FIELD: mechanical engineering. SUBSTANCE: disintegrator for grinding solid materials, such as ore, has housing with charging and discharge branch pipes, rotors mounted in housing for rotation in opposite directions and provided with disk parts carrying beats. Disk part surfaces faced one to the other are provided with annular concentric grooves where free ends of beats of opposite rotor are inserted. Beats are equipped with replaceable cylindrical working members arranged on rods. One end of rods has threaded portion for attachment to disk part of rotor and other end is provided with flange for retaining working members against axial motion. End surfaces of working members are provided with depressions into which rod flanges are inserted. Rotors are composed of detachable disk parts and hubs for joining to electric engine shafts. EFFECT: simplified construction and increased efficiency by quick dismantling and replacement of working members. 10 cl, 1 dwg
