The electromagnetic dry powder magnetic separator reduces magnetic
impurities in sodium battery materials to below 1ppm
The separation principle of sodium battery materials by the fully
automatic electromagnetic dry powder magnetic separator
The separation principle of sodium battery materials by the fully
automatic electromagnetic dry powder magnetic separator mainly
relies on the adsorption effect of the magnetic field generated by
electromagnetic induction on magnetic substances. When sodium
battery materials pass through the magnetic separator, magnetic
impurities (such as mixed iron, nickel, cobalt and other metal and
compound particles) in them will be adsorbed onto the magnetic
medium under the action of the magnetic force. Sodium battery
materials themselves are usually non-magnetic or weakly magnetic
and are not subject to obvious magnetic field forces, thus being
able to continue moving forward with the material flow. After
passing through the magnetic field area, the sodium battery
material was initially separated from the adsorbed magnetic
impurities. Non-magnetic sodium battery materials are discharged
from the discharge port of the magnetic separator. The magnetic
impurities adsorbed on the magnetic medium gradually increase. When
the power is cut off, the electromagnetic coil loses its magnetism,
and the magnetic medium demagnetizes. At the same time, the
vibration or scraper device is activated to make the magnetic
impurities adsorbed on the magnetic medium fall off and be
discharged from the slag outlet, thus completing a complete iron
removal cycle process. This ensures that the iron remover can work
continuously and stably, and constantly purify the silicon-carbon
anode material.
Why is a fully automatic electromagnetic dry powder iron remover
used for the purification of sodium battery materials
The JC fully automatic electromagnetic dry powder magnetic
separator features high background field strength, excellent
demagnetization effect, low coil temperature rise and high
reliability. The special material medium network with different
structures can quickly adsorb iron filings, iron powder and other
impurities, ensuring the purity of the materials.
After a certain sodium battery material technology company in China
adopted the JC fully automatic electromagnetic dry powder iron
remover, the purity of the sodium battery material achieved a
purification effect of ppb level iron content. Moreover, the
equipment operates stably with low maintenance costs. Each year, it
can save the manufacturer about 600,000 yuan in product losses and
additional processing costs caused by excessive impurities,
bringing good economic benefits to the manufacturer.
Improvement and Benifit
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.
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.
