Sorting – Being magnetic, iron is easily separated from other recyclable metals using powerful magnetic belts.
Shredding – Shredders used by R Davies have rotating magnetic drums that extract iron and steel from any mixture of metals.
Media Separation – The next step involves electrical currents, high-pressure air flows, as well as liquid floating systems. This process removes any protective layers (like on drinks cans).
Shearing – Here, hydraulic machinery is used, creating pressures high enough to cut the thickest, heaviest pieces of iron. For example, railway lines and parts of old ships. Other cutting techniques are also used, including equipment using plasma arcs. This new type of waste treatment system involves heating metal waste to super-high temperatures. This produces gas that can be burned for energy together with solid waste, which can be used as a building material.
Baling – This process produces large blocks of iron, which makes them far easier to move and transport.
