (6a, 6b) bears at least two or more wreaths of blades (8a, 8b) in such a way that two adjacent wreaths that belongs to different discs do rotate, relatively one to another, in opposite directions, thus forming an area where micronization of material is taking place. The wreaths of blades (8a, 8b) of different discs (6a, 6b) are faced one against another. All blades (7) of wreaths (8a, 8b) are identical, of shape of the letter "T", and comprise of three wings (7a, 7b, 7c); wings (7a) and (7b) are dimensionally identical and set under the right angle, whereas the wing (7c) is set dimensionally larger that wings (7a, 7b). Centerline of all three wings meet each other in the center of the blade (10), on the circle that goes through half of the wreath (8a, 8b). In comparison to the prior art, the present invention provides increasing of micronization efficiency by 17-19%.
