FIELD: powder engineering. SUBSTANCE: this method and device serve for treating hard alloys wastes. Wastes are placed in a shell hollow formed by two hemispheres of explosive. Charge in a caprone net is mounted within chamber. Explosion of shell material is initiated with the help of electric detonator. Convergent impact wave arising in result of explosion charges hard alloys waste material in layers inspiring its movement and distraction. EFFECT: enhanced efficiency. 3 cl, 1 dwg
