AI Technical Summary
The wear-resistant lining of the existing drum ball mill needs to be improved in terms of crushing efficiency, especially in cross-section parallel to the drum axis, when the steel ball falls on the backing plate, the material below can only be smashed, and the crushing capacity is limited.
A wear-resistant lining plate including a plate body, a crest and a mortar groove is designed. The peak extension direction is parallel to the drum axis, and the mortar groove extension direction is perpendicular to the drum axis. The width of the mortar groove gradually decreases from the opening to the bottom, increasing the contact point between the steel ball and the lining plate, thereby improving the crushing efficiency.
By setting up multiple mortar grooves, the steel ball can have two contact points with the mortar groove when it falls, which significantly improves the crushing efficiency and allows the material to be smashed more effectively.

Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of ball mills, in particular to a wear-resistant lining plate for a drum-type ball mill. Background Art
[0002] A ball mill is a key device for crushing materials and then pulverizing them. It is widely used in the production industries such as cement, silicate products, new building materials, refractory materials, chemical fertilizers, non-ferrous metal beneficiation, and glass ceramics. A wear-resistant lining plate is provided on the inner wall of the drum of a drum-type ball mill to protect the drum. The wear-resistant lining plate of the prior art is wavy in the cross-section perpendicular to the axis of the drum, so that it is easier to lift the steel balls inside when the drum rotates, enabling the steel balls to rise to a higher height and then fall, thereby improving the pulverizing effect. However, its inner side is relatively flat in the cross-section parallel to the axis of the drum, and when the steel balls fall on the lining plate, they can only crush the materials below it, so its pulverizing ability needs to be improved. Content of the Utility Model
[0003] The technical problem to be solved by the utility model is to provide a wear-resistant lining plate for a drum-type ball mill aiming at the above-mentioned technical deficiencies.
[0004] To solve the above technical problem, the technical solution adopted by the utility model is: a wear-resistant lining plate for a drum-type ball mill, including a plate body. There are no less than two bolt holes provided on the plate body. A wave crest is provided on one side of the inner side of the plate body, and the extending direction of the wave crest is parallel to the axis of the ball mill drum. A plurality of mortar grooves are also provided on the inner side of the plate body, and the extending direction of the mortar grooves is perpendicular to the axis of the ball mill drum. The width of the mortar groove gradually decreases from the opening to the bottom.
[0005] Preferably, the cross-section of the mortar groove is arc-shaped.
[0006] Preferably, a groove is provided on the outer side of the plate body.
[0007] Preferably, the slope of the side of the wave crest facing the rotation direction is greater than the slope of the side facing away from the rotation direction.
[0008] The beneficial effect of the utility model is: a plurality of mortar grooves are provided on the inner side of the plate body. The width of the mortar groove gradually decreases from the opening to the bottom, and the extending direction of the mortar groove is perpendicular to the axis of the ball mill drum. When the steel balls fall into the mortar grooves, there can be two contact points between them and the mortar grooves, thereby improving the pulverizing efficiency. Description of the Drawings
[0009] To more clearly illustrate the technical solutions in the embodiments of the present utility model, the following will briefly introduce the drawings required for the description of the embodiments. Obviously, the drawings in the following description are only some embodiments of the present utility model. For those of ordinary skill in the art, without creative efforts, other drawings can also be obtained based on these drawings.

[0013] The following will clearly and completely describe the technical solutions of the present utility model in combination with specific embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, rather than all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present utility model.
[0014] Specific embodiments: As shown in Figure 1-2 A wear-resistant lining plate for a drum ball mill includes a plate body 1. There are no less than two bolt holes 3 provided on the plate body 1. Bolts can pass through the bolt holes 3 to fix the plate body 1 on the inner wall of the ball mill drum. On one side of the inner surface of the plate body 1, there is a wave crest 2 protruding from the inner surface of the plate body 1. The extending direction of the wave crest 2 is parallel to the axis of the ball mill drum. The wave crest 2 enables the steel balls to rise higher and then fall. On the inner surface of the plate body 1, there are also a plurality of mortar grooves 4. The extending direction of the mortar grooves 4 is perpendicular to the axis of the ball mill drum. The width of the mortar grooves 4 gradually decreases from the opening to the bottom. When the lining plate is at the bottom of the drum, the opening of the mortar groove 4 faces upward, and the material can enter the mortar groove 4. When the steel balls falling from above land in the mortar groove 4 and are very close to the side wall of the mortar groove 4, the material near the side wall and the bottom of the mortar groove 4 can be crushed by the steel balls, thereby improving the crushing efficiency. When the lining plate is at the top of the drum, the material in the mortar groove 4 will fall under the action of gravity.
[0015] In this embodiment, the cross-section of the mortar groove 4 is arc-shaped, and the radius of the arc is slightly larger than the radius of the largest steel ball in the drum.
[0016] In this embodiment, the outer surface of the plate body 1 is provided with a groove 5, which can reduce the weight of the plate body 1.
[0017] In this embodiment, the slope of one side of the wave crest 2 facing the rotation direction is greater than that of the side facing away from the rotation direction, that is, the side of the wave crest 2 facing the rotation direction is steeper, so that it is easier to lift the steel balls upward when the drum rotates.
[0018] In this article, specific embodiments are used to elaborate on the principles and implementation manners of the present invention. The description of the above embodiments is only used to help understand the method and its core idea of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and modifications can be made to the present invention, and these improvements and modifications also fall within the protection scope of the claims of the present invention.
