Corrugated lining plate

Abstract

The invention discloses a corrugated lining plate. The corrugated lining plate is mounted on the inner surface of a ball mill barrel, and comprises a body, wherein the upper end of the body comprises a concave arc surface, the lower end of the body comprises a convex arc surface matched with the inner surface of the ball mill barrel, the concave arc surface and the convex arc surface have the same center line, the front and rear ends of the body respectively comprise an extension face respectively extending towards the center line, the front and rear ends of the concave arc surface and the convex arc surface are respectively connected through the extension faces, the left and right ends of the body respectively comprise a plumb face, left and right ends of the concave arc surface and the convex arc surface are respectively connected through the plumb faces, the concave arc surface is provided with four grooves parallel to the center line, the cross sections of the grooves are arc-shaped, neighboring grooves are in arc linkage, two ends of each groove are respectively in arc linkage with the plumb faces, the convex arc surface is provided with a rectangular pit, the rectangular pit internally comprises a lug boss, a rectangular flat table is arranged on the part of the concave arc surface, corresponding to the lug boss, the center of the lug boss is provided with a stepped through hole passing through the lug boss and the rectangular flat table.

Description

technical field [0001] The invention relates to a corrugated liner. Background technique [0002] Ball mills are suitable for grinding various ores and other materials, and are widely used in mineral processing, building materials and chemical industries. There are materials and grinding bodies in the cylinder of the ball mill, and a liner is fixed on the cylinder wall. When the cylinder rotates, the grinding body relies on the lifting of the liner to crush or grind the material. The ordinary flat liner has a poor lifting effect on the grinding body. , so the crushing efficiency of the material is not high. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a corrugated liner to overcome the deficiencies in the prior art. [0004] The technical solution adopted by the present invention to solve the technical problem is: a corrugated liner installed on the inner surface of the ball mill barrel, including a body, th...
