High-intensity dry type electromagnetic separator precisely removes ultra-fine ferrous contaminants — including micron and sub-micron impurities — from dry powders and granular materials, ensuring exceptional material purity without water or additives. Watch the full 1-minute performance demo.
Ideal for removing fine and weakly magnetic impurities from dry, non-metallic materials. Widely used in mining, chemical, electronic, and new energy industries to achieve high product purity and equipment protection:
The Dry Type Electromagnetic Separator from MAG SPRING delivers precision ferrous removal for dry material processing in industries that demand absolute purity. It efficiently captures fine ferromagnetic particles (down to sub-micron) from powders and granules — such as lithium battery materials, food powders, ceramics, plastics, and pharmaceuticals — ensuring high-grade quality, safety, and production efficiency.
| Ultra-fine Ferrous Separation Effectively removes micro-metal impurities invisible to conventional systems, reaching micron-level precision for battery-grade purity. |
Optimized FEA Design Finite-element analyzed (FEA) coils ensure maximized magnetic field intensity (up to 2.4T) and uniform flux distribution throughout the matrix. |
Advanced Cooling & Stability Oil circulation and forced heat-dissipation design maintain stable peak performance during 24/7 heavy-duty operation without magnetic decay. |
| H-Class Insulation System Transformer-grade H-class insulation ensures a stable service life exceeding 10 years even in harsh, high-temperature industrial environments. |
Integrated Vibration System Dual-symmetrical vibration prevents powder caking and ensures high-frequency, complete discharge of captured contaminants during cleaning cycles. |
Smart Industry 4.0 Ready PLC + PID-controlled excitation with remote monitoring, constant magnetic field control, and automated fault diagnosis technology. |
* Special configurations available for Powder Metallurgy (iron powder pre-purification) and high-viscosity battery powders.
The dry type electromagnetic separator utilizes high-intensity energized coils to create a powerful magnetic matrix. As material flows through, ferrous impurities are trapped. During the automated cleaning cycle, the magnetic field is deactivated, and the vibration system ensures all trapped metals are flushed out.

Q1. What particle size can the dry electromagnetic separator remove?
A: It is specifically engineered to capture micro-ferromagnetic particles as small as 0.1 µm, providing a much higher purity grade than permanent magnet systems.
Q2. Can it handle sticky or hygroscopic powders?
A: Yes. The system features an integrated symmetrical vibration unit that prevents material bridging or caking, ensuring a steady flow and efficient contaminant discharge.
Q3. What is the difference between dry type and wet type separators?
A: Dry type separators are designed for air-conveyed or gravity-fed powders and granules. Wet type separators utilize a liquid carrier (slurry) to transport materials through the magnetic matrix.
Q4. How often does it need cleaning?
A: Cleaning is fully automated. The PLC manages the cycle based on your material’s impurity load, ensuring the system remains at peak magnetic efficiency without manual labor.
