Description

Technical Field

[0001] This utility model relates to a particle mill, and more particularly to a particle mill for mineral processing. Background Technology

[0002] A ball mill (also known as a grinding mill or ball mill) is a type of equipment commonly used in the mineral processing industry. It is widely used in minerals, metals, chemicals, building materials and other fields, especially in the fine and ultrafine grinding of ores. Its main function is to crush coarse ores into smaller particles for subsequent beneficiation, smelting or other processing.

[0003] In existing technologies, such as the ball mill with publication number CN222305964U that improves material feeding efficiency, after the mixing is completed, the mixing component is raised by the cylinder. It first leaves the ball mill barrel, then drives the protective sleeve on the inner wall of the ball mill barrel to leave, and finally drives the ball mill barrel to rotate, causing the ball mill barrel to tilt. In this way, all the material and steel balls in the barrel can be poured out, thereby improving the material feeding efficiency.

[0004] However, it also has some shortcomings. For example, its grinding barrel is connected to the frame via a rotating shaft, making it inconvenient to remove the grinding barrel from the frame when it needs to be replaced. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a mineral processing particle mill that is easy to disassemble and assemble.

[0006] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows: a particle mill for mineral processing, including a base, a support frame on the base, a grinding barrel in the support frame, a rotating shaft rotatably connected to the support frame on the left and right sides of the outer wall of the grinding barrel, a stirring assembly in the grinding barrel, a connecting assembly rotatably connected to the rotating shaft on the inner walls of the left and right sides of the support frame, each connecting assembly including a connecting cylinder, the connecting cylinder being rotatably installed in the support frame, the connecting cylinder being open on the side near the grinding barrel; an abutment plate slidably installed in the connecting cylinder, the abutment plate having a polygonal connecting post on the side wall near the grinding barrel, the rotating shaft having a connecting hole matching the connecting post on the side wall; and a spring installed in the connecting cylinder, one end of the spring being connected to the abutment plate, and the other end of the spring being connected to the inner wall of the connecting cylinder.

[0007] A further preferred embodiment of the present invention is as follows: a first drive motor is provided on the outer wall of the support frame, the output end of the first drive motor passes through the support frame and is connected to the connecting cylinder, a plurality of limiting grooves are provided on the inner wall of the connecting cylinder, and a limiting block is slidably provided in each limiting groove, and the limiting block is connected to the abutment plate at the end away from the limiting groove.

[0008] A further preferred embodiment of this utility model is as follows: a bearing is sleeved on the connecting cylinder, the inner ring of the bearing is fixedly connected to the outer wall of the connecting cylinder, and the outer ring of the bearing is fixedly connected to the support frame.

[0009] A further preferred embodiment of this utility model is as follows: the top of the grinding barrel is open, the top of the grinding barrel is provided with a barrel cover that matches the top of the grinding barrel, the top of the support frame is provided with a telescopic device, and the telescopic end of the telescopic device is connected to the barrel cover.

[0010] A further preferred embodiment of this utility model is: a wear-resistant sleeve matching the inner wall of the grinding barrel is provided in the grinding barrel, and a positioning groove matching the wear-resistant sleeve is provided at the bottom of the grinding barrel.

[0011] A further preferred embodiment of the present invention is as follows: the stirring assembly includes a stirring rod installed in the grinding barrel and a second drive motor installed at the bottom of the grinding barrel, wherein the output end of the second drive motor passes through the grinding barrel and is connected to the stirring rod.

[0012] A further preferred embodiment of this utility model is: the wear-resistant sleeve is composed of multiple arc-shaped plates spliced ​​together, one side of the arc-shaped plate is provided with a connecting block, and the other side of the arc-shaped plate is provided with a connecting groove that matches the connecting block.

[0013] A further preferred embodiment of this utility model is that a sealing sleeve made of elastic material is provided between the connecting groove and the connecting block.

[0014] Compared with the prior art, the advantages of this utility model are that when the connecting column retracts into the connecting cylinder, the connecting column disengages from the connecting hole on the rotating shaft, thereby allowing the grinding barrel to be removed from the support frame. This facilitates the disassembly and replacement of the grinding barrel. To ensure the firmness of the connection between the connecting column and the rotating shaft, a spring is provided in the connecting cylinder, with one end connected to the abutment plate and the other end connected to the inner wall of the connecting cylinder. When the connecting column connects to the connecting hole on the rotating shaft, the spring can push the abutment plate and the connecting column together to move towards the rotating shaft. This can prevent the problem of the connecting column disengaging from the rotating shaft during use, thus ensuring the reliability of the connection between the connecting column and the rotating shaft. Furthermore, the polygonal arrangement of the connecting column and the connecting hole can prevent slippage between the connecting column and the connecting hole when the grinding barrel rotates, thereby further ensuring the reliability of the connection between the connecting assembly and the grinding barrel.

