Product Overview
The Electromagnetic Separator for Find Powder consists of a carbon steel housing and an internal electromagnetic coil, forming an electromagnetic field circuit. An electromagnetic field is generated at the center of the coil. A barrel filled with a magnetic concentrator passes through the coil, where the magnetic field is captured and amplified, creating a high-gradient, high-field-strength separation zone. As material passes through the concentrator, magnetic materials are attracted to the medium, allowing non-magnetic materials to pass through smoothly, thus separating magnetic impurities.
Two counter-rotating vibration motors are installed on the barrel, applying high-frequency vibrations up and down to the barrel, ensuring the passage of ultrafine materials.
A three-way dispensing valve is installed below the magnetic screen. This valve is controlled by a PLC program, enabling automatic iron removal and slag discharge.
Key Selling Points
● The magnetic media features 22 layers, with both the number of layers and the height of the magnetic field area 25% higher than comparable brands on the market. The greater the number of layers, the more magnetic material can be captured under the same demagnetization conditions, resulting in a 20-25% higher efficiency than comparable models. The capture probability of magnetic material in the material is increased by 5-10%.
● Due to the fragility of stainless steel threads, the media is secured with standard components. For the same specification, our demagnetizer spare parts costs can be reduced by 50-70% annually.
● The demagnetizer is equipped with a media removal arm, making media cleaning and maintenance more convenient and quick for frontline workers. For the same specification, our demagnetizer reduces daily maintenance labor costs by 50-70%, while increasing efficiency by over 30%.
● The unique internal oil circulation design of the cooling system ensures heat dissipation of the electromagnetic coil, preventing localized temperature rise and damage. Assuming proper cooling water circulation and regular maintenance, our company guarantees a service life of over 10 years for the electromagnetic coil.
● The control system utilizes a constant current design for electromagnetic coil excitation (PLC automatic voltage regulation), eliminating the need for manual adjustment due to a decrease in the magnetic field caused by rising coil temperature.
● The unique structural design of the automatic dispensing valve eliminates bolts and other removable parts on the material channel. This ensures a tight seal while preventing loose bolts during long-term operation, which could lead to foreign matter being mixed into the material.
● The material channel can be sprayed with PTFE/ETFE to reduce the risk of magnetic foreign matter being introduced.
Working Principle
A solenoid coil housed in a steel shell produces a uniform background magnetic field across the coil openings. Expanded metal disks (the magnetic medium) fill the openings. The background field induces amplified localized high‑gradient nodes in the medium; as powders pass through, magnetic particles are captured in these nodes and removed from the particle stream. Vibration or pneumatic flow assists material throughput and separation efficiency. Configurations can include pulse or demagnetization modes to minimize residual magnetization of product.

Frequently Asked Questions
Q: What particle sizes can this separator handle?
A: Designed for powders below 50 μm; many materials in the 0.5–50 μm range respond well. Final performance depends on magnetic susceptibility, particle size distribution and feed conditions — sample testing recommended.
