Product Overview
The Electromagnetic Separator for Slurry is engineered to efficiently capture ferromagnetic and certain paramagnetic particles from slurry streams. An optimized electromagnetic coil and magnetic core create a strong, uniform, and adjustable magnetic field across the separation trough. Magnetic particles are attracted to removable pickup elements (plates, rods or rollers). Captured material is discharged by demagnetization, mechanical scraping or automatic backwash, enabling continuous operation and easy recovery.
1. Slurry flows through the separation trough.
2. Energized coil generates a magnetic field; magnetic particles deviate from flow lines and adhere to pickup elements.
3. Accumulated material is removed by scheduled demagnetization + scraper or by backwash.
4. Recovered solids are collected for disposal or value recovery; slurry continues downstream with greatly reduced magnetic contamination.

Benefits & Advantages
● High capture efficiency for fine magnetic particles, improving downstream product purity.
● Modular, maintainable design reduces downtime and parts replacement cost.
● Energy efficient via precise current control and optional cooling for long duty cycles.
● Flexible configurations to meet corrosive, sanitary, or high‑temperature requirements.
● Scalable to meet large throughput demands through parallel installations.
Installation & Operation Notes
● Provide slurry flow rate, solids concentration, particle size distribution, temperature and pH for accurate sizing.
● Ensure adequate electrical supply, grounding and cooling water (if applicable).
● Integrate PLC/HMI for automated backwash cycles, current control and alarm handling.
● Monthly checks of electrical connections, coil insulation and cooling system.
● Replace wear parts according to operation hours and slurry abrasiveness.
● Monitor coil temperature and set automated shutdown thresholds to prevent overheating.
Q: What is the minimum particle size the unit can separate?
A: Typical separation for standard models is 20–50 µm. High‑field precision models can separate finer particles. Recommend lab or onsite trials for confirmation.
Q: How is coil overheating prevented?
A: Options include forced water or oil cooling, temperature sensors with automatic shutdown, and adjusting duty cycle/current.
Q: Can this be used in food or pharmaceutical applications?
A: Yes. Use food‑grade SS316 polished liners, sanitary fittings, and request material certificates for compliance.
Q: How often is maintenance required?
A: Weekly inspections and monthly electrical/cooling checks are typical. Replace wear parts based on running hours and slurry abrasiveness.
