Resource Efficiency New Separating Plant for Non-Ferrous Metals
Erdwich-Zerkleinerungs-Systeme GmbH, a specialist in the field of recycling and reuse of valuable materials, has recently developed a classifier plant for non-ferrous metals which separates heavy from light materials. The aim is the complete recovery of valuable materials.
In times of climate crisis, environmental protection and resource shortages, recycling is becoming increasingly important. The recycling of ferrous (FE) and non-ferrous (NE) metals is of particular importance in Europe. Germany, for example, can only ensure its economic development by optimizing metal recycling, as stated by the BDSV, the German Association of Steel Recycling and Waste Management Companies. To enable modern and environmentally friendly recycling plants to achieve complete recovery of valuable materials, Erdwich-Zerkleinerungs-Systeme GmbH, a specialist in the field of recycling and reuse of valuable materials, recently developed a separating plant for non-ferrous metals that separates heavy from light materials. Thus an important contribution to the security of raw material supplies and the conservation of resources is made.
"The term separator is generally used to describe a device used to classify solids. By utilizing the different sinking speeds of the various substances in an air stream, these are subdivided and separated according to defined criteria such as particle size, density or inertia," explains Florian Boehm-Feigl, CTO at Erdwich. "One of our projects includes a classifier system for non-ferrous metal granulate". This enables dust, pure granulate, foils, fluff and other light material from non-ferrous metal to be separated. It is important to extract the light material as reliably, easily and above all maintenance-free as possible in order to either further separate the non-ferrous metal or sell it. Special adaptations such as a throughput rate of up to 5 t / h or a wide variety of material mixtures such as aluminum, iron, copper and other non-ferrous metals as well as wood, plastics, fabric or dust make the plant, which can be used for all areas in which heavy and light materials are to be separated, unique on the market. Only the grain size of the metal must not exceed a diameter of 100 mm.
Separating Plant as an Extension of an Existing Large-Scale Plant
In the metal recycling sector, the separating plant, which is 7,146 mm high and between 5,616 mm and 7,461 mm wide - depending on the position of the support elevator - can be used, for example, in combination with an RM 1350 twin-shaft ripper as a pre-shredder for non-ferrous scrap. Six different, automatic program sequences can be monitored and controlled: the control cabinets for the granulator, magnet technology, non-ferrous separation technology and X-ray separation technology as well as the dust filter system and the RM 1350 pre-shredder. The classifier system thus enables the expansion of an existing large-scale plant and is installed directly under the conveyor belt discharge of a screening drum. By classifying various materials such as aluminum, copper or other metallic alloys, the material is dedusted and freed of foreign matter and achieves considerably higher prices in resale.
