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.
