Dry powder magnetic separator - Removes metal impurities from graphite materials of lithium batteries, with a purity of up to 99.9%
The necessity of dry powder magnetic separators in the separation of lithium battery anode materials
The anode materials of lithium batteries are mainly natural graphite and artificial graphite. During the production and processing, the materials are prone to be mixed with dust, burrs or metal impurities. These impurities, especially metallic impurities, can cause self-discharge of the battery, and even lead to battery combustion and explosion, resulting in safety accidents. Therefore, it is necessary to remove metallic impurities from the negative electrode material, and dry powder magnetic separators play a key role in this process.
The advantages of JC dry powder magnetic separator
JC dry powder magnetic separator features high background field strength, good demagnetization effect, low coil temperature rise and high reliability. It can be matched with magnetic separation media according to different materials to meet the demand of lithium battery industry customers for impurity removal of anode materials. Moreover, we match different key components in the equipment details for different battery materials to achieve the removal rates of metal impurities and magnetic foreign substances for different battery materials. In the production process of a leading lithium battery anode material manufacturer and processing plant
in China, despite adopting multiple procedures, there were still trace amounts of metal impurities remaining, which led to unstable batch qualification rates of the products. Later, after introducing the JC electromagnetic dry powder magnetic separator, the removal rate of metal impurities in the anode material increased from the original 85% to 99.8%. The batch qualification rate of the products has remained stable at over 99%, successfully meeting the strict requirements of high-end customers for material purity and further consolidating its leading position in the market.
Improvement and Benifit
More reliable mechanical structure: Dry separation equipment faces challenges of vibration and sealing in practical applications. JC ensures sealing by improving the pipeline structure and eliminates pipeline leakage. Moreover, JC adopts exclusive customized shock absorption and buffering components, fundamentally reducing the vibration of the dry magnetic separator and increasing the trouble-free operation time of the equipment.
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.
