What are the uses of adding iron separators to lithium battery material vibrating screens?

In the production process of lithium-ion battery cathode materials such as lithium cobalt oxide, lithium manganate, ternary materials, and lithium nickel cobalt oxide materials, trace amounts (mass percentage less than 0.1%) are caused by various reasons such as equipment and pipeline wear. Iron filings are mixed in the material. A small amount of iron filings in a lithium-ion battery will form a micro-battery, reducing the specific capacity of the lithium-ion battery, severely piercing the lithium-ion battery diaphragm, and even causing the lithium-ion battery to explode. Therefore, these iron filings need to be removed during the production process of using the vibrating screen. Because the iron filings and lithium battery materials have similar meshes and are relatively fine, the traditional vibrating screening equipment is not easy to sort. At this time, a special vibration is required. Screening equipment for removing iron filings-iron-removing vibrating screen.

The shape of the lithium battery material vibrating screen is circular. The operating principle of the device is that the screen meshes three-dimensionally under the action of a vertical vibrating motor. Through the action of the ultrasonic wave device, the lithium battery material is suspended on the screen surface at low altitude, thereby solving the lithium battery positive and negative electrode materials. Internet blocking problems such as static electricity, theater troupes, and adsorption. The iron removal vibrating screen is based on the original vibrating screen and then the feed port is equipped with a separator. During the feeding process, the material first passes through the iron removal silo, and the magnetic rod in it will absorb the iron filings in the material to achieve the removal of iron filings. .

The iron-removing vibrating screen can effectively improve the quality memory of lithium battery positive and negative materials, reduce labor costs while not affecting the quality of the positive and negative materials, and improve the accuracy and quality of materials.