[0027] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings. Those skilled in the art will appreciate that these descriptions are merely descriptive and exemplary and should not be construed as limiting the scope of protection of the present invention.

[0028] It should be noted that similar labels in the following figures indicate similar items; therefore, once an item is defined in one figure, it may not be further defined and explained in subsequent figures.

[0029] This embodiment mainly describes the structure of a particle mill for mineral processing, as follows:

[0030] like Figures 1-10 As shown, a mineral processing pellet mill includes a base 1 and a support frame 2 mounted on the base 1. A grinding barrel 3 with an open top is disposed in the support frame 2. A rotating shaft 4, rotatably connected to the support frame 2, is disposed on the left and right sides of the outer wall of the grinding barrel 3, allowing the grinding barrel 3 to rotate within the support frame 2. A stirring assembly for stirring is disposed in the grinding barrel 3. The stirring assembly includes a stirring rod 9 installed in the grinding barrel 3 and a second drive motor 6 installed at the bottom of the grinding barrel 3. The output end of the second drive motor 6 passes through the grinding barrel 3 and is connected to the stirring rod 9. When the pellet mill is working, grinding media (such as ceramic particles) and the mineral to be ground are added to the grinding barrel 3 through the opening at the top of the grinding barrel 3. Then, the second drive motor 6 is started to rotate the stirring rod 9 in the grinding barrel 3. The rotating stirring rod 9 can stir the grinding media and the mineral to be ground until the mineral is ground. After the mineral is ground, the grinding barrel 3 is rotated to tilt it in the support frame 2 until all the grinding media and mineral in the grinding barrel 3 can be poured out.

[0031] To prevent minerals or grinding media from splashing at the opening of the grinding barrel 3 during operation, a barrel cover 7 matching the opening of the top of the grinding barrel 3 is provided on the top of the grinding barrel 3. At the same time, to reduce the workload of the workers, a telescopic device 8 connected to the barrel cover 7 is provided on the top of the support frame 2. Thus, the barrel cover 7 can be moved away from or closer to the grinding barrel 3 by using the telescopic device 8. When the telescopic end of the telescopic device 8 extends, the barrel cover 7 connected to the telescopic end of the telescopic device 8 moves closer to the opening at the top of the grinding barrel 3 until the opening at the top of the grinding barrel 3 is closed. When the telescopic end of the telescopic device 8 retracts, the barrel cover 7 connected to the telescopic end of the telescopic device 8 moves away from the opening at the top of the grinding barrel 3 until the opening at the top of the grinding barrel 3 is open.

[0032] To facilitate the removal of the grinding barrel 3 from the support frame 2, a connecting assembly connected to the rotating shaft 4 is rotatably mounted on the inner walls of the left and right sides of the support frame 2. Each connecting assembly includes a connecting cylinder 11 rotatably mounted within the support frame 2, with an opening on the side near the grinding barrel 3. A contact plate 12 slides within the connecting cylinder 11, and a polygonal connecting post 13 is located on the side wall of the contact plate 12 near the grinding barrel 3. A connecting hole 41 matching the connecting post 13 is provided on the side wall of the rotating shaft 4, and the rotating shaft 4 connects to the connecting post 13 through the connecting hole 41. When the connecting post 13 retracts into the connecting cylinder 11, it disengages from the connecting hole 41 on the rotating shaft 4, allowing the grinding barrel 3 to be removed from the support frame. The grinding barrel 3 is removed from the 2nd part, which facilitates its disassembly and replacement. To ensure the firmness of the connection between the connecting post 13 and the rotating shaft 4, a spring is provided in the connecting cylinder 11, with one end connected to the abutment plate 12 and the other end connected to the inner wall of the connecting cylinder 11. When the connecting post 13 is connected to the connecting hole 41 on the rotating shaft 4, the spring can push the abutment plate 12 and the connecting post 13 to move towards the rotating shaft 4. This can prevent the connecting post 13 from separating from the rotating shaft 4 during use, thus ensuring the reliability of the connection between the connecting post 13 and the rotating shaft 4. The connecting post 13 and the connecting hole 41 are polygonal, which can prevent the connecting post 13 from slipping when the grinding barrel 3 rotates, thus further ensuring the reliability of the connection between the connecting assembly and the grinding barrel 3.

