mineral processing equipment

The single-roll rapid quenching combined with the PTMS MAGNETIC SEPARATION method cools NdFeB melt at a rate of 10 ⁶℃/s to produce amorphous thin strips with thickness ranging from 20 to 50 μm. After crystallization treatment, nanocrystals measuring 10-20nm are formed, achieving a coercivity (Hcj) of 18kOe and enhancing the magnetic breakage toughness to 8 MPa·m¹/². This innovation effectively addresses the longstanding challenges of material brittleness and processing difficulties in conventional demagnetization equipment magnets.

PTMS MAGNETIC SEPARATION

This thin-belt magnet has been applied in the drive motor of PTMS MAGNETIC SEPARATION, achieving a 30% reduction in motor size and a power density of 3.5 kW/kg. The dual-roll rapid-quenching PTMS MAGNETIC SEPARATION equipment, through optimized roll surface roughness (Ra=0.8 μm) and cooling rate gradients, has increased the thin-belt yield from 65% to 85%, reduced costs by 25%, and is currently undergoing mass production trials.

what is magnetic separation method for concentration of ore？

Anisotropic bonded magnet technology integrates powder orientation with injection molding to meet the integrated manufacturing demands of PTMS MAGNETIC SEPARATION for complex-shaped magnets. The magnetorheological injection molding PTMS MAGNETIC SEPARATION deironing process applies a 1.5T instantaneous magnetic field during injection, achieving 80% orientation degree of magnetic powder. The resulting irregularly shaped magnets attain a magnetic energy product of 16 MGOe, representing a 120% improvement over traditional isotropic bonded magnets.
