FIELD: treatment of hard, liquid and/or gaseous materials. SUBSTANCE: device has two counter-rotation rotors, rings of which carry rows of blades. Peripheral velocity of extreme blade row is 70-160 m/s. To improve efficiency of hardened mass production, formation of multiphase stable media and gas treatment, particles of material are subjected to action of blades, with width of rings, on which they are positioned, decreasing outwards by 2-10 per cent. EFFECT: enhanced efficiency. 16 cl, 4 dwg |
