The application of jet mills is quite extensive, so today I will briefly talk about the advantages of the special jet mill equipment for battery materials in the process of use.
The grinding and classifier equipment is at the end of the process, which has a great impact on the performance of the final product. Therefore, the processing of electrode materials is an important link. Due to the high price of battery positive raw materials, if the crushed products are unqualified or over-pulverized, the yield will decrease. It will be greatly reduced, and the loss will be very large. Therefore, whether the products produced by the crushing equipment can achieve narrow particle size, no over-grinding and large particles, and the requirements of low fine powder rate are particularly important!
The crushing and grinding of electrode materials can use many crushing equipment, such as: grinder, pin-type sand mill, jet mill, etc. Among them, the jet milling equipment is second to none. The jet milling equipment has the characteristics of large production capacity, high degree of automation, fine particle size, narrow particle size distribution, high purity, high activity, and good dispersion, which fully meet the preparation requirements of electrode materials, so it is widely used. application.
1. Without heating up, the grinding of materials is carried out under the state of gas expansion, and the temperature can be controlled at a constant 10°C;
2. No pollution, the high-speed and high-pressure clean air drives the materials to collide with each other to achieve crushing, without the intervention of solid impurities, ceramics can be pasted on the contact parts of the equipment and materials according to the characteristics of the materials and application requirements, and the key components are made of ceramic materials, which can be strictly controlled iron content;
3. The wear is small. The material crushing process is completed by the collision of material particles. The whole system operates under negative pressure, and the material particles do not directly collide or rub against the equipment;
4. For materials with special properties, a closed-circuit airflow pulverization system protected by inert gas can be used;
5. PLC intelligent terminal control is adopted to control the crushing process, which can ensure the stability of the finished particle size
