Eriez equipment is revolutionising ferrous contamination removal across diverse waste streams.
Ferrous metals, primarily iron and its alloys, can be a large component of numerous waste streams, including municipal solid waste (MSW), construction and demolition debris, industrial by-products, and end-of-life vehicles.
Recovering ferrous materials not only reduces landfill waste but minimises environmental impact by decreasing the need for mining and processing new materials, ultimately promoting sustainability.
However ferrous material contamination poses several challenges for recycling and resource recovery facilities.
Metal can cause significant damage to shredders, conveyors, screens, and other downstream processing equipment, leading to costly repairs and downtime.
Contaminants can also impact the quality of recovered materials such as plastics, glass, and aggregates, impeding their recyclability and market value, not to mention the safety hazards posed by sharp or large ferrous objects to personnel working in waste processing facilities.
Eriez, a global leader in separation technologies, offers a broad portfolio of ferrous metal recovery and sorting equipment tailored to the specific needs of various industries and waste streams.
In material recovery facilities (MRFs), Eriez separators play a crucial role in extracting ferrous metals from commingled household waste and mixed streams of paper, plastic, and other recyclables.
Removing ferrous contaminants such as bottle caps ensures the production of high-quality recycled glass for new containers and other applications.
Ferrous contamination in polyethylene terephthalate (PET) recycling streams can lead to discoloration and defects in the final product. Eriez equipment ensures the removal of these contaminants, enhancing the quality of recycled PET.
While e-waste contains a complex mix of metals, Eriez equipment can separate ferrous components, facilitating further processing and recovery of valuable materials.
Eriez’ metal recovery and sorting equipment uses permanent magnets and electromagnets to sort, separate and retrieve metals.
The Dynamic Pulley Separator uses a rare earth permanent magnetic pulley rotating at an offset speed causing an agitating magnetic field. The combination of this powerful magnetic field with the agitating action allows entrapped steel and weakly magnetic material to be freed from nonferrous materials.
The innovative PokerSort helps alleviate issues caused by long rod-like pieces typically over 61 centimetres in length, commonly referred to as pokers, that can damage downstream equipment.
Using a special magnetic drum positioned at the end of the shredder discharge belt, the PokerSort separates pokers as they catapult off the end of the belt with a different trajectory than the rest of the shredded material or “frag.”
Using design software and unique magnetic circuits, Eriez provides permanent and electromagnetic scrap drums with deeper magnetic fields to reclaim ferrous materials in materials.
Such materials can be found in recovery facilities, municipal solid waste, scrap metal yards, wood waste, slag, incinerator bottom ash, foundry sand and minerals processing applications.
The suspended electromagnet provides tramp metal collection from conveyed materials. The electromagnet is typically mounted or suspended over a conveyor belt to remove large pieces of metal that represent a hazard to downstream crushers, mills, pulverisers and grinders. By tackling the challenges posed by ferrous contamination, Eriez equipment plays a vital role in maximising the value of secondary resources and minimising environmental impact.
