Description

Technical Field

[0001] This utility model relates to the field of ball mill technology, and in particular to a tilting ball mill. Background Technology

[0002] A ball mill is a key piece of equipment used for material grinding, widely applied in industries such as cement, silicate products, new building materials, refractory materials, fertilizers, ferrous and non-ferrous metal ore beneficiation, and glass and ceramics. It can grind large materials into fine powder, laying a solid foundation for subsequent production processes. The grinding media are lifted to a certain height by the liners on the inner wall of the mill before falling, violently impacting the material. Simultaneously, the friction and rolling between the media and the material further refine the material.

[0003] Meanwhile, traditional ball mills, due to their fixed horizontal or vertical structural design, face significant challenges in the loading and unloading processes. These devices typically lack flexibility and cannot easily adjust the position of the cylinder to facilitate material entry and exit. Therefore, in actual operation, additional auxiliary equipment or a large amount of manual labor is often required to complete the loading and unloading tasks. Moreover, material adhering to the cylinder wall is difficult to completely remove. This phenomenon is mainly due to the centrifugal force generated during the grinding process and the viscosity of the material itself. Residual material not only reduces production efficiency because it requires extra time and effort to clean, but it can also lead to cross-contamination between different batches of material, affecting product quality. Utility Model Content

[0004] To overcome the problems of traditional ball mills, which require additional equipment or manual handling for loading and unloading due to their fixed horizontal or vertical structure, resulting in low efficiency and safety hazards, and the difficulty in completely discharging materials after the grinding process due to their adhesion to the cylinder wall, this utility model provides a tilting ball mill.

[0005] The technical solution is as follows: A tilting ball mill includes a mounting base, a fixed frame, a mounting plate, a sliding groove, a rotating groove, a rotating column, a support groove, a sliding column, a mounting bracket, a connecting bracket, a rotating disk, and a cylinder; a fixed frame is mounted at the center of the upper surface of the mounting base, a mounting plate is mounted at the upper end of the fixed frame, a support groove is opened at the rear end of the lower surface of the mounting plate, two sets of sliding grooves are symmetrically opened on both sides inside the support groove, a rotating groove is opened at the front end of the lower surface of the mounting plate, a cylinder for providing power to lift the ball mill is mounted at the front end inside the fixed frame, a mounting bracket is mounted at the piston end of the cylinder, a rotating column located inside the support groove is mounted in the cavity of the upper surface of the mounting bracket, two sets of sliding columns symmetrically mounted on both sides of the rotating column are slidably connected to the sliding groove for maintaining stability when the ball mill is lifted, a connecting bracket is mounted at the front end of the upper surface of the fixed frame, and a rotating disk for auxiliary rotation when lifted is clamped and mounted inside the connecting bracket.

[0006] Furthermore, the ball mill body is mounted at the center of the upper end of the mounting plate, a large gear is mounted around the outer rear end of the ball mill body, and a support frame is mounted on the upper surface of the mounting plate near the corner.

[0007] Furthermore, a reducer connected to a pinion gear is mounted on the upper surface of the mounting plate at the rear end of the support frame, and a support plate fixedly connected to the mounting plate is mounted at the rear end of the reducer.

[0008] Furthermore, a rotating motor connected to a reducer is installed on the upper surface of the support plate, and a cover plate is fastened to the front end of the ball mill body.

[0009] Furthermore, a buckle plate is installed at the connection between the cover plate and the ball mill body, and multiple sets of fixing brackets are installed at the lower end of the ball mill body to be fixedly connected to the mounting plate. The side surface of the mounting plate is equipped with air grooves corresponding to the cylinders.

[0010] Furthermore, a fixing column is installed in the cavity at the front end of the fixing frame, and a positioning frame that connects to the main body of the ball mill when tilted is installed at the front end of the fixing column. A connecting spring is installed between the positioning frame and the fixing column.

[0011] Furthermore, a spring damper is provided inside the connecting spring, and a telescopic rod connected to the positioning frame is installed around the outside of the fixing column.

[0012] Furthermore, a fixing plate is installed at the front corner of the upper surface of the mounting base, and a vibration motor is installed at the upper side surface of the fixing plate.

