Core Equipment & Technology Pathways

Hengji provides a specialized portfolio of magnetic separation equipment, engineered for the unique demands of the magnetic separation recycling industry. Our targeted technology pathways ensure maximum efficiency in recovering valuable materials from complex waste streams, a critical step in the magnetic separation of solid waste.

1. Permanent Magnetic Drum Separators

Acting as the conveyor’s drive pulley, these robust units automatically extract ferrous metals like iron and steel from mixed material flows. They are ideal for primary separation, offering maintenance-free operation, high energy efficiency, and easy installation. This technology is fundamental for the rapid recovery of bulk ferrous metals from municipal and industrial solid waste.

2. Tailings Recovery Machines

Designed for slurry-based processes, these machines efficiently recover fine magnetic materials from tailings. Their high-intensity magnetic disks extract minerals from the slurry, achieving recovery rates up to 95%. This solution is vital for maximizing resource yield in mineral processing and recycling applications, promoting water and energy savings.

3. Eddy Current Separators

This key technology enables the recovery of non-ferrous metals. It generates a high-frequency magnetic field that induces eddy currents in conductive materials like aluminum and copper, ejecting them from the waste stream. This process is essential for separating valuable non-ferrous metals from inert materials such as plastics and glass, completing the material recovery cycle.

Specific Application Scenarios & Target Materials

Hengji’s magnetic separation equipment delivers targeted solutions for resource recovery across multiple industries, demonstrating crucial effectiveness in magnetic separation of solid waste and industrial by-products.

Metallurgical & Mining Tailings Reprocessing

Our technology is extensively applied in reprocessing waste streams from iron ore, non-ferrous metal mines, and gold concentrators. These materials, typically stored in tailings ponds or managed as slurry streams, contain valuable residual magnetic minerals such as magnetite and ilmenite.

The primary objective is to recover these valuable elements from discarded tailings, effectively transforming industrial waste into profitable resources. This application represents a sophisticated form of magnetic separation recycling that significantly enhances overall resource utilization rates while addressing critical environmental challenges.

This approach directly mitigates environmental risks associated with tailings accumulation, reduces land occupation, and converts potential pollutants into valuable commodities. Our disc-type tailing recovery machines have proven particularly effective in this field, achieving high recovery rates while operating efficiently in challenging slurry environments. This technology enables mining operations to implement more sustainable practices while improving their economic performance through comprehensive material recovery.

Industrial Solid Waste & Scrap Recycling

Hengji’s equipment delivers efficient magnetic separation of solid waste across numerous industrial recycling applications, transforming complex waste streams into valuable resources.

In Electronic Waste (WEEE) Processing, our permanent magnet drums and eddy current separators work in tandem within dismantling lines. They systematically recover ferrous metals, copper, and aluminum from shredded appliances, a critical step in advanced magnetic separation recycling.

Municipal Solid Waste Sorting & Recovery

Hengji’s technology is integral to modern magnetic separation of solid waste in municipal treatment plants and material-specific recycling lines. Our systems are deployed in facilities processing mixed municipal waste, used plastics, and tires to recover valuable metals and purify material streams.

This application of magnetic separation recycling utilizes both permanent magnets and eddy current separators working in sequence. They effectively separate steel and aluminum cans from the waste stream while simultaneously removing metallic contaminants from crushed glass, plastics, and wood. This process significantly enhances the purity and market value of recycled materials, ensuring higher quality feedstock for regeneration lines and supporting circular economy goals in urban waste management.
