Description

Technical Field

[0001] The utility model relates to the technical field of micro powder processing equipment, in particular to a lithium battery micro powder material processing device. Background Art

[0002] Airflow mills are widely used in the micropowder processing industry due to their wide range of applications and high finished product fineness. Together with a cyclone separator, dust collector, and induced draft fan, the airflow mill forms a complete micropowder production system. After being filtered and dried, compressed air is injected at high speed into the grinding chamber through a Laval nozzle. At the intersection of multiple high-pressure airflows, the material is repeatedly pulverized by collision, friction, and shearing. Driven by the fan's suction, the pulverized material moves with the rising airflow to the classification zone. The powerful centrifugal force generated by the high-speed rotating classification turbine separates the coarse and fine materials. Fine particles that meet the required particle size pass through the classification wheel and are collected in the cyclone separator and dust collector, while the coarse particles descend to the grinding zone for further pulverization.

[0003] However, as the industry develops, companies are placing increasingly stringent demands on micropowder production equipment. This existing equipment is gradually becoming inadequate. Currently, a single set of micropowder production equipment can only process a specific powder material using a specific process, resulting in a relatively limited functionality. Different material characteristics and / or production processes require different equipment. To meet production requirements, more equipment must be deployed to handle micropowder processing under varying conditions. This not only introduces significant inconvenience and reduces production efficiency, but also increases equipment investment and production costs.
