Abstract

The utility model discloses a barrel lining plate of semi -autogenous mill, it includes lining plate body, connecting rod, mounting hole, and lining plate body has four faces, and connecting rod is located in lining plate one side wall, and mounting hole is located in lining plate three side walls and is adapted with connecting rod, and the second inclined plane of lining plate two faces and four faces is equipped respectively first, and the second, and two are pasted. Lining plate body is several groups, and the front and back two groups are fixed through the insertion of connecting rod and mounting hole, and the left and right two groups are spliced through the first and second inclined plane, and the surface of lining plate body has first positioning hole, and the inner wall of barrel has corresponding second positioning hole, and two are fixedly connected through bolt. The application lining plate is through the insertion of connecting rod and mounting hole, realizes the simple and stable fixation of front and back lining plate, can effectively resist the front and back direction impact force that material and grinding medium bring when semi -autogenous mill operates, prevents the relative displacement of front and back lining plate, guarantees the stable structure of lining plate whole, thereby better bear working load.
