Slurry De-Iron Filter XN-FTM-2L
SKU: XN-FTM-2L
Slurry De-Iron Filter XN-FTM-2L is a combined magnetic de-iron and vacuum filtration unit for the optimization step between slurry mixing and electrode coating in lithium-ion battery manufacturing. The unit removes both ferromagnetic contamination (via removable permanent magnets at 8,000–10,000 Gauss) and oversize hard particles (via a vacuum-driven filtration screen) in a single batch process.
XN-FTM-2L handles 2 L per batch, accepts mesh sizes up to 1000-mesh (80–120 mesh recommended for typical lithium-ion electrode slurries), and is suitable for slurries up to 20,000 cP viscosity and 80% solid content. The all-stainless-steel build supports thorough cleaning between cathode and anode runs.

Name: Slurry De-Iron Filter XN-FTM-2L
Equipment Type: Combined Magnetic De-Iron and Vacuum Filtration Unit
Product Code:XN-FTM-2L
Brand: Xnergy
Product Introduction:
Slurry De-Iron Filter XN-FTM-2L is a combined magnetic separation and vacuum filtration unit designed for slurry optimization between mixing and electrode coating in lithium-ion battery manufacturing. Removable high-strength permanent magnets capture ferromagnetic contamination (Fe, Ni, magnetic alloys) from cathode and anode slurries, while a vacuum-driven filtration screen below removes oversize hard particles in the same batch. The all-stainless-steel construction supports thorough cleaning between cathode and anode runs, and the removable magnet design simplifies routine maintenance.
Working Principle:
Slurry is poured into the upper chamber, where permanent magnets capture ferromagnetic particles. Vacuum then draws the slurry through a fine filtration screen into the lower chamber, removing oversize hard particles. Once filtration is complete, a discharge valve is opened to transfer the optimized slurry to the next process step.
Key Features:
Dual-action slurry treatment — magnetic de-iron + vacuum filtration in one batch
Removable permanent magnets at 8,000–10,000 Gauss for efficient capture of ferromagnetic contamination
Easy magnet removal for cleaning and inspection
All-stainless-steel construction for corrosion resistance and cleanability
Filtration mesh up to and including 1000-mesh (80–120 mesh recommended for lithium-ion electrode slurries)
Suitable for slurries up to 20,000 cP viscosity and 80% solid content
Discharge valve for controlled slurry transfer to downstream process
Improves slurry uniformity to support coating consistency

Application Areas:
XN-FTM-2L is suitable for:
Optimizing lithium-ion battery cathode and anode slurries between mixing and coating
Removing ferromagnetic contamination (Fe, Ni, magnetic alloys) that would otherwise cause internal short-circuit risk in finished cells
Removing oversize hard particles that would otherwise cause coating streaks or pinholes
Pilot and small-production electrode preparation workflows where slurry consistency and coating yield matter
Maintenance:
Clean the equipment regularly with a soft cloth lightly moistened with alcohol
Lubricate moving parts periodically to ensure smooth operation
If the equipment is not used for an extended period, clean the moving surfaces and apply a protective anti-rust coating
Periodically inspect screws, nuts, pins, and other fasteners to prevent loosening
Remove and clean the permanent magnets between batches to maintain de-iron efficiency
Safety Notes:
Do not place hands or other body parts near moving components or work-zone areas during operation
Operation should be performed by a single trained operator to avoid accidental injury
Disassembly should only be performed by qualified technicians
Handle the strong permanent magnets with care during cleaning — keep clear of magnetic-sensitive electronics, pacemakers, and tools
Specifications are provided for reference and may be adjusted to suit specific process requirements. Custom mesh sizes are available on request.
Note: Specifications listed above are typical and for reference only. Actual filtration and de-iron performance depend on slurry viscosity, solid content, contamination level, and operating conditions. XN-FTM-2L is a quality-critical step in lithium-ion electrode manufacturing — ferromagnetic contamination above a few ppm can cause cell-level micro-shorts during formation, which is why magnetic de-iron is required for cathode active materials such as NCM, NCA, LFP, and LMFP. For users who only need hard-particle removal without magnetic separation, the simpler benchtop XN-FT-2L, XN-FT-1L, and XN-FT-500mL slurry filters offer a lower-cost option. Upstream slurries for XN-FTM-2L are typically prepared in the XN-PVM-5L or XN-PVM-2L planetary mixer, and the filtered, de-ironed slurry feeds the Slot-Die Coating System XN-SDC for precision coating. For cathode materials whose slurries benefit most from de-iron treatment, see our Cathode Materials catalog (LFP, NCM, NCA, LMFP).
