MILL Russian patent published in 1994 - IPC

FIELD: fine disintegration and activation processes in powder metallurgy. SUBSTANCE: axles of rotors 4 are disposed inside casing 1 in apices of regular polygons while distances between axes of rotors 4 and those between walls of casing 1 shall not exceed 3 and 1.5 diameters of rotor 4, respectively. Besides, axles of rotors 4 may be disposed in joints of grid formed by regular triangles and squares. As a result, the number of collisions between milling bodies and material particles grows. EFFECT: intensified disintegration and activation processes. 2 cl, 3 dwg
