MAGNETS FOR WASTE AND RECYCLING FACILITIES

The recovery of metal from waste materials is extremely important for the recycling industry.

The filtering out and extraction of metals has 3 main purposes –

  1. Resource Recovery – Metals can be reused. They are often remelted and reshaped into new products.
  2. Product Purification – Waste products such as timber and glass are more suitable for recycling after tramp metal has been removed.
  3. Plant Protection – Tramp metal can cause damage to expensive recycling equipment if not removed (e.g. plastic granulators).

METAL SEPARATION EQUIPMENT

Metal separation equipment such as Eddy Current Separators, Overbelt/Suspension Magnets, and Pulley Magnets are used in recycling and waste facilities to extract metal pieces from the products.

Commonly extracted metals include:

Often a number of separators are installed in various strategic locations around a plant. This ensures that both types of metals are removed and the risk of metal contamination is minimized.

Overbelt and Suspension Magnets are installed above belt conveyors to magnetically lift ferrous metal pieces out of the product stream. Contaminants are held against the magnet until cleaned (manual and self-cleaning designs are available).

Magnetic Head Pulleys operate at the discharge of belt conveyors. As waste is dropped off the end of the belt, the metal that may be on the belt, under the burden of material, is held by the magnetic energy of the pulley and dragged around by the belt underneath the conveyors and dropped off into another bin. Magnetic Head Pulleys are ideal as a secondary complimentary magnet downstream of overbelt/suspension magnets.

MSA can provide new magnetic head pulleys or can transform your existing head pulleys to a highly magnetic pulley using MSA’s patented magnetic lagging system.

Eddy Current Separators are essential in material recycling facilities and other general dry waste processing plants. They are used for the removal of non-ferrous metals from dry waste streams. They are typically part of the final stage of the process, removing the non-ferrous materials from the remaining plastics and small fragments of paper/cardboard.

It is critical when dealing with unsorted recyclables to utilize magnetic screening upstream from the Eddy Current Separator (ECS). The ECS, unless it has an incorporated Drum Magnet, cannot remove ferrous materials. It is ideal to have magnetic screening upstream from the ECS to reduce load and wear and tear on the ECS.

RECYCLING AND WASTE APPLICATIONS

Magnetic separators are often used to filter out metal pieces from waste applications such as –

EPA GRANTS

The Australian Government has committed to working with the Environment Protection Authority (EPA) over 9 years to assist in maintaining a clean environment and reducing landfill. Funding has been made available, through grants, to all sectors of the recycling industry to help improve best practice systems.

This includes funding for waste and resource recovery initiatives, such as improved recycling facilities. New and improved recycling infrastructure and equipment will allow waste processors to develop more innovative and efficient methods for processing materials.

A key target of the EPA is to increase the amount of waste processed and decrease the amount of waste sent to landfill by 75%. The EPA is aiming to increase the reuse, recycling, and reprocessing of materials such as timber, cardboard/paper, plastics, and packaging. Processed waste must therefore be high quality and free of any contaminants, such as metal pieces, that will have a negative effect on the recycling process and potentially damage plant equipment.

Between 2017-21, the NSW EPA initiative, ‘Waste Less Recycle More’ has allocated a total of $48 million to improving recycling infrastructure. Similarly, the Victorian Sustainability Fund has allocated $30.4 million to waste and resource recovery.

Magnets and Eddy Current Separators are critical components in any resource recovery application. Improvements to ferrous and non-ferrous metals sorting lines are able to be considered for partial funding under these current EPA grants.

WASTE INITIATIVES

Waste Initiatives have partnered with MSA to assist recycling companies’ with collecting unwanted tramp iron and metal pieces from their waste product lines.

Based in Singleton NSW, Waste Initiatives are leading suppliers of quality recycling solutions including balers, shredders, and compactors. They are also approved resellers of MSA equipment.

Magnetic separators are available direct through MSA, or from Waste Initiatives.

MSA Magnetics offers full-service support to all Waste Initiatives Magnet customers, so no matter who you decide to buy MSA products through you are covered!
