Preparation

Preparation of raw samples or samples that are not ready for analysis:

We are able to process raw samples of up to several 100 kg in our company. In order to obtain homogeneous chips and fine powders with a grain size of less than 160 μm, the treatment steps include preparation:

• Drying (moist sample goods up to several 100 kg)
• Shredding (hammer mill and shredder for pre-shredding e-scrap)
• Crushing (jaw crushers of various sizes for brittle materials up to several 100 kg sample size)
• Sample division
• Incineration (pyrolysis process in 2 TÜV-certified and environmentally friendly incineration furnaces up to 200 kg per day). The plant includes post-combustion, A-carbon and particle filters to comply with TA-Luft.
• Sieving (sieving plants of various sizes)
• Melting
  • Induction melting furnaces from 5 to 25 kg
• Machining of ductile metals
• brittle materials are ground as after stoning, finely ground
• Grinding (various grinding systems for different materials, e.g. ball mills, disc mills, vibrating disc mills): Ball mills, disc mills, vibrating disc mills)
• Mixing (wobble mixers from approx. 1 to 50 kg and screw mixers)
• Laboratory sample divider

We crush, melt, grind, sieve, divide to homogenise small (a few grams) to larger (several 100 kg) raw samples to produce exact average samples for precise laboratory analysis.

Sampling:

We carry out sampling and sample testing at home and abroad, whereby appropriately qualified specialist colleagues (sworn experts) are commissioned as subcontractors.

Development:

We carry out appropriate test series to optimise existing operating processes or to develop new separation and recycling processes. We are constantly modifying our methods in line with the latest specifications and legislation. We take a sustainable and environmentally friendly approach to all our activities.
