Detailed Description
For the purpose of enhancing the understanding of the present invention, the present invention will be further explained with reference to the accompanying drawings and examples, which are only for the purpose of explaining the present invention and do not limit the scope of the present invention.
In the description of the present invention, it is to be understood that the terms "center", "upper", "lower", "front", "rear", "left", "right", and the like indicate orientations or positional relationships based on those shown in the drawings, and are only for convenience in describing the present invention and simplifying the description, but do not indicate or imply that the combination or element referred to must have a specific orientation, be constructed in a specific orientation, and be operated, and thus, are not to be construed as limiting the present invention. In addition, in the description process of the embodiment of the present invention, the positional relationships of the devices such as "upper", "lower", "front", "rear", "left", "right", and the like in all the drawings are based on fig. 1.
Referring to fig. 1 and 3, a lining plate for a ball mill comprises a lining plate body 1,
at least one sliding chute 11 is arranged on one side of the lining plate body 1, which is in contact with the materials, and the other side of the lining plate body is fixedly connected with the interior of the ball mill cylinder in an attaching manner;
and each sliding groove 11 is internally provided with a wear-resistant part 2 in a nested manner, the specific implementation process is shown in fig. 2, the wear-resistant parts are of strip-shaped structures, and the wear-resistant parts are directly inserted into the sliding grooves 11 in a nested manner for use, so that the disassembly is convenient.
The arc-shaped wear-resistant part 2 is separated from the lining plate body before the lining plate body 1 is installed on the ball mill, and can be transported independently. After the lining plate body is installed, the overall wear-resisting performance of the lining plate body can be ensured. And when the lining plate needs to be maintained, the arc-shaped wear-resistant part can be easily detached, and the arc-shaped wear-resistant part can be directly replaced.
