Description

Technical Field

[0001] This utility model relates to the field of calcium carbonate powder grinding, specifically a fine grinding device for calcium carbonate powder. Background Technology

[0002] Calcium carbonate is widely used in numerous industries, including papermaking, plastics, rubber, coatings, inks, daily chemicals, food, and pharmaceuticals. With the development of these industries, the requirements for the fineness, purity, and whiteness of calcium carbonate products are constantly increasing. In some high-end applications, such as electronic materials and optical materials, not only is ultra-fine particle size required, but specific functional properties such as high dispersibility and good compatibility are also necessary. Calcium carbonate is one of the most common substances on Earth, with abundant and widely distributed raw materials such as calcite, marble, and limestone, providing a sufficient raw material base for fine grinding. Fine grinding technology can increase the added value of calcium carbonate products, meeting market demands while bringing higher economic benefits to enterprises.

[0003] Difficult-to-replace grinding discs in grinding equipment can lead to reduced production efficiency. Replacing grinding discs should be a quick and routine operation, but if difficult, it can consume significant time, extending equipment downtime and slowing down overall production. Difficult-to-replace grinding discs may cause frequent equipment failures due to improper installation or disassembly, further reducing effective equipment uptime and impacting production efficiency. During replacement, the difficulty of the operation may damage the grinding disc and other mating components, such as bearings and motor shafts, increasing maintenance costs and replacement expenses. If worn grinding discs are not replaced promptly after long-term use, grinding precision will decrease, resulting in uneven particle size distribution in the product, failing to meet precision requirements. Delayed grinding disc replacement or disruption of the equipment's normal operation during replacement can cause significant quality differences between batches, reducing product consistency and stability. Operators may be injured during grinding disc replacement due to the application of significant external force or improper handling methods, such as crushing injuries or sprains. Improperly installed grinding discs may loosen or fall off during operation, causing severe equipment vibration and even damage, posing a significant safety hazard. Utility Model Content

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figure 1-6 This utility model provides a technical solution: a fine grinding device for calcium carbonate powder, including a motor chamber 3, a motor 24 fixedly connected inside the motor chamber 3, a tenon 6 fixedly connected to the output end of the motor 24, a grinding chamber 7 fixedly connected above the motor chamber 3, three grinding plates 4 fixedly connected inside the grinding chamber 7, grinding discs 5 of different sizes movably connected to the inside of the grinding plates 4, a tenon 6 fixedly connected to the upper center of the grinding disc 5, a base column 20 fixedly connected to the lower center of the grinding disc 5, a tenon groove 21 provided in the base column 20, the tenon 6 and the tenon groove 21 being tenon-mortise and tenon-tenon connected, a chamber door 15 provided on the side of the grinding chamber 7, the chamber door 15 being rotatably connected to the grinding chamber 7, and a handle 16 fixedly connected to the chamber door 15. The design for easy replacement of grinding discs allows for rapid replacement, greatly reducing equipment downtime, increasing effective operating time, and thus improving overall production efficiency. Different production processes may require different models or specifications of grinding discs. The easily replaceable grinding discs allow operators to quickly adjust to actual needs without spending a lot of time changing parts, making the production process smoother and more efficient.

[0027] A storage bin 2 is fixedly connected to the lower end of the motor compartment 3. A second door 18 is provided on the side of the storage bin 2, and the second door 18 is rotatably connected to the storage bin 2. A second handle 19 is fixedly connected to the second door 18. A base 1 is fixedly connected to the lower end of the storage bin 2. A support frame 17 is fixedly connected to the four ends of the base 1. A support column 14 is installed on one side of the base 1. A support plate 13 is fixedly connected above the support column 14. A housing 9 is fixedly connected to the support plate 13. A motor 11 and a second motor 12 are fixedly connected to the side of the housing 9. The housing 9 has an opening... A feed inlet guard plate 10 is fixedly connected to the top of the housing 9. Grinding wheels 22 are fixedly connected inside the housing 9 to the output ends of motors 11 and 2. Both motors 11 and 2 rotate in opposite directions. Several grinding teeth 23 are fixedly connected to the grinding wheels 22. A guide pipe 8 is connected through the side of the housing 9 near the grinding chamber 7, and the other end of the guide pipe 8 is connected through the side of the grinding chamber 7. Large pieces of calcium carbonate raw material have a relatively small surface area, resulting in limited contact area between the grinding media and the raw material during fine grinding, leading to low grinding efficiency. However, by pre-crushing them into smaller particles, the total surface area of ​​the particles increases significantly, allowing the grinding media to contact the raw material more fully, thereby significantly improving grinding efficiency. Large pieces of raw material are not easily dispersed evenly in the grinding equipment, easily causing uneven grinding and localized overload of the equipment. The crushed small particles can be more evenly distributed in the grinding device, making the grinding process more stable and efficient, reducing grinding resistance caused by raw material agglomeration or accumulation, and lowering the energy consumption of the equipment.

[0028] Working principle: When it is necessary to replace the grinding disc 5, simply open the door 15. Because the grinding discs 5 are connected by tenons 6 and tenons 21 in the base column 20, and the output end of the motor 24 is also fixedly connected to tenons 6, the grinding disc 5 can be removed and replaced simply by lifting the tenons 6 fixedly connected to the grinding disc 4. The easy replacement of the grinding disc allows operators to quickly adjust according to actual needs, without spending a lot of time on replacing parts, making the production process smoother and more efficient.

[0029] When fine grinding of calcium carbonate raw materials is required, the first step is to put the raw materials into the feed inlet, start motor 11 and motor 22 to drive the grinding wheel 22 to rotate. The two grinding wheels 22 rotate relative to each other, and the crushed raw materials are sent to the grinding chamber 7 through the feed pipe 8. Start motor 3 to drive the grinding disc 5 to rotate. The grinding disc 5 and the grinding plate 4 cooperate to achieve the effect of grinding calcium carbonate powder. The gap between the grinding disc 5 and the grinding plate 4 gradually decreases from top to bottom, thus gradually refining the calcium carbonate powder. The well ground calcium carbonate powder falls into the storage silo 2. The overall structure is convenient and efficient.

[0030] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
