Self-cleaning rotary magnetic separator, specially designed for
iron removal from positive and negative electrode materials of
lithium batteries, with PPM-level precision guaranteed
In the field of lithium battery production, the purity of positive
and negative electrode materials plays a decisive role in the
performance, lifespan, and safety of batteries. Even extremely
trace amounts of iron impurities may cause internal short circuits
during the charging and discharging process of lithium batteries,
reduce the charging and discharging efficiency of batteries, and
seriously affect the overall quality of batteries. The self -
cleaning rotary iron remover emerges as the times require. It
precisely targets the iron removal problem of positive and negative
electrode materials of lithium batteries and provides reliable
solutions for lithium battery production enterprises.
The self - cleaning rotary iron remover is specially designed for
iron removal of positive and negative electrode materials of
lithium batteries, and its structure and function are in line with
the needs of lithium battery production. The equipment adopts an
advanced annular grille rotating design, and the annular grille is
driven by a reduction motor to rotate continuously. When materials
flow through the iron remover, it can effectively avoid bridging,
blockage and other situations, ensure the smooth passage of
materials, and strongly adsorb iron impurities in them. The high -
quality permanent magnet carried inside can generate a strong
magnetic field of up to 15,000 Gauss, which can accurately capture
the tiny and imperceptible iron particles in the positive and
negative electrode materials, achieving high - precision iron
removal at the PPM level and building a solid defense for the
purity of positive and negative electrode materials of lithium
batteries.
A1: The equipment realizes the self - cleaning process through the
rotating annular grille. During operation, the iron impurities
adsorbed on the magnetic rods of the grille will automatically fall
off at specific positions as the grille rotates. The cleaning
frequency can be adjusted according to the iron content in the
actual production materials and the production rhythm. Users can
simply set the cleaning cycle through the intelligent control
system of the equipment to meet different iron removal needs and
ensure that the equipment always maintains an efficient iron
removal state.
A2: The iron remover has good temperature resistance performance,
and the applicable temperature range is 60 - 350℃. In common high -
temperature links in lithium battery production, such as the
conveying process after some material sintering and drying
processes, the iron remover can operate stably, the magnetic field
strength will not be significantly attenuated due to high
temperature, and key components such as magnetic rods can also
maintain structural stability and continue to play an efficient
iron removal role.
A3: The equipment fully considers the iron removal needs of
materials with different particle sizes during design. The magnetic
rod gap and material channel are reasonably designed. Whether it is
extremely fine powdery positive and negative electrode materials or
raw materials with slightly larger particles, it can ensure the
smooth passage of materials and effectively adsorb iron impurities
in them. For fine iron particles, the strong magnetic field can
provide sufficient adsorption force; for larger iron impurities,
there will be no blockage of the channel, ensuring a stable iron
removal effect on positive and negative electrode materials with
different particle sizes.
A4: In terms of installation, the equipment is designed with
standardized installation interfaces, which can be conveniently
connected to common lithium battery production pipeline systems.
For personnel with certain mechanical installation knowledge, the
installation can be completed with reference to the detailed
installation instructions. Of course, if enterprises have needs, we
also provide professional personnel to install on - site. In terms
of maintenance, the equipment structure is simple. Daily, only the
operation of the equipment and the adsorption effect of the
magnetic rods need to be checked regularly. The self - cleaning
function greatly reduces the workload of manual cleaning and lowers
the maintenance difficulty and cost.
A5: In addition to iron removal of positive and negative electrode
materials of lithium batteries, in the lithium battery slurry
mixing link, and the material conveying process before subsequent
electrode coating and battery assembly processes, as long as there
may be iron impurities in the materials, this iron remover can play
a role in ensuring the purity of materials in the entire lithium
battery production process and providing all - round iron removal
support for the production of high - quality lithium batteries.
