Abstract
Description
Technical Field
[0001] This application belongs to the field of ball mill technology, and particularly relates to a ball mill. Background Technology
[0002] Ball mills, as core equipment for material grinding in mining, building materials, and chemical industries, have their operating efficiency directly related to the performance of their transmission system. In the existing structural design of ball mills, some models use belt drive to achieve the rotation of the cylinder. This transmission method transmits power through the friction between the belt and the pulley. Due to its relatively simple structure and convenient initial installation, it is used in some small or low-load grinding scenarios.
[0003] However, as industrial production demands increasingly higher grinding efficiency, operational stability, and wider applicability of ball mills, the inherent defects of belt drives have become increasingly apparent. They are no longer sufficient to meet the needs of efficient and stable large-scale production. The characteristic of belt drives relying on friction to transmit power makes them prone to slippage during actual operation. When fluctuations in the amount of material processed by the ball mill cause changes in the load on the mill cylinder, the friction between the belt and pulleys easily becomes unbalanced, leading to slippage. This not only causes interruptions or instability in power transmission but also results in fluctuations in the cylinder's rotational speed. The instability of the cylinder's rotational speed directly affects the impact and grinding force of the grinding media (such as steel balls) on the material, resulting in uneven fineness of the ground products, fluctuating output, and difficulty in ensuring consistent product quality.
[0004] Meanwhile, the load-bearing capacity of belt drives is limited by the strength and friction of the belt itself. For ball mills with large throughput, heavy cylinders, or high grinding loads, the belts are unable to withstand the high torque transmission requirements, and are prone to stretching deformation or even breakage. As a wear part, the belt is in a state of friction and tension for a long time, and is affected by dust, humidity and other factors in the grinding environment, which can easily lead to aging, wear and cracking. Frequent belt inspections and tension adjustments and regular belt replacements are required, which increases the workload and maintenance costs for maintenance personnel. Improvements are needed in this regard. Utility Model Content
[0005] The purpose of this application is to provide a ball mill that can solve the above-mentioned problems.
[0006] The purpose of this application is to provide a ball mill, comprising: Support base; The cylinder is mounted on a support base, with one end being the feed inlet and the other end being the discharge outlet; A drive mechanism, connected to the cylinder and used to drive the cylinder to rotate, includes: The drive component is mounted on the support base; The first gear is located on the outer wall of the cylinder. The second gear is connected to the drive assembly and meshes with the first gear; The cylinder is rotatably mounted on a support base and rotates through the cooperation of a drive assembly, a second gear, and a first gear.
[0007] The ball mill described above uses a support base to support the cylinder, ensuring that the cylinder remains stable during rotation and preventing the cylinder from shaking due to unstable support, which would affect the grinding accuracy. The cylinder has a feed inlet at one end and a discharge outlet at the other end. The inside of the cylinder contains grinding media, and the material is fully in contact with the grinding media in the cylinder to achieve grinding, and is finally discharged from the storage port.
[0008] Meanwhile, the drive mechanism drives the cylinder to rotate through the meshing of the drive components, the second gear, and the first gear. Compared with belt drives, which are prone to slippage and have high power loss, gear meshing drives can avoid slippage, making power transmission more direct and stable, effectively reducing power loss, and ensuring that the cylinder speed remains stable. Moreover, the stable speed allows the impact of the grinding media on the material and the grinding force to be uniform, thereby ensuring uniform fineness of the ground products and stable output. This solves the problem of uneven product quality caused by speed fluctuations in belt drives. Furthermore, gear drives have a stronger load-bearing capacity and can be adapted to grinding operations with larger loads, overcoming the limitation of belt drives in terms of applicable scenarios.
[0009] Furthermore, the driving component includes: The drive motor is mounted on the support base; The regulating box is mounted on the support base and connected to the drive motor; The connecting shaft has one end connected to the adjusting box and the other end connected to the second gear; It also includes an adjustment motor, which is connected to the adjustment box and used to adjust the gear.
