Production process: 1. Feed and mix (sanding and grinding); 2. Primary granulation (spray drying); 3. Primary crushing (airflow crushing/mechanical grinding); 4. The agglomerates form again after the secondary granulation (calcination); 5. Secondary crushing (airflow crushing); 6. Finished packaging.

In the fourth process, water removal will be carried out at the same time, and the subsequent process is airflow grinding; So the requirements for the fifth step are very high. The air flow pulverizer is required to have strong adaptability, including particle size control and moisture control, etc.

The grain size fluctuation may be due to the batch fluctuation formed by different calcination temperatures, and the front-end raw materials are also an important factor. However, if the airflow crushing function runs steadily, it will make the batches of products tend to be the same.

Through many years of on-site engineering experience, we found that sintering temperature has a great impact on the finished product, productivity and sand mill media are closely related, so in the airflow crushing on the effective targeted improvement.

Take lithium iron phosphate as an example, the reason why it is not easy to crush is due to its own characteristics. The uniformity of the particle size of the finished product, the characteristics of water absorption, the variability of the front-end process, including the solvent of the front-end ingredients and so on, will add complex factors to the subsequent grinding process.

SAC Powder has conducted in-depth and detailed research on various types of lithium iron phosphate, continuously improved equipment, and carried out technical exchanges with lithium battery material factories, including feedback and summary of test results. Thanks to the efforts of the staff of SAC Powder, all the lithium iron phosphate projects have been delivered.

In 2013, after applying the closed-loop technology to the production of lithium iron phosphate in a plant in Qinghai, many lithium battery material factories in Hunan, Hubei, Guizhou, Jiangxi, Fujian, Shandong and other provinces have chosen the nitrogen closed-loop grinding production line. The domestic famous production line contractor design unit, all designated SAC powder as the supporting crushing equipment partner.

Nitrogen closed loop grinding is characterized by zero impurity introduction, strict control of moisture, stable particle size of products, unified configuration of production capacity according to the kiln, reasonable power saving, can ensure 24 hours *365 days of continuous and stable production.

With the continuous change of the process route of lithium electric materials, SAC Powder constantly adjusts the equipment configuration to improve the product performance. Through the extensive field experience, the equipment performance becomes more mature and stands out from the competition in the industry. This is the result of the joint efforts of SAC powder people, and also comes from the consistent trust and support of hundreds of users for years.
