Description

Technical Field

[0001] The utility model relates to the technical field of ball mill liners, and particularly relates to a ball mill liner with a wear-resistant structure. Background Art

[0002] The ball mill liner is used to protect the cylinder body from the direct impact and friction of grinding media and materials. At the same time, different forms of liners can be used to adjust the movement state of the grinding media to enhance the crushing effect of the grinding media on the materials, which helps to improve the grinding efficiency of the mill, increase the output, and reduce the metal consumption.

[0003] The wear resistance of the liner refers to the ability of the liner material to resist wear and maintain its original shape and performance when subjected to wear. In mechanical equipment such as ball mills and crushers, the liner is one of the key vulnerable parts, and its wear resistance is directly related to the service life, production efficiency and cost of the equipment. The wear resistance of the liner is achieved through appropriate materials and the design of the liner body structure. However, after long-term use, the impact force of the grinding media and materials on the liner body will cause wear on the surface of the liner body, resulting in a decrease in the wear resistance of the liner, and thus shortening its service life. Summary of the Utility Model

[0012] (III) Beneficial effects

[0013] 1. By setting the protection plate and cooperating with the rubber bumps, when installing the lining plate, the protection plate is slidably connected inside the installation groove and the connection groove through the T-shaped plate. At this time, the lining plate is installed inside the ball mill. When the ball mill works, the grinding media and materials contact the rubber bumps and the protection plate. The protection plate is made of rubber, and the rubber bumps and the protection plate have a certain elasticity. When the grinding media and materials impact the lining plate, the rubber bumps and the protection plate produce a certain deformation, reducing the impact force of the grinding media and materials on the lining plate body, thus playing a buffering role, reducing the wear of the lining plate body, and prolonging the service life of the lining plate.

[0014] 2. By setting the clamping groove and cooperating with the fixing bolt, when the protection plate and the rubber bumps are damaged, the connection between the bolt and the ball mill is released. At this time, the lining plate can be disassembled. Then push the protection plate to release the connection between the T-shaped plate and the installation groove. At this time, rotate the fixing bolt to release the connection between the fixing bolt and the threaded hole. Then pull the protection plate to release the connection between the T-shaped plate and the clamping groove. At this time, the connection between the protection plate and the T-shaped plate is released, and the protection plate is disassembled. The disassembly process of the protection plate is simple to facilitate the replacement of the damaged protection plate of the lining plate without installing a new lining plate, thus reducing material consumption.

[0022] By providing a ball mill liner with a wear-resistant structure in the embodiments of the present application, the technical problem that after long-term use, the impact force of the grinding body and the material on the liner body 1 will cause wear on the surface of the liner body 1, resulting in a decrease in the wear resistance of the liner and thus a shortening of its service life is effectively solved.

[0023] Embodiment

[0024] Such as Figure 1 , Figure 2 , Figure 3 , Figure 4 And Figure 5 , the technical solution in the embodiments of the present application effectively solves the technical problem that after long-term use, the impact force of the grinding body and the material on the liner body 1 will cause wear on the surface of the liner body 1, resulting in a decrease in the wear resistance of the liner and thus a shortening of its service life. The general idea is as follows:

[0025] In view of the problems existing in the prior art, the utility model provides a ball mill liner with a wear-resistant structure. The ball mill liner with a wear-resistant structure includes a liner body 1. Two connecting holes 2 are opened on the outside of the liner body 1. A protection mechanism is arranged on the outside of the liner body 1. The protection mechanism includes mounting grooves 3, connecting grooves 15, T-shaped plates 5, protection plates 6 and rubber bumps 8. There are two mounting grooves 3, and the two mounting grooves 3 are respectively opened at both ends of the liner body 1. There are two connecting grooves 15, and the two connecting grooves 15 are respectively opened on the upper surface of the liner body 1. The connecting grooves 15 communicate with the mounting grooves 3. There are two T-shaped plates 5, and the T-shaped plates 5 are slidably connected inside the mounting grooves 3 and the connecting grooves 15. The protection plate 6 is arranged on the upper surfaces of the two T-shaped plates 5. The protection plate 6 is attached to the surface of the liner body 1. There are several rubber bumps 8, and several rubber bumps 8 are fixedly installed on the side of the protection plate 6 away from the liner body 1. Two through holes 4 are opened on the outside of the protection plate 6, and the through holes 4 communicate with the inside of the connecting holes 2. By setting the protection plate 6 and cooperating with the rubber bumps 8, when installing the liner, the protection plate 6 is slidably connected inside the mounting grooves 3 and the connecting grooves 15 through the T-shaped plates 5. At this time, the liner is installed in the ball mill. At this time, the bolt enters the connecting hole 2 opened on the liner through the through hole 4, and then the bolt is pushed to the outside of the ball mill. At this time, the nut can be threadedly connected to the outside of the bolt. At this time, the installation of the liner is completed. When the ball mill is working, the grinding media and the material contact the rubber bumps 8 and the protection plate 6. The protection plate 6 is made of rubber, and the rubber bumps 8 and the protection plate 6 have a certain elasticity. When the grinding media and the material impact the liner, the rubber bumps 8 and the protection plate 6 produce a certain deformation, reducing the impact force of the grinding media and the material on the liner body 1, thus playing a buffering role, thereby reducing the wear of the liner body 1 and prolonging the service life of the liner.

