The economic and efficient recovery of clean metals such as scrap iron, aluminum, stainless steel (VA), copper, brass, zinc and metal alloys is the focus of scrap metal processing.
Screening machines from SPALECK help you to classify the input material according to size. You benefit from our 3D screen linings, for example. They keep your target fraction free of unwanted long parts.
We also tailor our screening machines, ActiveFeed feed hoppers and conveyor chutes optimally to your recycling process, the shredding and sorting technology used and the special requirements of your material.

In practice, a distinction is usually made between light (3-6 mm thick) and heavy shear scrap (over 6 mm thick) – so-called E1 and E3 steel scrap in defined dimensions. There are also various other types of steel scrap. Typical raw materials include pipes, crash barriers, sheet piling, sheet steel and railroad tracks. But industrial waste, scrap steel, reinforcement iron and industrial and heating systems are also included.
Shredder scrap, also known in practice as shredder steel scrap(E40), is obtained by shredding metals and their compounds using magnetic separation (magnetic drums). Shredder steel scrap is magnetic ferrous scrap with a defined bulk density and dimensions. After the magnetic steel scrap has been recovered, the shredder heavy fraction containing aluminum, copper, stainless steel, metallic composites and other metals remains for further processing. Both the heavy and shredder light fractions also contain a mixture of plastics, wood, glass, rubber and other non-ferrous metals.
Recycling aluminum scrap involves the recovery and reuse of clean old aluminum.
Aluminum scrap consists, for example, of aluminum sheets, stamped aluminum remnants, profiles, aluminum castings from automotive recycling, or even car rims or industrial waste such as chips or aluminum foil.
In practice, a distinction is made between post-production and post-consumer aluminum, depending on the “originator”. The latter includes, for example, aluminum cans or aluminum lids from food packaging.
When end-of-life vehicles are shredded, the airworthy light fraction, also known as shredder light fraction or SLF, is often extracted first. The steel and ferrous materials are then separated using magnetic technology. The material that remains after air separation and FE separation is referred to as shredder heavy fraction (SSF or SHF). In North America, the light fraction is usually separated from the magnetic iron fraction after shredding using so-called Z-boxes.
WEEE or electronic waste refers to electrical and electronic appliances and old electrical appliances that are sent for recycling.
The aim is to process old appliances in such a way that the individual components made of metals such as copper, aluminum, precious metals, plastics, circuit boards, etc. can be recycled by type as far as possible. The processes for processing and recovering the various categories of old appliances (refrigerators, small household appliances, monitors, etc.) are specialized and require sophisticated screening and sorting technology in order to obtain unmixed products.
The energy recovery of household waste produces bottom ash, so-called IBA, in the waste incineration plant (WIP). On average, this makes up around 30 % of the input of a waste incineration plant and contains around 90 % minerals, followed by up to 8 % ferrous metals and around 2-3 % non-ferrous metals. The non-ferrous metals also contain interesting proportions of precious metals, which are contained in very specific grain sizes and fractions. Due to the residual moisture content of the material, optimum screening technology and feeding is only something for specialists like SPALECK.

Sand, dirt, impurities or excessively large parts not only increase material wear during shredding, but also pose a direct risk of costly repairs.
Protect your valuable shredding and sorting technology with the right screen cut.
Are your sorting machines really performing as well as they could? Or are the sorting belts under- or overloaded? And do your conveyor troughs enable optimum mono-layer material feed? We would be happy to tell you how you can protect your technology and maximize your yield with 1A screen quality and material feed.
Increasing demands on material qualities, green steel, new markets & competitors and many more factors… With the right technology, you can prepare for this with peace of mind. SPALECK offers you modern screening technology that can also be easily adapted later in the existing machine.
