Reference screening machines for electronic scrap
This recycling project at Immark shows the decisive influence that precise classification, fine fraction screening and material feeding have on the quality of the end product in electronic scrap processing.
The SPALECK screening and conveying technology used prepares the electronic scrap in such a way that downstream sorting systems can process the sorted fractions very efficiently.
Switzerland is home to one of the world’s most modern processing plants for electronic scrap, with a focus on high material purity and maximum efficiency and Efficiency.

Electronic waste is a highly complex material stream with widely varying material properties. Different device classes, designs and material composites must be reliably recycled – from circuit boards and cables to housing parts and metal composites.
After shredding, a mixture with different Particle sizes and material densities is produced that is challenging in terms of process engineering. Typical components are non-ferrous metals, plastic-containing fractions, circuit board parts, cable and wire remnants as well as a mix of fines consisting of glass, sand and impurities that should not be underestimated.
Without targeted classification and separation of fines, this leads to specific problems in the further Recycling process:
For Immark, the focus was on processing the shredded material using screening machines so that the sorting devices could sort it under optimal conditions. The aim was to produce clearly defined fractions from the very heterogeneous WEEE material flow and to prevent impurities such as dirt or long parts.
The video shows how Immark and SPALECK worked together from project development, through extensive screening tests in the SPALECK TestCenter, to the optimal solution for e-waste processing.

TRANSFERABILITY for your preparation
Immark’s project shows how strongly the quality of sorting depends on the upstream material preparation.
In metal recycling and WEEE recycling in particular, the combination of classification (Screening process), targeted separation of fine particles and defined material feed determines how efficiently and reliably the sorting technology used can detect the recycling material and sort it into its individual components.
Extensive screening tests in the SPALECK TestCenter enabled the optimum Machine configurations to be determined and validated in advance.
The recycling technology used is transferable to applications in which heterogeneous material flows are prepared for eddy current and sensor-based sorting:

No, processing electronic scrap and metals such as SLF or ASR is no problem for SPALECK Screening technology. Our screening machines are configured to reliably handle different Material flows and similar applications. We determine the exact machine setting with you in advance.
The screening machine is designed to fit perfectly into your planned electronic waste processing plant. SPALECK screening machines are customized to your material, throughput, and process control. We take into account interfaces, installation conditions, and conveyor systems to ensure easy integration into your plant. It also happens that plant operators replace screening machines from other manufacturers with SPALECK screening machines in an existing facility. This is generally not a problem either.
Yes, you can test your electronic scrap in advance on SPALECK screening machines. In the SPALECK TestCenter, we carry out tests with your original material on two complete Recycling lines and thus analyze under real conditions which Separation sizes and screening machine design is optimal for your application. This provides you with a reliable basis and you can also use the screened material for further tests, e.g. with sorting machines. The tests in the SPALECK TestCenter are free of charge for you.
SPALECK Screening technology improves sorting performance in Electronic Waste recycling by Classifying (i.e. Screening) the Material flow into defined Particle sizes and removing interfering fines. This produces clearly defined fractions with a specific particle size from an unscreened mixture with a wide range of particle sizes. The equally sized parts are then separated by material using sorting equipment. The same size helps the sorting technology to better detect the individual components.
Fines must be removed from electronic scrap because they significantly impair the performance of the sorting technology used. The materials in the fines (e.g. sand, dirt, impurities) cause contamination in the sorting equipment, accumulate on larger parts and lead to incorrect rejections during electromagnetic, X-ray or sensor-based sorting. With the right Screening technology, the fines are reliably removed. A typical screening size here is 0 – 8 mm Particle size, which is screened off as fines.
The following materials, among others, are processed during Electronic waste recycling:
– Ferrous and non-ferrous metals
– Plastics
– Printed circuit boards and circuit boards
– Glass components
– Fine fractions from shredded composite materials
– Sand, dust and impurities
All of these materials must be specifically separated and processed in the Recycling process.
Classification, i.e. the screening process according to material size, is important in Electronic waste recycling because it separates the material stream into defined particle sizes. Modern sorting equipment can only clearly identify the materials and separate them precisely according to material components if the grain bands are uniform.
WEEE recycling is the processing of waste electrical and electronic equipment to recover recyclable materials such as ferrous and non-ferrous metals, plastics and circuit board components. The appliances are shredded, the shredded material is classified (screened) by size and then sorted mechanically and by material type using sensors.
