Case Study: Electrical Waste Recycling Group

Huddersfield-based Electrical Waste Recycling Group (EWRG) has been in operation since 2008.

Its recycling plant incorporates shredding and recycling equipment for the recovery of materials from electrical and electronic waste.

As part of this process, ferrous metal is removed with overband magnets, then the product is presented to an eddy current separator (ECS) for non-ferrous metal recovery.

Although the overband magnets at the plant were removing the majority of ferrous metal, some remained which was damaging EWRG’s existing ECS belt and rotor cover.

EWRG consulted Magnapower to assist with this ferrous protection issue. After a site survey, it was determined that a magnetic head pulley in the conveyor preceding the ECS of any remaining ferrous metal after the overband magnet.

This modification has significantly extended the life of the ECS belt and rotor cover, and also produces a less non-ferrous end fraction.

Shaun Donaghey, EWRG group operations director, says: “It was crucial for us to protect our process and improve our separation quality. EWRG has the only approved UK mechanical treatment for flat panel displays (pictured), so it was essential for us to achieve the highest recovery rates.

“The inclusion of the head magnet not only gave an additional protection to the ECS and the improved longevity of the cover and belt, but also improved our overall recovery rates. We now have a throughput of over 700 flat panel units per hour and achieve a 98.7% recovery rate. All our recyclate is clean stream and placed in the UK supply chain.”