[0013] The beneficial effects are as follows: This utility model enables the ball mill body to be lifted by power provided by the cylinder, and the sliding groove, rotating groove and other structures ensure stability during the lifting process. This eliminates the need for additional auxiliary equipment or a large amount of manual labor during loading and unloading, greatly improving the convenience of operation and reducing safety hazards caused by handling heavy objects. The design of the vibration motor and eccentric wheel, which starts vibration after the ball mill has finished grinding, can effectively loosen the material and reduce the amount of material adhering to the cylinder wall, thereby simplifying the unloading process, improving the thoroughness of material discharge, reducing the impact of residual material on subsequent batches, and ensuring the purity and quality consistency of the product. The transmission system composed of large gear, small gear and reducer ensures that the ball mill runs stably at the set speed, improving grinding efficiency. The positioning frame, connecting spring, telescopic rod and spring damper work together to absorb and buffer the impact and vibration generated during the operation of the equipment, protecting the internal structure from damage.

[0020] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0021] Among the currently discovered feasible technologies, the following are described:

[0022] Ball mills, as crucial material grinding equipment, are widely used in various industrial fields, including but not limited to cement, silicate products, new building materials, refractory materials, fertilizer production, ferrous and non-ferrous metal beneficiation, and glass and ceramics. Their main function is to crush and grind large raw materials into fine powder, providing ideal particle sizes for subsequent production processes, thus ensuring the quality of the final product. Inside the ball mill's cylinder, a certain amount of grinding media (such as steel balls, ceramic balls, or other suitable materials) is contained. During the cylinder's rotation, these media are lifted to a certain height by centrifugal force and then fall, violently impacting the internal material. This impact effectively crushes larger particles, making them smaller. Furthermore, with the continuous rotation of the cylinder, the friction and rolling action between the grinding media and between them and the material further refines the material until the desired particle size distribution is achieved. To protect the inner wall of the cylinder from wear, liners are usually installed on the inner wall. This not only extends the equipment's service life but also allows for... By optimizing liner design to improve grinding efficiency, the working principle of ball mills determines their indispensability in various production processes requiring fine powders. For example, in cement production, ball mills are used to grind limestone, clay, and other additives to prepare raw materials; in ceramics and glass manufacturing, they are used to grind raw materials to ensure the finished product has uniform quality; in metal beneficiation, ball mills are used to process ores to extract valuable metal components. Furthermore, modern ball mill designs also consider factors such as energy efficiency, environmental requirements, and ease of operation. For instance, the design of tilting ball mills allows for easier loading, unloading, and maintenance, while improving production efficiency and safety. Through the adoption of advanced control technology, precise adjustment of ball mill operating parameters can be achieved, further optimizing the production process, reducing energy consumption, and minimizing environmental pollution, meeting the demands of modern society for sustainable development. In short, as a key piece of equipment in basic industries, the performance of ball mills directly affects the production quality and economic benefits of numerous industries.

[0023] First, the limited operational flexibility is a major drawback of traditional ball mills. These machines are typically installed in a fixed position, making material loading and unloading particularly inconvenient, especially for large or heavy-duty ball mills. Because they are difficult to move or tilt to facilitate material entry and exit, the lack of flexible angle adjustment forces operators to rely on auxiliary equipment such as elevators or conveyors, or to rely on significant manual labor for loading and unloading. This method is not only time-consuming and labor-intensive, increasing labor costs, but also poses safety hazards when handling heavy objects, such as the risk of worker injury or equipment damage, thus reducing overall work efficiency. Secondly, material residue is also a problem for traditional ball mills. A significant challenge facing ball mills is that during the grinding process, materials tend to adhere to the cylinder wall due to centrifugal force and their own stickiness, making complete discharge difficult. This not only reduces production efficiency, as it requires extra time and effort to clean residual material, but also can lead to cross-contamination between different batches of materials. This is particularly problematic in industries with extremely stringent requirements for purity and quality consistency, such as pharmaceuticals, food processing, and fine chemicals. Any degree of cross-contamination can have serious consequences, affecting the market acceptance and safety of the final product. For example, in pharmaceutical manufacturing, even trace impurities can alter the active ingredients of a drug, leading to poor therapeutic effects or even side effects. In the food industry, cross-contamination can cause food safety issues, threatening consumer health.

