Dry Magnetic Separator For Lithium Battery Cathode Material Separation Of Iron Impurities Efficient Increased 20%

Dry Magnetic Separator for lithium battery cathode material separation of iron impurities efficient increased 20%

The working principle of the dry magnetic separator used for the purification of cathode materials in lithium batteries:

The cathode materials of lithium batteries usually exist in powder form. When these powder-like cathode materials pass through a dry magnetic separator, the magnets inside the magnetic separator generate a magnetic field. Because ferromagnetic impurities have magnetic properties, they will be adsorbed on the magnetic components of the magnetic separator under the action of the magnetic field, or be attracted to the area with a higher magnetic field intensity. The cathode materials of lithium batteries themselves generally do not have magnetism or have very weak magnetism, and are not subject to obvious magnetic force, thus being able to separate from ferromagnetic impurities and achieve the purpose of purification. For instance, in the production of some lithium batteries that use lithium cobalt oxide, lithium manganese oxide, lithium iron phosphate and ternary materials as cathodes, dry magnetic separators can effectively remove impurities such as iron filings and iron powder that are mixed in during raw material processing and mixing.

Why is a dry magnetic separator used for the purification of cathode materials in lithium batteries

It does not require the use of liquid as the medium, avoiding problems such as material dilution and subsequent drying that may occur in the wet magnetic separation process, simplifying the process flow and improving production efficiency.

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. After a certain ternary Lithium (NMC Lithium) cathode material manufacturer in China applied JC's dry magnetic separator, while ensuring that the purity of the output after separation reached 99.99%, the separation capacity was increased by 20%, helping the user achieve a 190% increase in output value from 2020 to 2023.
