END LINING FOR DRUM MILL DISCHARGE COVER Russian patent published in 2001 - IPC

FIELD: mechanical engineering. SUBSTANCE: end lining is formed of L-shaped plates, with longer side being formed as sector. Wider part of L-shaped plate has curved strip with wedge-shaped depressions. Strip radius is comparable to inner radius of cylindrical part of drum mill discharge cover. Strip is positioned at an angle of 105 deg to sector surface. Plate width is multiple inner perimeter of cover. Plates are fabricated of flexible material of symmetrical or asymmetrical wavy shape with wedge-shaped ridge. Plates may be fabricated from rubber or other resilient flexible wear-resistant material, such as polyurethane, caprolon. EFFECT: wider operational capabilities of lining, increased efficiency and service life. 2 cl, 4 dwg
