Material Conveying
Spent sand or granular material containing ferrous contaminants is fed uniformly into the inlet zone via belt conveyor, vibratory feeder, or chute.

Ultra-High Magnetic Field
High-energy NdFeB magnets with flux-concentrating design—surface field ≥8,000 Gauss, captures small ferrous particles (≥2mm).

Zero Energy Consumption, Maintenance-Free
Pure permanent magnet design—no power, no excitation, no motor, no heat—service life ≥10 years.

High Separation Efficiency, Stable Operation
Iron removal rate >99.5%, handles 10–150 t/h, suitable for 7×24 continuous operation.

Compact Structure, Flexible Installation
Modular design allows inclined mounting at conveyor head, in-line horizontal integration, or overhead suspension.

Heat & Wear Resistant
Belt made of food-grade polyurethane or rubber, heat-resistant up to 80°C; housing and rollers in stainless steel (304/316)—corrosion-resistant and easy to clean.

Smart Monitoring (Optional)
Optional iron buildup sensor + alarm + PLC output for remote monitoring and interlock shutdown

Continuous iron removal on conveyor belts to protect crushers, screens

Purification of reclaimed sand, quartz sand, and foundry raw sand

Iron removal in raw materials for building materials, glass, ceramics

Integrated with S56L reclaimer, cooler, elevator for full automation
