Abstract

Technical Field
[0001] This utility model relates to the field of ore processing technology, and in particular to a device for evaluating the steady-state operation of grinding processes. Background Technology
[0002] Ball mills are commonly used in the processing of ores. They are a common type of ore crushing equipment used to refine ore particles into smaller powders for subsequent beneficiation, flotation, and refining processes. Therefore, ball mills play an important role in the production and processing of ores.
[0003] During ball mill operation, the ore material inside the mill cylinder undergoes compression and friction, generating a large amount of heat and causing the internal temperature of the cylinder to rise. Temperature monitoring is necessary for achieving steady-state assessment of the ball mill's operation. Currently, most methods rely on manual, timed measurements, which are inefficient and suffer from significant lag. Although temperature monitoring devices for ball mills are available on the market, most of these devices have temperature sensors installed on the outer wall of the mill. The heat transfer process through the sidewall generates substantial energy consumption, easily leading to inaccurate steady-state assessments.
[0004] Therefore, it is necessary to propose a steady-state evaluation device for grinding process operation to solve the above problems. Utility Model Content

Although there are temperature monitoring devices for ball mills on the market, the temperature sensors in most of these devices are installed on the outer wall of the ball mill. The heat transfer process through the side wall of the ball mill generates a lot of energy consumption, which can easily lead to inaccurate steady-state evaluation.

[0023] This utility model provides, for example Figures 1-6 The grinding process steady-state evaluation device shown includes a base 1, with two fixed sleeves 3 positioned above the base 1. A rotating cylinder 2 is positioned between the two fixed sleeves 3 and is rotatably connected to the fixed sleeves 3. A rotating pipe 4 is fixedly connected to the side of the fixed sleeve 3 facing away from the rotating cylinder 2, and a support 5 is rotatably connected to the rotating pipe 4. The support 5 is fixedly connected to the base 1. The rotating cylinder 2 rotates between the two fixed sleeves 3, and grinding media (not shown in the figure) are installed inside the rotating cylinder 2 to crush the ore.
[0024] In practical use, a ball bearing can be installed between the rotating drum 2 and the fixed sleeve 3 to reduce wear. A material feeding groove and a cover plate can be installed on the rotating drum 2. The material can be loaded and unloaded by opening the cover plate through the material feeding groove.
[0025] A square base 16 is fixedly connected to the top of the base 1, and a gear 17 is rotatably connected to the square base 16. A gear ring 15 is fixedly connected to the outside of the rotating cylinder 2, and the gear ring 15 meshes with the gear 17. A drive mechanism 18 is provided on the square base 16, and the drive mechanism 18 cooperates with the gear 17. The drive mechanism 18 includes a motor, a reducer, and other structures, and is used to drive the gear 17 to rotate. Since the gear ring 15 meshes with the gear 17, the gear ring 15 drives the rotating cylinder 2 to rotate between the two fixed sleeves 3.
[0026] The rotating drum 2, fixed sleeve 3, drive mechanism 18, etc. form a ball mill for ore crushing and processing.
[0027] A horizontal plate 6 is provided inside the rotating drum 2. The horizontal plate 6 is located at the top inside the rotating drum 2, and its two ends are fixedly connected to two fixed sleeves 3 respectively. Multiple installation chambers 7 are evenly distributed inside the horizontal plate 6. Temperature sensors 8 are fixedly installed inside the installation chambers 7 to monitor the temperature inside the rotating drum 2.
[0028] By setting up structures such as the horizontal plate 6 and the installation chamber 7, the temperature sensor 8 extends into the inner cavity of the rotating drum 2 to monitor the temperature of the ball mill equipment within the inner cavity of the rotating drum 2, thereby improving the accuracy of temperature detection and ensuring steady-state evaluation of the grinding process operation.
[0029] During the crushing process, the ore and grinding media are mostly located in the lower half of the drum 2, so they will not collide with the temperature sensor 8, and the horizontal plate 6 can provide protection.
[0030] The lower surface of the horizontal plate 6 has multiple grooves 9, each corresponding to a different mounting chamber 7. A heat-conducting plate 10 is fixedly connected inside each groove 9, and the heat-conducting plate 10 cooperates with a corresponding temperature sensor 8. The heat-conducting plate 10 can be made of, but is not limited to, polycrystalline diamond ceramic material, which has good thermal conductivity and high strength. The heat-conducting plate 10 ensures heat transfer, improves temperature monitoring efficiency, and protects the temperature sensor 8.
[0031] Considering that some debris will adhere to the inner wall of the rotating drum 2 during the crushing process, a scraper 11 for scraping the inner wall of the rotating drum 2 is provided on the horizontal plate 6 to achieve the scraping treatment of the debris. The two ends of the side wall of the horizontal plate 6 are fixedly connected to the fixing blocks 12, and the two fixing blocks 12 are fixedly connected to the rotating shaft 13. The scraper 11 is rotatably connected to the rotating shaft 13. The two ends of the rotating shaft 13 are fitted with torsion springs 14. One end of the torsion spring 14 is fixedly connected to the scraper 11, and the other end of the torsion spring 14 is fixedly connected to the rotating shaft 13.
[0032] During the rotation of the drum 2, the scraper 11 pushes and scrapes the debris adhering to the inner wall of the drum 2, improving the efficiency of the crushing process and facilitating the subsequent cleaning of the drum 2. At the same time, the elastic support force of the torsion spring 14 ensures that the scraper 11 always adheres to the inner wall of the drum 2.
