[0047] Specifically, the high-frequency alternating magnetic field module consists of: High-frequency generator: outputs 1-10kHz sinusoidal AC power (voltage adjustable from 0-220V), using IGBT inverter technology (efficiency > 95%). Matrix magnetic pole array: A pair of Helmholtz coils (diameter 50 mm, 100 turns) is embedded between the original N / S pole magnetic strips (65 / 66) of the triangular inclined plane (61), with the coil axis at a 30° angle to the normal of the inclined plane. Shielding shell: The coil is wrapped with μ-metal (permeable magnetic alloy) to reduce magnetic field leakage (leakage rate < 3%).

[0048] More specifically, high-frequency skin effect; Apply a 1-10 kHz high-frequency alternating magnetic field to force the current to concentrate on the metal surface: the current density J increases with the frequency f: The current density of titanium alloy increases by 3.2 times at 10 kHz (compared to 50 Hz power frequency).

[0049] Physical nature: Under high-frequency magnetic field, a skin depth δ is formed inside the metal: ω: angular frequency; μ: magnetic permeability The smaller the δ (e.g. δ ≈ 5.7 mm at 10 kHz), the more concentrated the surface current, and the vortex current force is significantly enhanced.

[0050] Optimization of Lorentz force direction: The axis of the Helmholtz coil is at a 30° angle to the normal of the sorting inclined plane (key design): The magnetic field B is at a 60° angle to the material speed v (down the inclined plane).

[0051] Maximize the vertical component of the Lorentz force F = q(v × B): F⊥=Fsin60∘=0.866F.

[0052] This component directly opposes the gravitational component mg cosθ, pushing the weakly conductive metal laterally.

[0053] Magnetic field strength threshold: Weakly conductive metal sorting requires: F⊥>μmg cosθ (μ: friction coefficient); Substitute the titanium alloy parameters (mass m = 10g, inclined plane angle θ = 35°; Critical magnetic field strength B>0.48T (when f=10kHz).

[0054] Therefore, the system is set to work at a magnetic field strength of ≥ 0.5 T.

[0055] By concentrating the current through high-frequency skin effect and optimizing the force direction through a 30° magnetic field inclination, the bottleneck of weakly conductive metal sorting is broken, and the gap in titanium / magnesium alloy efficient recovery technology is filled.
