Magnetics aids bottle separation

Turnkey project engineering company GAME Engineering has installed an Eriez magnetic separation system to facilitate the separation of cans from plastic bottle waste at Materials Recovery's recycling plant in Skegness, Lincolnshire.

The objective was to provide 95% separation for both steel (ferrous) and aluminium (non-ferrous) cans at a throughput of 133m3 per hour. Eriez offered a solution which incorporated a suspended permanent magnet, model CP 20/120 SC2, for achieving 95% purity on separation of ferrous cans and an LC 4009 model eddy current separator (ECS) with 1000 mm feed width for achieving matching purity levels on separation of aluminium cans.

The suspended permanent magnet model installed by GAME Engineering is for positioning across the conveyor belt and self-cleaning. This means the belt around the magnet box is moving continuously so that ferrous materials attracted to the magnet fall away into a collection bin once clear of the magnetic field.

The LC ECS unit is a low-cost, robust ECS, which operates well in separating larger non-ferrous metals in tough working environments.
