Description

Technical Field

[0001] The utility model belongs to the technical field of ball mill lining plates, in particular to a composite ball mill lining plate. Background Art

[0002] Ball mill is a key equipment for crushing materials after they are broken. This type of mill is a mill that is equipped with a certain number of steel balls as grinding media in its cylinder. It is widely used in cement and silicate products. The inner wall of the ball mill needs a liner to protect it. The liner of the ball mill can protect the cylinder from direct impact and friction between the grinding body and the material. At the same time, different forms of liners can be used to adjust the movement state of the grinding body to enhance the crushing effect of the grinding body on the material, which helps to improve the grinding efficiency of the mill, increase production, and reduce metal consumption. However, in the existing liners, the installation between the liners is not firm enough, and they will deviate during operation, affecting the liner protection of the ball mill. Therefore, a composite ball mill liner is proposed.

[0003] For example, a Chinese patent with publication number CN202199390U discloses a ball mill composite liner, including a plate body, a mounting hole on the plate body, and a metal bottom layer and a plastic layer composited on the metal bottom layer. The ball mill composite liner of the utility model has the advantages of high strength, good wear resistance, and not easy to break or crack.

[0004] The above patent has the following problems:

[0005] Compared with the prior art, the liner plates are not firmly installed, and vibration may occur when the ball mill is working, causing the liner plates to move and produce gaps, affecting the liner plates to protect the inner wall of the ball mill and reducing the service life of the ball mill. In addition, the liner plates in the prior art are not made of good materials, are not wear-resistant and corrosion-resistant, and have poor protection performance. Long-term use will reduce the service life of the liner plates and increase the production cost of the liner plates. In view of this, we propose a composite ball mill liner plate. Utility Model Content

[0006] The purpose of the utility model is to provide a composite ball mill liner to solve the above-mentioned technical problems, so as to achieve the effect of firm installation and sufficiently good material.

[0008] Based on the above structure, the liner body is fixed to the inner wall of the cylinder by a fixing bolt, and then the top of the fixing bolt can be protected by a protective sleeve to prevent the fixing bolt from being damaged during stirring of the ball mill. Then, the limiting groove can be used in combination with the fixing block for fixing, so that multiple liner bodies can be fixed, and then the limiting groove can be protected by a protective ring to prevent wear of the fixing block. When used in combination, the fixing bolt and the fixing block can fix the liner bodies, and when vibration occurs, the liner bodies will not move, and no gaps will be generated, which will not affect the liner body from protecting the inner wall of the cylinder, thereby increasing the service life of the cylinder. Then, the liner body is used to protect the inner wall of the cylinder, and then the wear-resistant layer can be used to enhance the wear resistance of the liner body, and then the manganese steel layer can be used to enhance the strength of the liner body, and then the corrosion-resistant layer can be used to enhance the corrosion resistance of the liner body. When used in combination, the material of the liner body can be good enough, wear-resistant and corrosion-resistant, with good protective performance, and long-term use will not reduce the service life of the liner body, thereby reducing the manufacturing cost of the liner body.

[0010] Preferably, a cylinder is fixedly installed at the bottom of the sound insulation layer to limit the device.

Then, a plurality of liner bodies can be fixed by using a limiting groove in combination with a fixing block, and a protective ring can be used to protect the limiting groove to prevent wear of the fixing block. When used together, the fixing bolt and the fixing block can fix the liner bodies. When vibration occurs, the liner bodies will not move, no gaps will be generated, and the liner body will not affect the inner wall of the cylinder, thereby increasing the service life of the cylinder.
