Frequently Asked Questions
What materials are suitable for this magnetic separator?
It is ideal for nonmagnetic, dry fine powders or granules (typically 8 meshes) with an iron content of ≤1%, such as feldspar, quartz, kaolin, frit, pigment, and battery powder.
What is the maximum magnetic induction intensity of these separators?
Depending on the model, the magnetic induction intensity ranges from 16,000 Gs up to a maximum of 18,000 Gs, with background field strengths reaching up to 9,000 Gs.
How does the cooling system work on this equipment?
The separator utilizes an oil-water composite cooling method, which ensures rapid heat dissipation from the excitation coil, maintains a low temperature rise, and minimizes thermal attenuation of the magnetic field.
How is material leakage prevented during operation?
The material distribution box features a specialized material stopper structure that prevents leakage around the flip plate, completely separating the iron powder from the basic materials.
How is the accumulated iron removed and discharged?
Both the iron removal and iron discharge processes are driven by a vibration mode, ensuring that the separated magnetic impurities are thoroughly and cleanly discharged.
