Description

Technical Field

[0001] This utility model relates to the field of ball mill technology, and in particular to a grinding media adding device for ball mills. Background Technology

[0002] In material processing in industries such as mining, building materials, and chemicals, ball mills, as core grinding equipment, rely on internal grinding media to crush block or granular materials to a specified fineness through impact and grinding. With the expansion of production scale and the increase in processing precision requirements, the demand for accurate proportioning and timely addition of grinding media in ball mills is becoming increasingly prominent. Improper proportioning can easily lead to a decrease in grinding efficiency or failure to meet material fineness standards. At the same time, grinding media will be worn down and consumed during long-term use, requiring regular replenishment. Therefore, grinding media adding devices have become key auxiliary equipment to ensure the continuous and stable operation of ball mills, and their performance directly affects the processing efficiency and product quality of ball mills.

[0003] The core structure of existing grinding media adding devices for ball mills typically includes a storage silo, a conveying pump, a conveyor belt, and manual valves. The storage silo is usually a single-chamber design used to store grinding media of a single specification or mixed grinding media. The pneumatic conveying pump uses compressed air to transport the grinding media from the storage silo to the ball mill inlet. The inclined conveyor belt is driven by a motor to lift the grinding media from the ground to the ball mill inlet. The addition amount is mostly controlled by manual valves. Operators manually adjust the valve opening to control the addition amount by observing the remaining amount of grinding media in the ball mill.

[0004] Existing grinding media adding devices are prone to grinding media jamming during actual operation, affecting the smoothness of the adding process. The connection between the discharge port of the storage hopper and the conveying pipe of existing devices is mostly a right-angle diameter change design. When the grinding media passes through, some steel balls are easily squeezed and stuck together at the connection. For example, a larger diameter steel ball gets stuck at the diameter change, making it difficult for subsequent steel balls to pass smoothly, forming a blockage. If an inclined conveyor belt is used, if the conveyor belt surface does not have an anti-slip or guiding structure, some steel balls are prone to rolling off to the edge of the conveyor belt during the conveying process. After colliding with the baffles on both sides of the conveyor belt, they get stuck in the gap between the baffles and the conveyor belt, causing the conveyor belt to jam or even stop. Therefore, a grinding media adding device for ball mills is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a grinding media adding device for ball mills, which aims to improve the problem that existing grinding media adding devices are prone to grinding media jamming during actual operation, affecting the smoothness of the adding process.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a grinding media adding device for a ball mill, which is suitable for adding grinding media to a ball mill, comprising: The ground, used to support the device; The ball storage bin, located underground, is used to store steel balls of different sizes; The ball mill body is located above the ground and uses steel balls to grind materials. A magnetic clamp, installed above the ball storage bin, is used to attract steel balls and release them at a designated location; Electric slide rail 1, installed above the ground, is used to drive the gantry frame to slide horizontally; The gantry frame, located above the ball storage bin, is used to install electric slide rail two and electric slide rail three; The electric slide rail 2 includes a drive motor, and a pulley is fixedly connected to the output end of the drive motor. The pulley is in contact with the slide rail body. The outer wall of the slide rail body is fixedly connected to the outer wall of the gantry frame. A connecting plate is slidably connected to the outer wall of the slide rail body.

[0007] Furthermore, the electric slide rail is installed below the gantry frame, and the gantry frame is installed above the ground.

[0008] Furthermore, the electric slide rail two and electric slide rail three are installed on the outer wall of the gantry frame, and the magnetic clamp is installed below the gantry frame.

[0009] Furthermore, a horizontal conveying mechanism is provided on one side of the outer wall of the ball storage bin, and a lifting conveying mechanism is provided at one end of the horizontal conveying mechanism.

[0010] Furthermore, the lifting and conveying mechanism is located above the ground, and a conveying and distributing mechanism is provided on one side of the outer wall of the lifting and conveying mechanism.

[0011] Furthermore, the conveying and distributing mechanism is located on one side of the outer wall of the ball mill body, and the conveying and distributing mechanism is used to convey and distribute steel balls into multiple ball mill bodies.

[0012] Furthermore, the lifting and conveying mechanism is used to convey the steel balls to a height adapted to the conveying and distributing mechanism.

[0013] Furthermore, the horizontal conveying mechanism is used to convey steel balls to the loading port of the lifting conveying mechanism.

