Description

Complete system for crushing, demagnetizing and packaging lithium carbonate by air flow Technical Field The utility model relates to the technical field of lithium carbonate processing structures, in particular to a complete system for crushing, demagnetizing and packaging lithium carbonate by air flow. Background Lithium carbonate plays a significant role as an important lithium salt product in the modern industrial field, especially in the new energy battery industry. With the rapid development of the new energy automobile industry, the demand for high-purity lithium carbonate with uniform granularity is continuously rising, and in the production process of lithium carbonate, jet milling, demagnetizing and packaging are vital links. When traditional jet milling equipment pulverizes lithium carbonate, the granularity distribution is difficult to control accurately, and the product quality is uneven. On the one hand, too coarse particles can affect the charge and discharge performance of the battery and reduce the energy density of the battery, and on the other hand, too fine particles can cause agglomeration phenomenon and are also unfavorable for subsequent processing and application. And if the lithium carbonate contains magnetic impurities, the performance of the lithium carbonate in products such as batteries and the like can be seriously affected. However, the existing demagnetizing device has lower demagnetizing efficiency and cannot meet increasingly strict product quality standards. In addition, secondary pollution to lithium carbonate is also possibly caused in the process of demagnetization, and the product quality is further influenced.