[0033] When the grinding barrel 3 is removed from the support frame 2, the grinding barrel 3 is first opened. Then, the operator controls the grinding barrel 3 to move left or right in the support frame 2. As the grinding barrel 3 moves, one side of the grinding barrel 3 moves closer to the connecting component on the support frame 2, while the other side moves away from the connecting component on the support frame 2. In this way, the rotating shaft 4 on the side of the grinding barrel 3 that is close to the connecting component can push the connecting post 13 along with the abutment plate 12 into the connecting cylinder 11 as the grinding barrel 3 moves. In this way, the rotating shaft 4 on the side of the grinding barrel 3 that is away from the support frame 2 can separate from the connecting post 13 in the connecting component. Then, the separated rotating shaft 4 and connecting post 13 are adjusted so that they are no longer aligned. Then the grinding barrel 3 is moved again, and this time the direction of movement of the grinding barrel 3 is opposite to the previous direction of movement, until the connecting post 13 and the rotating shaft 4 are separated. This completes the operation of removing the grinding barrel 3 from the support frame 2.

[0034] When installing the grinding barrel 3 onto the support frame 2, the operator first moves the grinding barrel 3 into the support frame 2, then moves the grinding barrel 3 towards the side of the support frame 2 where the connecting component is located, aligning the rotating shaft 4 on the grinding barrel 3 with the connecting post 13 on the support frame 2. The grinding barrel 3 is then moved further until the rotating shaft 4 can connect with the connecting post 13 through the connecting hole 41. The grinding barrel 3 is then moved again, this time in the opposite direction to the previous movement, until the rotating shaft 4 on the grinding barrel 3 is connected with the connecting post 13. This completes the operation of installing the grinding barrel 3 into the support frame 2. The connecting component facilitates the removal of the grinding barrel 3 from or installation into the support frame 2.

[0035] Furthermore, to eliminate the need for workers to rotate the grinding drum 3 when emptying the minerals, a first drive motor 5 is installed on the outer wall of the support frame 2. The output end of the first drive motor 5 passes through the support frame 2 and connects to the connecting cylinder 11. Thus, when the grinding drum 3 needs to be rotated, the first drive motor 5 can be activated, causing its output end to rotate the connecting cylinder 11 within the support frame 2. This also prevents the abutment plate 12 installed in the connecting cylinder 11 from impacting the rotation of the connecting cylinder 11. To prevent slippage, multiple limiting grooves 111 are provided on the inner wall of the connecting cylinder 11. At the same time, a limiting block 121 connected to the abutment plate 12 is slidably provided in each limiting groove 111. Thus, when the connecting cylinder 11 rotates, the abutment plate 12 installed in the connecting cylinder 11 also rotates. In order to ensure the smooth rotation of the connecting cylinder 11 in the support frame 2, a bearing 14 is sleeved on the connecting cylinder 11. The inner ring of the bearing 14 is fixedly connected to the outer wall of the connecting cylinder 11, and the outer ring of the bearing 14 is fixedly connected to the support frame 2.

[0036] Furthermore, in order to extend the service life of the grinding barrel 3, a wear-resistant sleeve 10 matching the inner wall of the grinding barrel 3 is provided in the grinding barrel 3. At the same time, a positioning groove 31 matching the wear-resistant sleeve 10 is opened at the bottom of the grinding barrel 3, and the bottom of the wear-resistant sleeve 10 is located in the positioning groove 31. In addition, to facilitate the replacement of the wear-resistant sleeve 10, the wear-resistant sleeve 10 is spliced ​​from multiple arc-shaped plates 101. In order to facilitate the splicing of the arc-shaped plates 101, a connecting block 102 is provided on one side of the arc-shaped plate 101, and a connecting groove 103 matching the connecting block 102 is provided on the other side of the arc-shaped plate 101. In order to ensure the sealing of the splicing of multiple arc-shaped plates 101, a sealing sleeve 104 made of elastic material is provided between the connecting groove 103 and the connecting block 102.