[0026] Clamping grooves 10 are opened at both ends of the protection plate 6. The ends of the T-shaped plates 5 away from the mounting grooves 3 are clamped inside the clamping grooves 10, which is convenient for the disassembly and assembly of the protection plate 6. Two through holes 9 are opened at both ends of the protection plate 6. A fixing bolt 11 is movably connected inside each through hole 9. Threaded holes 12 are opened at both ends of each T-shaped plate 5 away from the mounting grooves 3. The fixing bolt 11 is threadedly connected inside the threaded holes 12, improving the installation stability of the protection plate 6. A placing hole 13 is opened at one end of each through hole 9 away from the threaded hole 12. By setting the clamping grooves 10 and cooperating with the fixing bolts 11, when the protection plate 6 and the rubber bumps 8 are damaged, the connection between the bolt and the ball mill is released. At this time, the liner can be disassembled. At this time, the protection plate 6 is pushed to release the connection between the T-shaped plate 5 and the mounting groove 3. At this time, the fixing bolt 11 is rotated to release the connection between the fixing bolt 11 and the threaded hole 12. At this time, the protection plate 6 is pulled to release the connection between the T-shaped plate 5 and the clamping groove 10. At this time, the connection between the protection plate 6 and the T-shaped plate 5 is released. At this time, the protection plate 6 is disassembled. The disassembly process of the protection plate 6 is simple, facilitating the replacement of the damaged protection plate 6 of the liner without installing a new liner, thereby reducing material consumption.

[0027] One end of the fixing bolt 11 away from the threaded hole 12 is movably connected inside the placing hole 13 to prevent the fixing bolt 11 from affecting the installation of the lining plate. A gasket 7 is movably sleeved outside the fixing bolt 11, and the gasket 7 is located inside the placing hole 13 to increase the stability of the fixing bolt 11. A baffle 14 is fixedly installed inside each installation groove 3, and the baffle 14 fits on the surface of the T-shaped plate 5 to limit the position of the T-shaped plate 5 in the installation groove 3, eliminating the need for workers to adjust the position of the protection plate 6 when connecting the protection plate 6 and the lining plate.

[0028] Working principle:

[0029] First step, the protection plate 6 is snap-connected to the outside of the T-shaped plate 5 through the card slot 10. At this time, the fixing bolt 11 is passed through the through hole 9, and then the fixing bolt 11 is rotated to connect the fixing bolt 11 with the threaded hole 12. At this time, the connection between the protection plate 6 and the T-shaped plate 5 is completed. When installing the lining plate, the protection plate 6 is slidably connected to the inside of the installation groove 3 and the connection groove 15 through the T-shaped plate 5. At this time, the lining plate is installed in the ball mill. At this time, the bolt enters the connection hole 2 opened on the lining plate through the opening 4, and then the bolt is pushed to the outside of the ball mill. At this time, the nut can be threadedly connected to the outside of the bolt. At this time, the installation of the lining plate is completed. There are multiple lining plates in the ball mill, and adjacent lining plates are in contact with each other, thus preventing the lateral movement of the protection plate 6;

[0030] Second step, when the ball mill is working, the grinding media and the material come into contact with the rubber bumps 8 and the protection plate 6. The protection plate 6 is made of rubber, and the rubber bumps 8 and the protection plate 6 have a certain elasticity. When the grinding media and the material impact the lining plate, the rubber bumps 8 and the protection plate 6 generate a certain deformation, reducing the impact force of the grinding media and the material on the lining plate body 1, thus playing a buffering role, reducing the wear of the lining plate body 1, and extending the service life of the lining plate.

[0031] Finally, it should be noted that: Obviously, the above embodiments are only examples for clearly illustrating the present invention, and are not limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or variations can be made on the basis of the above description. It is not necessary and impossible to enumerate all the implementation manners here. And the obvious changes or variations derived therefrom are still within the protection scope of the present invention.