[0010] Using the aforementioned drive assembly, the drive motor provides power for the rotation of the cylinder. After the regulating box is connected to the drive motor, the power is stably transmitted to the second gear through the connecting shaft, ensuring power transmission. The structure of connecting the regulating box at one end and the second gear at the other end further ensures the stability of power transmission. At the same time, the regulating motor is connected to the regulating box and used to adjust the gear. The gear can be adjusted according to the grinding requirements of different materials (such as material hardness and differences in required grinding fineness), thereby changing the output power of the drive assembly and the cylinder speed. This allows the ball mill to be adapted to grinding operations of various materials, improving the versatility of the equipment.
[0011] For example, for materials with high hardness, the motor can be adjusted to a higher gear to increase the cylinder speed and the impact force of the grinding media, ensuring that the material is fully ground; for materials with low hardness that require fine grinding, the gear can be lowered to reduce the speed to ensure the fineness of the grinding, thus solving the problem that belt drives cannot flexibly adjust the speed and the speed is prone to fluctuation, further improving the accuracy of the grinding operation.
[0012] Furthermore: the cylinder body is provided with mounting protrusions, and the first gear is mounted on the mounting protrusions.
[0013] An annular mounting protrusion is provided on the cylinder body, upon which the first gear is mounted. This protrusion positions the first gear, ensuring it remains coaxial with the cylinder body during installation. This prevents misalignment of the first gear, which could lead to mis-meshing with the second gear, thus avoiding abnormal wear and extending the gear's lifespan. Furthermore, the mounting protrusion strengthens the connection between the first gear and the cylinder body, preventing loosening or displacement even during high-speed rotation and under significant torque, ensuring long-term stable operation of the transmission system.
[0014] Furthermore, the first gear includes a mounting portion that mates with the mounting protrusion, a toothed portion that meshes with the second gear, and a reinforcing portion that connects the toothed portion and the mounting portion. The reinforcing portion is composed of a plurality of evenly distributed reinforcing ribs.
[0015] The first gear structure, with its mounting part and mounting protrusion, allows for docking and installation of the first gear with the cylinder, further enhancing the connection stability between the first gear and the cylinder and preventing relative slippage during operation. The toothed part meshes with the second gear, and its tooth design ensures tight and smooth meshing, reducing backlash and improving transmission efficiency. Furthermore, the reinforcing part connecting the toothed part and the mounting part consists of multiple evenly distributed reinforcing ribs. These ribs significantly improve the overall structural strength and torque resistance of the first gear, making it less prone to deformation or breakage when subjected to higher transmission torques. This allows it to withstand heavier grinding loads and extends its service life.
[0016] Furthermore, a protective cover is provided on the outside of the first gear, and the protective cover extends above the second gear and covers the second gear simultaneously.
[0017] By installing a protective cover on the outside of the first gear and extending it to cover the second gear simultaneously, the protective cover can effectively block dust and impurities in the grinding environment from entering the meshing area of the first and second gears. This prevents dust from adhering to the tooth surface and affecting meshing accuracy, or impurities from entering the meshing gap and causing abnormal wear of the gears, thereby protecting the gear transmission system and extending the service life of the gears.
[0018] Meanwhile, the protective cover encloses both gears, preventing operators from accidentally coming into contact with the rotating gears during equipment operation, thus improving equipment safety, eliminating safety hazards, ensuring that the gears are always in good working condition, and improving grinding quality and efficiency.
[0019] Furthermore, the cylinder is also provided with a replacement port, which is equipped with a sliding door and a handle.
[0020] By setting a replacement port on the cylinder, and a sliding door with a handle on the sliding door, the operator can easily open or close the sliding door, simplifying the operation process. When it is necessary to replace the grinding media (such as grinding balls) or clean the residual materials in the cylinder, the operator can simply open the sliding door and operate through the replacement port without disassembling the cylinder, which greatly reduces the difficulty and workload of operation and improves maintenance efficiency.
[0021] The beneficial effects of this application are: 1. The drive mechanism drives the cylinder to rotate through the meshing of the drive component, the second gear and the first gear. Compared with the belt drive which is prone to slippage and has a large power loss, the gear meshing drive can avoid the slippage problem, making the power transmission more direct and stable, effectively reducing power loss, and ensuring that the cylinder speed remains stable at all times. 2. Stable rotation speed ensures that the impact and grinding force of the grinding media on the material are uniform, thereby ensuring uniform fineness and stable output of the grinding products. This solves the problem of uneven product quality caused by speed fluctuations in belt drives. In addition, gear drives have a stronger load-bearing capacity and can be adapted to grinding operations with larger loads, overcoming the limitation of belt drives in terms of applicable scenarios. 3. By setting a protective cover outside the first gear and extending it above the second gear, the protective cover can effectively block dust and impurities in the grinding environment from entering the meshing area of the first and second gears, preventing dust from adhering to the tooth surface and affecting meshing accuracy, or impurities from entering the meshing gap and causing abnormal wear of the gears, thereby protecting the gear transmission system and extending the service life of the gears.

