JOEST has delivered the smallest TopSpin Double-Deck Cascade Screen ever. In October, JOEST built a TopSpin Screen with a screening area of only 1.2 m² (with a width of 1000 mm and only 1200 mm effective screen length). This screen is used for the pre-separation of metal scrap in the recycling industry. The heavy products which are difficult to screen were separated out beforehand. The problem here was that large pieces clogged the system and excessive dust on the pieces of scrap was a burden for all workers on site. The Double-Deck Screen solved the problem by separating parts with a size of 4 – 80 mm from excessively large or small pieces. The medium sized product could then be further processed without danger in the downstream system. One of the aims of separation is to guarantee longer intervals between cleaning the plant. The screen was modified individually to suit customer requirements and could be fitted into the confined environment with a length of only 2 metres in total. For JOEST, even smaller screens still deliver…

For a world-leading US processor of car recycling, JOEST has produced one of its biggest TOPCILLA flip-flow screens yet for classifying light materials. During car recycling, the JOEST flip-flow screen is used after shredding to classify lightweight materials in preparation for further processing. TOPCILLA combines the advantages of two different screening principles in one machine — the proven JOEST TopSpin cascade screen on the upper deck and the unique Flip-Flow Screen OSCILLA on the lower deck. The upper deck of the TOPCILLA combi-screen is configured as a TopSpin cascade screen with self-cleaning screening surfaces. Each individual screen opening is opened in the conveying direction, similar to a finger screen. Continuous self-cleaning is ensured by an overlap between the screen’s movement and the screening surface. The upper deck performs separation at 35–40 mm and, thanks to the special cascade screen surface, blockages are virtually impossible. The…

JOEST and its American partner are supplying a complete processing system in the USA for the recovery of fine metal with a grain size smaller than 12 mm. JOEST is supplying the screening and separation technology for this patented processing system, including long-part separators, flip-flow screens, air separators and three-way separation tables. The purpose of the system is to recover fine metals and separate light from heavy metals. The feed material consists of the fine fractions of crushed cars without the magnetic portion. These are called “ASR fines” in the USA and “shredder heavy fraction / shredder light faction” in Europe. First of all, long copper cables are separated from this material using the long-part separator. Subsequently the 0–12 mm fraction is screened at approx. 4 mm in the JOEST Flip-Flow Screen TOPCILLA. Each fraction (0–4 and 4–12 mm) goes to one of the four K-Sifters with separation tables. The K-Sifter is installed above…
