Dry powder magnetic separator used in LFP LiFePO4 Battery cathode materials has increased the separation efficiency of iron impurities by 20%

The separation principle of lithium iron phosphate (LFP) cathode materials by dry powder magnetic separators
Lithium iron phosphate (LFP) cathode material itself is a weakly magnetic or non-magnetic substance. During the production process, some magnetic impurities may be mixed in, such as particles of metallic elements like iron, nickel and cobalt or their compounds. The magnetic properties of these magnetic impurities are relatively strong, forming a significant magnetic difference with the lithium iron phosphate cathode material, which is the basis of magnetic separation.
The JC dry powder magnetic separator is equipped with a magnetic field device inside. When the dry powder of lithium iron phosphate (LFP) cathode material containing magnetic impurities enters the magnetic field area of the magnetic separator, under the action of the magnetic force, the magnetic impurities are adsorbed onto the magnetic poles or magnetic rollers of the magnetic separator. With the rotation of the magnetic rollers or the action of other discharge devices, they are separated and collected in specific containers. The unadsorbed lithium iron phosphate (LFP) cathode material was collected as a product in another container, thereby achieving the separation of the lithium iron phosphate (LFP) cathode material from magnetic impurities.

Why is a dry powder magnetic separator used for the purification of LFP cathode materials
Lithium iron phosphate (LFP) cathode materials usually exist in dry powder form. The JC dry powder magnetic separator is specially designed for dry powder materials and can directly process dry powder cathode materials without additional pretreatment or conversion processes, simplifying the process flow and improving production efficiency. The JC dry powder magnetic separator operates stably and reliably, which increases the trouble-free operation time of the equipment.
After a certain lithium iron phosphate (LFP) cathode material manufacturer in China applied JC's dry magnetic separator, the quality of the lithium iron phosphate cathode materials produced by the company was significantly improved. The magnetic impurity content of the products was greatly reduced by 18%, and the performance became more stable and reliable. It meets the high requirements for lithium iron phosphate cathode materials in multiple fields such as electric vehicles, electric ships, and large-scale wind and solar energy storage, enhancing the competitiveness of the product in the market.

Improvement and Benifit

Ensure the purity of the product: The dry magnetic separator can precisely control the magnetic field intensity and material flow rate. According to the characteristics of different lithium battery cathode materials and impurity content, it can flexibly adjust the circuit and magnetic field parameters to achieve efficient removal of magnetic impurities and ensure the purity of the product.

Efficient separation work: Over 20 Chinese lithium battery cathode material enterprises have adopted JC's dry magnetic separator. We collaborate with user enterprises to continuously optimize the inclination Angle of the feed flap valve based on different raw materials, optimize the discharge port, precisely control the material flow rate, and strive to enhance the separation capacity while ensuring the purity of the output.