Detailed Implementation
[0024] The technical solutions of the embodiments of this application will be clearly described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application are within the scope of protection of this application.
[0025] The terms "first," "second," etc., used in the specification and claims of this application are used to distinguish similar objects and not to describe a specific order or sequence. It should be understood that such use of data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class and the number of objects is not limited; for example, a first object can be one or more. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.
[0026] The ball mill provided in this application will be described in detail below with reference to the accompanying drawings, through specific embodiments and application scenarios.
[0027] Example 1: like Figures 1 to 3 As shown, this application provides a ball mill, comprising: Support base 100; The cylinder 200 is mounted on the support base 100, with one end being the feed inlet 210 and the other end being the discharge outlet 220; A drive mechanism, connected to the cylinder 200 and used to drive the cylinder 200 to rotate, includes: The drive component 300 is mounted on the support base 100; The first gear 400 is disposed on the outer wall of the cylinder 200; The second gear 500 is connected to the drive assembly 300 and meshes with the first gear 400; The cylinder 200 is rotatably mounted on the support base 100 and rotates through the cooperation of the drive assembly 300, the second gear 500, and the first gear 400.
[0028] In some embodiments of this application, such as Figure 1 As shown, the ball mill described above uses a support base 100 to support the cylinder 200, ensuring that the cylinder 200 remains stable during rotation and avoiding wobbling of the cylinder 200 due to unstable support, which would affect the grinding accuracy. The cylinder 200 has a feed inlet 210 at one end and a discharge outlet 220 at the other end. The cylinder 200 contains grinding media, and the material is fully in contact with the grinding media in the cylinder 200 to achieve grinding, and is finally discharged from the storage port.
[0029] Meanwhile, the drive mechanism drives the cylinder 200 to rotate through the meshing of the drive component 300, the second gear 500, and the first gear 400. Compared with belt drives, which are prone to slippage and have high power loss, gear meshing drives can avoid slippage problems, making power transmission more direct and stable, effectively reducing power loss, and ensuring that the rotational speed of the cylinder 200 remains stable. Moreover, the stable rotational speed allows the impact of the grinding media on the material and the grinding force to be uniform, thereby ensuring uniform fineness of the grinding products and stable output. This solves the problem of uneven product quality caused by speed fluctuations in belt drives. Furthermore, gear drives have a stronger load-bearing capacity and can be adapted to grinding operations with larger loads, overcoming the limitation of belt drives in terms of applicable scenarios.
[0030] Furthermore, the cylinder 200 is also provided with a replacement port, which is equipped with a sliding door 700 and a handle 710.
[0031] By setting a replacement port on the cylinder 200, and a sliding door 700 on the replacement port with a handle 710 on the sliding door 700, the handle 710 makes it convenient for operators to open or close the sliding door 700, simplifying the operation process. When it is necessary to replace the grinding media (such as grinding balls) or clean the residual materials inside the cylinder 200, it is only necessary to open the sliding door 700 to operate through the replacement port without disassembling the cylinder 200, which greatly reduces the difficulty and workload of operation and improves maintenance efficiency.
[0032] Example 2: This application provides a ball mill, which, in addition to the above-mentioned technical features, also includes the following technical features.
[0033] like Figure 1 and Figure 2 As shown, the drive component 300 includes: The drive motor 310 is mounted on the support base 100; The regulating box 320 is mounted on the support base 100 and connected to the drive motor 310; The connecting shaft 330 has one end connected to the adjusting box 320 and the other end connected to the second gear 500; It also includes an adjustment motor 340, which is connected to the adjustment box 320 and used to adjust the gear.
