Technical characteristics
Innovative magnetic circuit design, improve the utilization rate of magnetic energy, so that the magnetic field strength of the selection is increased by more than 8%, the background field strength can reach 9000GS.
The shell of the excitation coil adopts a fully sealed structure, which has the characteristics of moisture-proof, dust-proof, anti-corrosion, etc., and can work in harsh environment.
Using oil-water composite cooling method, the excitation coil heat dissipation is fast, the temperature rise is low, and the magnetic field thermal attenuation is small.
The magnetic medium with different structure of special materials has large magnetic field gradient and good iron removal effect.
The iron removal process and iron discharge process are carried out by vibration mode, and the iron removal is clean.
The material distribution box is equipped with a material stopper structure to solve the material leakage phenomenon around the flip plate, and completely separate the iron powder and basic materials.
