Electromagnetic Slurry Magnetic Separator 3

Electromagnetic Slurry Magnetic Separator

The Electromagnetic Slurry Magnetic Separator is a key piece of equipment designed to separate magnetic minerals from slurry using a controllable electromagnetic field. Its core mechanism relies on excitation coils to generate a powerful, adjustable magnetic field reaching up to 2.0 Tesla, making it ideal for processing finely disseminated or weakly magnetic ores in beneficiation plants. Additionally, a variety of specialized magnetic stainless steel media are available to meet specific mineral processing requirements across different regions and ore types.

This equipment is suitable for the efficient iron removal and purification of fine-grained non-metallic minerals, such as feldspar, silica sand, nepheline, fluorite, kyanite, kaolin, talc, and bentonite. It is also applicable to other rare earth minerals including hematite, wolframite, and manganese ore. Additionally, it is used for the removal of trace magnetic substances from battery anode/cathode slurries, as well as electronic and chemical slurries.

ADVANTAGES

1.Efficient Cooling & Stable Magnetic Field: The excitation coils feature a fully sealed oil-cooling design, paired with an external high-efficiency oil-water heat exchanger to achieve composite cooling. This ensures rapid heat dissipation and low temperature rise, guaranteeing a highly stable magnetic field.

2.Ultra-High Gradient & Strong Separation: The separation matrix utilizes specialized magnetically conductive stainless steel. Under the excitation of the background magnetic field, it generates an ultra-high gradient field, providing powerful capture force for low-grade, weakly magnetic minerals and significantly enhancing separation efficiency.

3.Fully Automatic Operation & Low O&M Costs: Controlled by an automated program, the equipment enables unattended, fully automatic operation, effectively reducing operational and maintenance expenses.

4.High-Pressure Back & Forward Flushing: The cleaning stage employs high-pressure water flushing in both forward and reverse directions. The flushing duration can be flexibly set based on mineral characteristics and processing stages, ensuring the matrix is free of residue for a clean separation while boosting overall processing efficiency.

PRODUCT STRUCTURE

During operation, direct current is supplied to the excitation coils, generating an induced magnetic field of up to 20,000 Gauss on the surface of the magnetic media within the separation zone. The slurry is pumped from the bottom inlet pipe by a slurry pump equipped with a variable frequency drive (VFD) motor. After entering the lower yoke, the slurry is evenly dispersed and flows through the gaps into the magnetic media separation zone. Magnetic particles are firmly captured on the surface of the magnetic media, while non-magnetic particles pass through and are discharged from the outlet via the upper yoke.After a set period, when the magnetic media is saturated with captured particles, the control system automatically initiates the return cycle. The excitation coils remain energized; the feed valve closes, and the return valve opens to flush residual slurry back to the feed tank. Once the chamber is drained, the return valve closes, and the system enters the cleaning cycle. The excitation coils are de-energized to eliminate the magnetic field. Subsequently, the tailings and flushing valves open, utilizing forward and reverse high-pressure water jets combined with pulsed high-pressure air to thoroughly scour the media. This ensures the complete release of magnetic particles into the collection chute. Finally, the valves close, and the system automatically begins the next cycle.
