Abstract
Description
Technical Field
[0001] This utility model belongs to the field of ball mill technology, specifically relating to a ball mill liner assembly that is easy to replace. Background Technology
[0002] Ball mills are key pieces of equipment used for further pulverizing materials after they have been crushed. This type of grinding mill uses a certain number of steel balls as grinding media inside its cylinder.
[0003] It is widely used in the production industries of cement, silicate products, new building materials, refractory materials, fertilizers, ferrous and non-ferrous metal beneficiation, and glass ceramics, for dry or wet grinding of various ores and other grindable materials. Ball mills are suitable for grinding various ores and other materials and are widely used in mineral processing, building materials, and chemical industries. They can be divided into dry and wet grinding methods. Depending on the discharge method, they can be divided into grate type and overflow type.
[0004] Ball mill liners are used to protect the mill body from direct impact and friction between the grinding media and materials. Different types of liners can also be used to adjust the movement of the grinding media to enhance the crushing effect of the grinding media on the materials, thereby improving the mill's grinding efficiency, increasing output, and reducing metal consumption.
[0005] The liners of the ball mill are directly installed inside the ball mill with bolts. The liners are in contact with the material for a long time, which will damage them. When the liners need to be replaced, the multiple bolts used for installation make it cumbersome to replace them by removing the bolts one by one. Utility Model Content

[0016] Beneficial effects
[0017] The technical solution provided by this utility model has the following advantages compared with the prior art:
[0018] This utility model uses a pressure strip to make the bottom of the pressure strip fit against the top of the liner body. When the liner needs to be replaced, only the fixing bolt inside the pressure strip on one side needs to be removed to replace the damaged single liner body inside the ball mill housing. There is no need to remove all the fixing bolts, which reduces the time required for liner replacement.
[0019] The buffer balls can be installed inside the liner body or removed from the liner body. The number of buffer balls can be increased or decreased according to actual needs, so that the liner body can be contacted by different materials to achieve different functions.

Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.
[0029] Referring now to the accompanying drawings, the various figures are intended only to illustrate certain exemplary embodiments and are not intended to limit the scope of the invention. In the various figures, the same reference numerals denote the same or corresponding parts. The dimensions and scales in the various figures are also for illustrative purposes only and should not be construed as limiting the scope of the invention; these dimensions may be enlarged relative to actual products.
[0030] Reference Figure 1-4 The ball mill liner assembly shown includes a ball mill housing mounting structure 1, and a liner structure 2 is provided inside the ball mill housing mounting structure 1. The number of liner structures 2 is set to multiple, and the multiple liner structures 2 are arranged in a ring array inside the ball mill housing mounting structure 1.
[0031] The ball mill housing mounting structure 1 includes a ball mill housing body 101. An mounting strip 102 is provided on the inner side of the ball mill housing body 101. A pressure strip 105 is provided on the outer wall of the mounting strip 102. The inner side of the pressure strip 105 is in contact with the outer wall of the liner structure 2. The number of mounting strips 102 is set to multiple, and the multiple mounting strips 102 are arranged in a ring array on the inner side of the ball mill housing body 101. The two outer walls of the mounting strips 102 are in contact with the outer wall of the liner structure 2.
[0032] Furthermore, in the above technical solution, an installation groove 103 is provided on one side of the mounting strip 102, and an adhesive strip 104 is provided on one side of the pressure strip 105. The outer wall of the adhesive strip 104 is attached to the inner wall of the mounting groove 103. Bolt holes 106 are provided inside the adhesive strip 104 and the pressure strip 105. A fixing bolt 107 is threaded into the bolt hole 106. The fixing bolt 107 is connected to the mounting groove 103. When the liner body 201 needs to be replaced, it is only necessary to rotate the fixing bolt 107 inside the pressure strip 105 on one side of the liner body 201 to disengage the fixing bolt 107 from the mounting groove 103. Then, the pressure strip 105 and the adhesive strip 104 are removed from the inside of the mounting groove 103. After that, the liner body 201 is removed from between the ball mill housing body 101 and the mounting groove 103 for replacement. The pressure strip 105 on the other side only needs to be removed from the liner body 201 and does not need to be completely removed.
[0033] Furthermore, in the above technical solution, the liner structure 2 includes a liner body 201. The outer wall of the liner body 201 is fitted to the inner side of the ball mill housing body 101. The two sides of the liner body 201 are fitted to the outer walls of the two mounting strips 102. Friction grooves 202 are formed on the inner side of the liner body 201. The friction grooves 202 are spiral-shaped and staggered. A slot 203 is formed inside the liner body 201. An auxiliary strip 204 is formed on the inner wall of the slot 203. A buffer ball 205 is disposed inside the slot 203. After the plate body 201 is installed, buffer balls 205 can be installed on the outer wall of the plate body 201. The buffer balls 205 are used to buffer the material. Alternatively, the buffer balls 205 can be omitted, allowing the material to directly contact the friction grooves 202 on the outer wall of the plate body 201. This allows the plate body 201 to be used in different application scenarios. Furthermore, when the plate body 201 is directly broken, the two ends of the plate body 201 are held together by the pressure strips 105, which will only cause the broken plate body 201 to shake to a certain extent, and will not cause the broken plate body 201 to fall directly into the interior of the ball mill housing 101.
[0034] The above-described embodiments are merely illustrative of certain implementations of this utility model, and their descriptions are relatively specific and detailed. However, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
