Demagnetizing Coil System
In heavy-medium separating system, the ferromagnetic mineral powder can easily form conglomeration with rapid sedimentation and poor stability.Constant Magnetic Field Demagnetize can remarkably slower the medium sedimentation and improve stability.
In a heavy-medium separating system, after wet drum magnetic separators to the recovery of pulps containing magnetic solids.
The only amount of individual particles forms magnetic floes.
Such as precision ground, honed or machine steel is often magnetized.
The Ejet demagnetizing coil will remove magnetism, remarkably slower the medium sedimentation, and improve stability. Constant Magnetic Field Demagnetizer is applied to break aggregated ferrous particles in magnetic separation, to improve dual-stage classification efficiency.
Demagnetizing Coil System
Product Features
1) Non-magnetic pipe made of special sturdy material protective surface, will protect magnetic field in coil inside from harm.
2) The magnetic high-intensity coil generated is a high-frequency alternating, step-winding design, that decreases along the axle.
3) Ore pulp running through the pipe is magnetized in both directions.
4) Demagnetize individual remanence in the ferrous particles/materials, reduced gradually to none.
5) Easy installation, compact structure, lightweight, and no maintenance required.
A demagnetizing coil is an electromagnetic device used to reduce or eliminate the remnant magnetic field (remanence) in ferromagnetic materials, a process commonly known as degaussing or deperming. These coils function by subjecting a magnetized object to an external alternating magnetic field that gradually decreases in intensity, thereby disrupting the alignment of the material’s internal magnetic domains (Weiss domains) and leaving them in a state of homogeneous disorder.
Principles of Operation
The fundamental mechanism of a demagnetizing coil relies on the concept of magnetic hysteresis. When a ferromagnetic material like iron or steel is exposed to a strong magnetic field, its internal domains align, creating a net magnetic field. To reverse this, a demagnetizing coil generates an alternating current (AC) field. As the AC cycles, it repeatedly reverses the polarity of the domains. For the process to be successful, the peak field strength (H) must be sufficient to overcome the material’s coercivity (Hc).
