Description

Technical Field

[0001] This utility model relates to the field of kaolin production technology, specifically to a ball mill for kaolin production. Background Technology

[0002] Kaolin is a clay or clay rock mainly composed of kaolinite group clay minerals. Its color is mostly white, but it often appears light yellow, light green, or brownish-red due to impurities. It has good plasticity, fire resistance, and insulation properties. It is mainly formed by feldspar rocks through long-term weathering and geological processes. Kaolin is widely used in industries such as papermaking, ceramics, rubber, plastics, and coatings. It is a very important non-metallic mineral resource and plays an indispensable role in the development of modern industry.

[0003] In the processing and production of kaolin, the ball mill is one of the key pieces of equipment. The ball mill uses the rotation of the cylinder to drive the grinding media to impact and grind the kaolin, refining its particle size. Currently, when using a ball mill to grind kaolin, intense collisions and friction occur between the grinding media (such as steel balls) and the material, as well as among the grinding media themselves. This mechanical action converts mechanical energy into heat energy, raising the temperature of the material and the grinding media. This increases the internal temperature of the ball mill cylinder, which alters the viscosity of the material, potentially reducing its flowability. It also reduces the hardness of the grinding media (such as steel balls), making them more prone to wear during collisions and friction with the material and the cylinder, shortening the service life of the grinding media and increasing production costs. Utility Model Content

Detailed Implementation

[0022] 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.

[0023] Please see Figure 1-4 This utility model provides a new technical solution: a ball mill for kaolin production, including a ball mill mounting frame 1, a cylinder 2 mounted on the upper end of the ball mill mounting frame 1, a feeding device 3 rotatably mounted on the front end of the cylinder 2, the feeding device 3 being fixedly mounted on the front end of the ball mill mounting frame 1, and a discharge device 4 rotatably mounted on the rear end of the ball mill mounting frame 1, the discharge device 4 being fixedly mounted on the rear end of the ball mill mounting frame 1;

[0024] The cooling mechanism is mounted on the ball mill mounting frame 1. The cooling mechanism includes a sleeve plate 5 and a connecting box 6. The sleeve plate 5 is fixedly installed on the upper surface of the ball mill mounting frame 1 and rotates in contact with the outer surface of the cylinder 2. A cooling water tank 7 is provided inside the sleeve plate 5. The connecting box 6 is fixedly installed on the upper surface of the sleeve plate 5 and communicates with the interior of the cooling water tank 7. A first water pumping pipe 8 is fixedly installed on the lower inner left end of the sleeve plate 5. A cooling water tank 9 is placed on the left side of the ball mill mounting frame 1, and the left end of the first water pumping pipe 8 extends into the interior of the cooling water tank 9.

[0025] Furthermore, the cooling mechanism also includes a water pump 10 and two water supply pipes 11. The water pump 10 is fixedly installed on the upper surface of the cooling water tank 9. The two water supply pipes 11 are respectively fixedly installed on the water pump 10's suction end and outlet end. The end of the water supply pipe 11 installed on the water pump 10's suction end, away from the water pump 10, extends into the interior of the cooling water tank 9. A connecting pipe 12 is fixedly installed on the upper surface of the connecting box 6. The lower end of the connecting pipe 12 extends into the interior of the connecting box 6. The end of the water supply pipe 11 installed on the water pump 10's outlet end, away from the water pump 10, is connected to the upper end of the connecting pipe 12.

[0026] Furthermore, through the setting of the cooling mechanism, the first water pumping pipe 8 can directly draw water from the right end of the cooling water tank 7, thereby providing more effective cooling for the ball mill. Continuous and effective cooling can prevent the grinding media such as steel balls inside the ball mill cylinder 2 from deforming or being damaged due to overheating, thus extending the service life of the grinding media and improving the efficiency of the ball mill.

[0027] Furthermore, two mounting holes 13 are provided on the upper surface of the cooling water tank 9, and a cooling fan 14 is fixedly installed inside each of the two mounting holes 13.

[0028] Furthermore, both ends of the first water pumping pipe 8 are provided with water pumping holes 15.

[0029] Furthermore, a second water pumping pipe 16 is fixedly installed on the left end of the sleeve plate 5. The left end of the second water pumping pipe 16 extends into the interior of the cooling water tank 9, and the right end of the second water pumping pipe 16 extends into the interior of the cooling water trough 7.

[0030] Furthermore, a water outlet pipe 17 is fixedly installed on the left end of the cooling water tank 9, and the right end of the water outlet pipe 17 extends into the interior of the cooling water tank 9.

[0031] Furthermore, when using this ball mill, ensure that there is sufficient cooling water in the cooling water tank 9. Then, start the water pump 10. The water supply pipe 11 installed on the water pump 10's suction end draws out the cooling water from the cooling water tank 9. The water supply pipe 11 installed on the water pump 10's outlet end is connected to the upper end of the connecting pipe 12. The lower end of the connecting pipe 12 extends into the interior of the connecting box 6, which in turn is connected to the interior of the cooling water tank 7. In this way, the drawn-out cooling water enters the connecting box 6 through the water supply pipe 11 and the connecting pipe 12, and then flows into the cooling water tank 7, beginning to circulate between the cooling water tank 7 and the cooling water tank 9. When the ball mill is working, the cylinder 2 rotates at high speed, interacting with the kaolin and grinding media to generate a large amount of heat. The cooling water circulating inside the sleeve 5 can absorb the heat emitted by the cylinder 2, reducing the temperature of the cylinder 2. Because the sleeve 5 rotates in contact with the outer surface of the cylinder 2, the cooling water can evenly absorb heat from multiple parts of the cylinder 2. The right end of the first water pumping pipe 8 is located at the right end of the cooling water tank 7, allowing the first water pumping pipe 8 to directly pump water from the right end of the cooling water tank 7, improving the circulation efficiency of the cooling water. After absorbing heat, the cooling water flows back to the cooling water tank 9 through the second water pumping pipe 16 and the first water pumping pipe 8, where it exchanges heat with the hot water. The cooling fan 14 on the cooling water tank 9 starts, accelerating the airflow inside the cooling water tank 9 and carrying away the heat from the hot water, thus cooling the water.