[0014] This utility model has the following beneficial effects: In this invention, a precise ball distribution and gripping structure is formed by a multi-divided ball storage bin, an electric slide rail one, a gantry frame, and an electric slide rail two. The multiple compartments of the ball storage bin can store steel balls of different specifications to achieve the basic ball distribution. The electric slide rail one drives the gantry frame to move horizontally to the target steel ball division area. The electric slide rail three drives the magnetic clamp to lift and lower vertically to attract the steel balls. The electric slide rail two then drives the magnetic clamp to move horizontally to the top of the conveying mechanism. Through the synergistic effect of this structure, the effect of accurately gripping steel balls of different specifications without manual sorting is achieved. This not only meets the processing requirements of the ball mill body for steel balls with different ratios, but also avoids the problems of specification confusion and low efficiency when manually distributing balls, thus improving the accuracy of ball distribution and the degree of automation of gripping.

[0015] In this invention, a multi-equipment ball supply and conveying structure is constructed by a horizontal conveying mechanism, a lifting conveying mechanism, and a conveying and distributing mechanism. The horizontal conveying mechanism receives the steel balls released by the magnetic clamp and conveys them to the lifting conveying mechanism. The lifting conveying mechanism lifts the steel balls to a designated height and then transfers them to the conveying and distributing mechanism. The conveying and distributing mechanism then distributes the steel balls to multiple ball mill bodies. Through the coordinated operation of this structure, the effect of automatically adding steel balls to multiple ball mill bodies simultaneously without the need for manual ball supply is achieved. This significantly reduces the amount of manual ball supply work between multiple ball mills, avoids the problems of untimely or uneven ball supply during manual ball supply, and improves the overall operating efficiency and ball supply stability of multiple ball mills.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Reference Figures 1-5 This utility model provides an embodiment of a grinding media adding device for a ball mill. The device is suitable for adding grinding media to a ball mill and includes: a ground 1 for supporting the device; a ball storage chamber 2, located inside the ground 1, for storing steel balls of different specifications; the ball storage chamber 2 has multiple partitioned areas that can hold steel balls of different specifications respectively, and the steel balls are classified and stored through physical separation to avoid mixing of steel balls of different specifications, thus providing a basis for subsequent accurate ball mixing; The ball mill body 6 is set above the ground 1 and uses steel balls to grind materials. The ball mill body 6 uses the impact and grinding action of the steel balls inside to crush or grind the materials. The magnetic clamp 10 is set above the ball storage bin 2 and is used to attract steel balls and release them at a designated position. The electric slide rail 3 is set above the ground 1 and is used to drive the gantry 8 to slide in the horizontal direction. The gantry frame 8, located above the ball storage bin 2, is used to install electric slide rail 2 9 and electric slide rail 3 11. Electric slide rail 2 9 includes a drive motor 901, and a pulley 902 is fixedly connected to the output end of the drive motor 901. The drive motor 901 drives the pulley 902 to rotate, so that the electric slide rail 2 9 drives the magnetic clamp 10 to slide horizontally. The pulley 902 is in contact with the slide rail body 903. The outer wall of the slide rail body 903 is fixedly connected to the outer wall of the gantry frame 8. A connecting plate 904 is slidably connected to the outer wall of the slide rail body 903. Electric slide rail 3 is located below the gantry frame 8, which is located above the ground 1. Electric slide rail 3 provides the gantry frame 8 with a horizontal moving track and power, which can drive the gantry frame 8 to slide horizontally in a preset direction, so that the gantry frame 8 and the magnetic clamp 10 on it can be accurately moved to the top of different partitioned areas in the ball storage bin 2 to achieve the gripping and positioning of steel balls of different sizes.

[0020] Specifically, the ground 1 supports all components of the entire device. The ball storage chamber 2 stores steel balls of different specifications in multiple internal compartments to prevent mixing and provides a basis for precise ball distribution. The ball mill body 6 receives the steel balls and uses the impact and grinding action of the steel balls to crush or grind the materials. The magnetic clamp 10 adsorbs the steel balls in the ball storage chamber 2 and releases them at a designated position. The electric slide rail 3 provides a horizontal moving track and power for the gantry 8, driving the gantry 8 and the magnetic clamp 10 to move precisely above different compartments of the ball storage chamber 2, realizing the gripping and positioning of steel balls of different specifications. With the help of the magnetic clamp 10, the steel balls are precisely gripped to meet the ball distribution requirements.

