FIELD: material grinding equipment. SUBSTANCE: vibratory mill has frame, vertical cone, grinding chamber, outer housing and funnel-shaped member rigidly and axially fixed inside outer housing and oriented substantially in parallel with direction of material flow. Funnel-shaped member is adapted for deflecting material to protect outer housing, which is positioned downstream of material feeding device. Funnel-shaped member is positioned at the level of housing outlet end or projects from it. Frame has vibratory ring mounted at least partially in opposed relation to cone. Outer housing rests upon frame portion adjacent to ring. EFFECT: increased efficiency and simplified construction. 8 cl, 5 dwg