[0024] This new type of tilting ball mill significantly improves upon the limitations of traditional ball mills in terms of operational flexibility and material handling by introducing a series of innovative designs. First, it adopts a cylinder-driven lifting and rotation mechanism, which allows the main body of the ball mill to be flexibly adjusted in angle according to actual needs. This means that during loading and unloading, the cylinder can be tilted to the optimal position, greatly simplifying the operation of these steps. Operators no longer need to rely on additional auxiliary equipment or perform heavy manual labor to complete the material loading and unloading, thereby significantly improving work efficiency and reducing labor costs. In addition, this design also reduces safety hazards during operation and improves overall safety performance. At the same time, the new ball mill is equipped with a vibration motor, which is an important improvement measure to address the problem of material residue. After grinding, starting the vibration motor generates vibration, effectively loosening the material adhering to the cylinder wall. This vibration makes it easier to discharge the previously difficult-to-remove residual material, ensuring a more thorough discharge effect, reducing material waste, and avoiding cross-contamination between different batches of material.

[0025] like Figure 1 - Figure 5As shown, a tilting ball mill includes a mounting base 1, a fixed frame 2, a mounting plate 3, a sliding groove 14, a rotating groove 15, a rotating column 16, a support groove 17, a sliding column 18, a mounting bracket 19, a connecting bracket 20, a rotating disk 21, and a cylinder 22. A fixed frame 2 is mounted at the center of the upper surface of the mounting base 1. A mounting plate 3 is mounted on the upper end of the fixed frame 2. A support groove 17 is formed at the rear end of the lower surface of the mounting plate 3. Two sets of sliding grooves 14 are symmetrically formed on both sides inside the support groove 17. A rotating groove 15 is formed at the front end of the lower surface of the mounting plate 3. A cylinder 22 for providing power to lift the ball mill is installed at the front end of the fixed frame 2. A mounting bracket 19 is installed at the piston end of the cylinder 22. A rotating column 16 located inside the support groove 17 is installed in the cavity on the upper surface of the mounting bracket 19. Two sets of sliding columns 18 are symmetrically installed on both sides of the rotating column 16 and are slidably connected to the sliding groove 14 to keep the ball mill stable when it is lifted. A connecting bracket 20 is installed at the front end of the upper surface of the fixed frame 2. A rotating disk 21 that is rotatably connected to the rotating groove 15 is clamped inside the connecting bracket 20 for auxiliary rotation when lifted.

[0026] The ball mill body 9 is mounted at the center of the upper end of the mounting plate 3. A large gear 10 is mounted around the outer rear end of the ball mill body 9. A support frame 4 is mounted on the upper surface of the mounting plate 3 near the corner. The ball mill body 9 and the large gear 10 can effectively transmit the power of the rotating motor 8 to the ball mill, ensuring stable operation during the grinding process. A reducer 6, which is connected to the pinion 5, is mounted on the upper surface of the mounting plate 3 at the rear end of the support frame 4. A support plate 7, which is fixedly connected to the mounting plate 3, is mounted at the rear end of the reducer 6. The support frame 4 provides additional structural support, while the reducer 6, mounted near the corner, is connected to the pinion 5, which can precisely control the speed of the ball mill and improve the grinding efficiency. To improve efficiency and product quality, a rotating motor 8 connected to a reducer 6 is mounted on the upper surface of the support plate 7. A cover plate 12 is fastened to the front end of the ball mill body 9. The support plate 7 is fixed to the rear end of the reducer 6, providing a stable mounting platform for the rotating motor 8 and ensuring the smoothness and reliability of power transmission. A buckle plate 11 is installed at the connection between the cover plate 12 and the ball mill body 9. Multiple sets of fixing brackets 13 are installed at the lower end of the ball mill body 9 and are fixedly connected to the mounting plate 3. An air groove 24 corresponding to the cylinder 22 is installed on the side surface of the mounting plate 3. The cover plate 12 is fastened to the front end of the ball mill body 9, and the buckle plate 11 enhances the sealing to prevent material leakage, while also facilitating maintenance and cleaning.

