The RPS semi-automatic permanent-magnet iron remover (model RPS-4-DN80-150) works at a system pressure of 1.0 MPa, handles cathode slurry with a viscosity of 4000–35000 mPa·s at 5–65 ℃ and a density of 1.8–2.5 g/cm³, and provides a magnetic field strength of ≥12000 GS. The permanent-magnet circuit removes magnetisable metal impurities from slurries and is widely used for in-line iron removal and purification of lithium battery electrode slurries.
