Why Eriez products are a force to be reckoned with, across the recycling industry.
Electronic waste in Australia is growing rapidly, expanding up to three times faster than general municipal waste, according to the Victorian Environment Protection Authority.
Projections indicate a potential increase of nearly 30 per cent by 2030.
While environmental agencies and governments across Australia are working to reduce e-waste, their composition – including valuable resources such as gold and copper, hazardous substances, and plastics – means they can be difficult to recycle.
Magnets can play a crucial role, enabling the separation of ferrous metals such as iron and steel from other components; essentially acting as a primary sorting mechanism to isolate magnetic materials from non-magnetic ones such as plastics and aluminium.
Eriez, a global leader in separation technologies, has positioned itself as a driving market force, providing solutions across a range of industries including recycling, packaging, aggregate, mining and food.
Among its innovations are suspended magnets, both permanent and electromagnetic, designed to tackle the tough challenges of the recycling industry.
Typically mounted or suspended over conveyor belts, electromagnets remove large pieces of metal that can damage or tear expensive conveyor belts or downstream equipment such as crushers, mills, pulverisers and grinders.
The strength of the magnet also improves product purity for recyclers. Eriez has 23 magnet sizes, 69 standard models and has customised hundreds of special designs for unique applications.
Suspended electromagnets are available in manual cleaning or self-cleaning models. Self-cleaning models have a short belt conveyor built around the magnet to allow automatic removal of metal from the magnet face.
Suspended permanent magnets require no power and have proven to be most effective for the removal of metals from material on fast moving conveyor belts, including removing nails and screws from waste wood and recovering steel cans from municipal solid waste.
Suitable for separation of wet or dry, as well as fine or coarse materials in large or small tonnages, they can be fitted to mobile crushing, screening and shredding machines. The uniquely designed magnetic circuit is long and flat, providing a greater area of magnetic coverage with a maximum depth of field, also with less head room required, thanks to the electromagnet.
Operating advantages include eliminating the possibility of accidental shutdown and shutdown due to power failure, which means the magnet strength never varies.
Features include 200-400-millimetre suspension heights, multiple magnet circuit designs, hydraulic and electric motor options, and a range of sensors available to suit 500-2000-millimetre-wide conveyors as standard, with larger units available upon request.
Two models and configurations are available – CP permanent magnets and TP permanent magnets. CP magnets use a permanent magnet circuit to provide a continuous and uniform magnetic field across the feed belt to optimise separation of metal.
The magnet is placed across the conveyor belt. A moving continuous belt surrounds the magnet box. Ferrous material is attracted by the magnet and is held on the belt. As the belt moves clear of the magnetic field, ferrous metals fall away into bins for collection and disposal.
The TP magnets incorporate a higher strength, dual pole magnet design to offer improved separation of smaller metal.
Self-cleaning models are available in a variety of sizes to meet installation requirements, while manual cleaning models are lightweight and suitable for confined installations.