[0027] The rotating motor 8 is connected to the pinion 5 via the reducer 6, which precisely transmits the rotational motion to the large gear 10. The large gear 10 is mounted around the outer rear end of the ball mill body 9, thereby driving the ball mill body 9 to rotate. The reducer 6 is located at the rear end of the support frame 4 and is fixed to the mounting plate 3 via the support plate 7. It not only provides a stable platform for the rotating motor 8 but also ensures the smoothness and reliability of power transmission. The ball mill body 9 is mounted at the upper center of the mounting plate 3 and is fixed by multiple sets of fixing brackets 13, ensuring the stability and safety of the ball mill body 9. The cover plate 12 is fastened to the front end of the ball mill body 9 and the sealing is enhanced by the fastening plate 11 to prevent material leakage and facilitate maintenance and cleaning. When loading or unloading operations are required, the cylinder 22 is activated, and the piston end pushes the mounting frame 19 upward. The rotating column 16 on the mounting frame 19 and the sliding columns 18 symmetrically installed on both sides slide along the sliding groove 14 in the support groove 17 on the lower surface of the mounting plate 3, so that the ball mill body 9 can be raised smoothly. The connecting frame 20 at the front end of the fixed frame 2 holds and installs a rotating disk 21 that is rotatably connected to the rotating groove 15, which assists the ball mill body 9 in making appropriate rotational adjustments when it is raised. A fixing plate 23 is provided at the front corner of the upper surface of the mounting base 1, and a vibration motor 25 is installed on the upper side surface of the fixing plate 23. When the ball mill completes the grinding task, the vibration motor 25 starts and generates vibration through the eccentric wheel 26. The vibration is transmitted to the ball mill body 9 through the positioning frame 27, which helps to loosen the material, making it easier to discharge, reducing residue, and improving production efficiency.

[0028] Please see Figure 3 - Figure 4 A fixing column 28 is installed in the cavity at the front end of the fixing frame 2. A positioning frame 27, which connects to the ball mill body 9 when tilted, is installed at the front end of the fixing column 28. A connecting spring 29 is installed between the positioning frame 27 and the fixing column 28. Multiple sets of fixing frames 13 enhance the connection stability between the ball mill body 9 and the mounting plate 3. The air groove 24 is used in conjunction with the cylinder 22 to help achieve smooth lifting and angle adjustment of the ball mill. A spring damper is installed inside the connecting spring 29. A telescopic rod 30, which connects to the positioning frame 27, is installed around the outside of the fixing column 28. The connecting spring 29 of the spring damper and the telescopic rod 30 surrounding the fixed column 28 effectively absorb vibration, reduce equipment wear, and protect the internal structure from damage. A fixed plate 23 is installed at the front corner of the upper surface of the mounting base 1. A vibration motor 25 is installed at the upper side surface of the fixed plate 23. An eccentric wheel 26 connected to the positioning frame 27 is installed at the output end of the vibration motor 25. The vibration motor 25 installed on the fixed plate 23 generates vibration through the eccentric wheel 26, which helps to loosen the material, make the unloading more thorough, reduce residue, and improve production efficiency.

[0029] The fixed column 28 installed at the front cavity of the fixed frame 2 provides structural support, while the positioning frame 27 connected to the front end of the fixed column 28 is directly connected to the ball mill body 9 when tilted. This design ensures that the ball mill body 9 can be stably positioned when adjusting the angle or performing maintenance, avoiding unnecessary movement or displacement. The positioning frame 27 and the fixed column 28 are connected by a connecting spring 29, and a spring damper is installed inside. These components work together to absorb vibration and impact during the operation of the ball mill, reduce equipment wear caused by vibration, and protect the internal structure from damage. The telescopic rod 30 installed around the outside of the fixed column 28 further enhances the connection between the positioning frame 27 and the fixed column 28. To ensure the stability of the connection, when the ball mill body 9 tilts or vibrates, the telescopic rod 30 can automatically adjust its length according to the change in position, ensuring the stability and safety of the entire system. The cylinder pushes the mounting frame 19 upward through the piston end, realizing the lifting action of the ball mill body 9. At the same time, the side surface of the mounting plate 3 is equipped with an air groove 24 corresponding to the cylinder 22, which works in conjunction with the cylinder 22 to help realize the smooth lifting and angle adjustment of the ball mill. After the ball mill completes the grinding task, the vibration motor 25 is started, which generates vibration through the eccentric wheel 26. This vibration is transmitted to the positioning frame 27, which in turn affects the ball mill body 9, helping to loosen the material, making it easier to discharge, reducing residue, and improving production efficiency.