[0021] Reference Figures 1-5 Electric slide rail 2 9 and electric slide rail 3 11 are installed on the outer wall of the gantry frame 8. Electric slide rail 2 9 can drive the magnetic clamp 10 to slide horizontally along the gantry frame 8, so that the magnetic clamp 10 after adsorbing the steel ball can move accurately from above the ball storage bin 2 to above the horizontal conveying mechanism 7, realizing the horizontal transfer of the steel ball from the gripping position to the conveying position. Electric slide rail 3 11 can drive the magnetic clamp 10 to rise and fall vertically. When it falls, the magnetic clamp 10 is brought close to the steel ball in the ball storage bin 2 to complete the adsorption. After adsorption, it rises and resets to avoid collision of the steel ball during the transfer process. A magnetic clamp 10 is installed below the gantry frame 8. A horizontal conveying mechanism 7 is installed on one side of the outer wall of the ball storage bin 2. A lifting conveying mechanism 4 is installed at one end of the horizontal conveying mechanism 7 to receive the steel balls released by the magnetic clamp 10. The lifting conveying mechanism 4 is installed above the ground 1. A conveying and distributing mechanism 5 is installed on one side of the outer wall of the lifting conveying mechanism 4. The conveying and distributing mechanism 5 is installed on one side of the outer wall of the ball mill body 6. The conveying and distributing mechanism 5 is used to convey and distribute the steel balls into multiple ball mill bodies 6. The conveying and distributing mechanism 5 receives the steel balls transferred by the lifting conveying mechanism 4 and distributes the steel balls into multiple ball mill bodies 6 through its own structure, avoiding the steel balls being concentrated in a single ball mill and realizing the synchronous ball supply to multiple ball mill bodies 6. The lifting conveying mechanism 4 is used to convey the steel balls to a height that is compatible with the conveying and distributing mechanism 5. The lifting conveyor 4 receives the steel balls conveyed by the horizontal conveyor 7. Through its own lifting structure, it raises the steel balls from a lower horizontal conveying height to a height that matches the conveying and distributing mechanism 5. Then, it transfers the steel balls to the conveying and distributing mechanism 5 through the discharge port, realizing the vertical displacement of the steel balls. The horizontal conveyor 7 is used to convey the steel balls to the loading port of the lifting conveyor 4. The horizontal conveyor 7 uses its own conveying structure to horizontally convey the steel balls from the release position of the magnetic clamp 10 to the loading port of the lifting conveyor 4, realizing the horizontal transfer of the steel balls. It connects the steel ball grabbing link and the lifting link, ensuring the continuity of the steel ball conveying process.

[0022] Specifically, the electric slide rail 2 9 on the gantry 8 drives the magnetic clamp 10 to slide horizontally along the gantry 8, transferring the adsorbed steel balls from above the ball storage bin 2 to above the horizontal conveying mechanism 7. The electric slide rail 3 11 drives the magnetic clamp 10 to rise and fall vertically. When it falls, it is easy for the magnetic clamp 10 to approach the steel ball for adsorption. When it rises and resets, it avoids collision of the steel balls during the transfer. The horizontal conveying mechanism 7, through its own conveying structure, horizontally conveys the steel balls released by the magnetic clamp 10 to the feeding port of the lifting conveying mechanism 4, connecting the steel ball grabbing and lifting links. The lifting conveying mechanism 4, through its own lifting structure, lifts the steel balls conveyed by the horizontal conveying mechanism 7 from a low height to a height that matches the conveying and distributing mechanism 5, and transfers them to the conveying and distributing mechanism 5. The conveying and distributing mechanism 5 receives the steel balls from the lifting conveying mechanism 4 and distributes the steel balls to multiple ball mill bodies 6 through its own structure, realizing synchronous ball supply for multiple ball mill bodies 6, avoiding concentrated steel ball conveying, and ensuring uniform ball supply.

[0023] Working principle: When it is necessary to add balls to the ball mill body 6, the steel balls are first poured into the ball storage bin 2 by a truck. The ball storage bin 2 has multiple partitioned areas, and different sizes of steel balls are placed in different partitions to meet the ball distribution requirements. Then, the electric slide rail 1 3 drives the gantry 8 to slide horizontally. After the gantry 8 moves to the target position, the electric slide rail 3 11 above it drives the magnetic clamp 10 to descend vertically, so that the magnetic clamp 10 attracts the steel balls in the ball storage bin 2. After the steel ball is attracted, the electric slide rail 3 11 first drives the magnetic clamp 10 to rise vertically and reset. After the vertical reset, the electric slide rail 2 9 on the gantry 8 starts to work. The drive motor 901 inside the electric slide rail 2 9 starts and drives the pulley 902 to rotate. Since the pulley 902 is in close contact with the slide rail body 903, under the rotation of the pulley 902, the electric slide rail 2 9 drives the magnetic clamp 10 to slide horizontally until the magnetic clamp 10 moves precisely to the top of the horizontal conveying mechanism 7. At this time, the magnetic clamp 10 releases the steel ball, and the steel ball falls onto the horizontal conveying mechanism 7. The horizontal conveying mechanism 7 then transports the steel ball to the loading port of the lifting conveying mechanism 4. Finally, the lifting conveyor 4 transports the steel balls to its own discharge port and transfers them to the conveying and distributing mechanism 5. The conveying and distributing mechanism 5 distributes the steel balls into multiple ball mill bodies 6, thus realizing the operation of automatically adding steel balls to multiple ball mill bodies 6.