[0034] In this embodiment, the aforementioned drive assembly 300 is used. The drive motor 310 provides power for the rotation of the cylinder 200. After the regulating box 320 is connected to the drive motor 310, the power is stably transmitted to the second gear 500 through the connecting shaft 330, ensuring power transmission. The structure of the connecting shaft 330, with one end connected to the regulating box 320 and the other end connected to the second gear 500, further ensures the stability of power transmission. At the same time, the regulating motor 340 is connected to the regulating box 320 and used to adjust the gear. The gear can be adjusted according to the grinding requirements of different materials (such as material hardness and differences in required grinding fineness), thereby changing the power output of the drive assembly 300 and the rotation speed of the cylinder 200. This allows the ball mill to be adapted to grinding operations of various materials, improving the versatility of the equipment.
[0035] For example, for materials with higher hardness, the motor speed can be adjusted to a higher setting (340°) to increase the cylinder speed (200°) and the impact force of the grinding media, ensuring thorough grinding. For materials with lower hardness requiring fine grinding, the setting can be lowered to reduce the speed and ensure fineness of the grinding. This solves the problem of belt drives being unable to flexibly adjust the speed and prone to fluctuations, further improving the accuracy of the grinding operation.
[0036] Furthermore: The cylinder 200 is provided with a mounting protrusion 230, and the first gear 400 is mounted on the mounting protrusion 230.
[0037] A mounting protrusion 230, which is an annular structure, is provided on the cylinder 200. The first gear 400 is mounted on the mounting protrusion 230. The mounting protrusion 230 positions the first gear 400, ensuring that it remains coaxial with the cylinder 200 during installation. This prevents misalignment of the first gear 400 during installation, which could lead to misalignment with the second gear 500 and abnormal wear caused by misaligned meshing, thus extending the gear's service life. Furthermore, the mounting protrusion 230 enhances the connection between the first gear 400 and the cylinder 200, making it less prone to loosening or displacement when the first gear 400 rotates at high speed with the cylinder 200 and bears large torques, ensuring long-term stable operation of the transmission system.
[0038] Example 3: This application provides a ball mill, which, in addition to the above-mentioned technical features, also includes the following technical features.
[0039] like Figures 1 to 3As shown, the first gear 400 includes a mounting portion 410 that engages with the mounting protrusion 230, a toothed portion 420 that meshes with the second gear 500, and a reinforcing portion 430 that connects the toothed portion 420 and the mounting portion 410. The reinforcing portion 430 is composed of a plurality of reinforcing ribs 440 evenly distributed.
[0040] In this embodiment, the first gear 400 structure, with the mounting part 410 cooperating with the mounting protrusion 230, enables the docking and installation of the first gear 400 and the cylinder 200, further enhancing the connection stability between the first gear 400 and the cylinder 200 and preventing relative slippage of the first gear 400 during operation. The toothed part 420 meshes with the second gear 500, and its tooth design ensures tightness and smoothness of meshing, reducing gaps during meshing and improving transmission efficiency. In addition, the reinforcing part 430 connecting the toothed part 420 and the mounting part 410 is composed of multiple evenly distributed reinforcing ribs 440. The evenly distributed reinforcing ribs 440 can significantly improve the overall structural strength and torque resistance of the first gear 400, making it less prone to deformation or breakage when subjected to large transmission torque, adapting to larger load grinding operations, and extending the service life of the first gear 400.
[0041] Example 4: This application provides a ball mill, which, in addition to the above-mentioned technical features, also includes the following technical features.
[0042] like Figure 1 As shown, a protective cover 600 is provided outside the first gear 400, and the protective cover 600 extends above the second gear 500 and covers the second gear 500 simultaneously.
[0043] In this embodiment, by providing a protective cover 600 outside the first gear 400 and extending the protective cover 600 to cover the second gear 500 simultaneously, the protective cover 600 can effectively block dust and impurities in the grinding environment from entering the meshing area of the first gear 400 and the second gear 500, avoiding dust adhering to the tooth surface and affecting the meshing accuracy, or impurities entering the meshing gap and causing abnormal wear of the gears, thereby protecting the gear transmission system and extending the service life of the gears.
[0044] Meanwhile, the protective cover 600 encloses both gears, preventing operators from accidentally coming into contact with the rotating gears during equipment operation, thus improving equipment safety, eliminating safety hazards, ensuring that the gears are always in good working condition, and improving grinding quality and efficiency.
