Abstract
Description
Technical Field
[0001] This application relates to the field of grinding mill technology, specifically a grinding mill for the production of ultrafine heavy calcium carbonate. Background Technology
[0002] Grinding mills are an indispensable piece of equipment in the production process of ultrafine heavy calcium carbonate. The performance of grinding mills directly affects the product quality of ultrafine heavy calcium carbonate. At present, commonly used grinding mills generally use grinding rings and grinding rollers to grind calcium carbonate into powder.
[0003] Currently, in the process of using traditional grinding mills, the grinding ring and grinding roller work together to grind, relying on the crushing action in one direction. This can easily lead to local over-grinding or corner areas, so a fan is used to discharge the material upwards, and the material needs to be separated, with larger pieces being put back into the grinding mill, thus reducing grinding efficiency. Utility Model Content

Therefore, it is necessary to use a fan to discharge the material upwards and separate the material, and put larger materials back into the grinding, thereby reducing the grinding efficiency.
[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This application provides a grinding mill for producing ultrafine heavy calcium carbonate, including a grinding cylinder.

The multiple sets of side toothed columns are respectively meshed with the central toothed column. A filter ring is fixedly installed on the outer ring wall of the circular disk.

With the filter ring rotating with the circular disk, qualified fine powder can be screened and discharged in real time, improving grinding efficiency and product particle size uniformity, and ensuring the high-quality production of ultrafine heavy calcium carbonate.
[0007] Optionally, a feed hole is provided on the upper side of the cylinder cover, and a feed pipe is welded to the upper end of the cylinder cover above the feed hole.

[0014] By adopting the above technical solution, the L-shaped discharge pipe can fix the blower, while the blower can exert negative pressure on the L-shaped discharge pipe to discharge materials, thereby increasing the negative pressure below the grinding cylinder, enhancing the material discharge effect, and reducing the risk of filter ring clogging.
[0015] Optionally, the drive mechanism includes a drive motor mounted on the upper end of the cylinder cover, and the output shaft of the drive motor is fixedly mounted to the central gear column.
[0016] By adopting the above technical solution, the cylinder cover can fix the drive motor, and the drive motor can drive the central gear column to rotate.
[0017] Compared with the prior art, the beneficial effects of the technical solution of this application are as follows: The technical solution of this application uses the rotation of the central toothed column to drive the circular disk and multiple sets of side toothed columns to revolve. At the same time, the side toothed columns mesh with the racks on the inner wall of the grinding cylinder and the central toothed column to achieve rotation, forming a multi-directional, high-frequency shearing and grinding force field. This effectively avoids the problem of local over-grinding or grinding dead angles caused by the single-direction crushing of traditional grinding rollers and grinding rings.

At the same time, the side toothed columns 4 mesh with the rack 5 on the inner wall of the grinding cylinder 1 and the central toothed column 3 to achieve rotation, forming a multi-directional, high-frequency shearing and grinding force field. This effectively avoids the problem of local over-grinding or grinding dead angle caused by the single-direction crushing of traditional grinding rollers and grinding rings. With the filter ring 7 rotating with the circular disk 6, qualified fine powder can be screened and discharged in real time, improving grinding efficiency and product particle size uniformity, and ensuring the high-quality production of ultrafine heavy calcium carbonate.
[0022] In the technical solution of this application, such as Figure 1 and Figure 2 As shown, the drive mechanism includes a drive motor 8 mounted on the upper end of the cylinder cover 2. The output shaft of the drive motor 8 is fixedly mounted to the central gear column 3. The cylinder cover 2 can fix the drive motor 8, and the drive motor 8 can drive the central gear column 3 to rotate.
[0023] In the technical solution of this application, such as Figure 1 and Figure 2 As shown, a feed hole 9 is provided on the upper side of the cylinder cover 2. A feed pipe 10 is welded to the upper end of the cylinder cover 2 above the feed hole 9. The cylinder cover 2 can fix the feed pipe 10, and the feed pipe 10 can be connected to an external feed pipe. Thus, the feed pipe 10 and the feed hole 9 work together to convey materials. An L-shaped discharge pipe 12 is fixedly installed at the lower end of the grinding cylinder 1. The grinding cylinder 1 can fix the L-shaped discharge pipe 12, and the L-shaped discharge pipe 12 can discharge materials. A fan 13 is fixedly installed on the outer wall of the bend of the L-shaped discharge pipe 12. The L-shaped discharge pipe 12 can fix the fan 13, and the fan 13 can create negative pressure discharge through the L-shaped discharge pipe 12, thereby increasing the negative pressure below the grinding cylinder 1, enhancing the material discharge effect, and reducing the risk of filter ring 7 clogging.
[0024] In the technical solution of this application, such as Figure 1 and Figure 2 As shown, multiple sets of support legs 11 are fixedly installed on the outer wall of the conical surface below the grinding cylinder 1. The grinding cylinder 1 can fix the support legs 11, and the support legs 11 can support the grinding cylinder 1.
[0025] During use, the operator connects the external feed pipe to the feed pipe 10, allowing calcium carbonate material to enter the grinding cylinder 1 through the feed pipe 10 and feed hole 9. The drive motor 8 drives the central toothed column 3 to rotate, which in turn drives the circular disk 6 and multiple sets of side toothed columns 4 to revolve. Simultaneously, the side toothed columns 4 mesh with the racks 5 on the inner wall of the grinding cylinder 1 to achieve rotation, forming a multi-directional high-frequency shearing grinding force field to fully grind the material. During the grinding process, the filter ring 7 is swung by the centrifugal force of the rotating circular disk 6, and the fine powder that has been properly ground can then be discharged from the filter ring 7. After falling to the bottom of the grinding cylinder 1, the fine powder is sucked out by the negative pressure generated by the fan 13 of the L-shaped discharge pipe 12. The filter ring 7 and the circular disk 6, as if... Figure 4 The device has a certain height difference, which is the height of the fine powder. Larger particles will be higher than this height difference. The larger calcium carbonate particles that are missed will be ground into powder when the toothed rack 5, side toothed column 4 and central toothed column 3 rotate. The whole process achieves continuous grinding, screening and discharge through mechanical linkage, which improves the uniformity of product particle size and production efficiency. In addition, the grinding cylinder 1 can be separated from the cylinder cover 2, which makes it convenient for the staff to maintain the inside of the grinding cylinder 1 and replace the filter ring 7.
