Innovative recycling process for lithium-ion batteries

After the batteries have been discharged, they are shredded with the BHS Rotary Shear (VR) for packs and modules or the Universal Shredder (NGU) for cells or as a second shredding step after the rotary shear. In order to avoid sparking, the shredder for this special application is designed gas-tight and operates under a protective atmosphere.

As soon as the feed material has reached the desired target size, the parts fall through appropriately designed grate segments. In horizontal continuous or batch dryers of our subsidiary AVA, the shredded batteries are then heated batch by batch so that the electrolyte components evaporate and can be recovered via a condensation unit. The solid components, completely free of electrolytes, undergo a dry-mechanical treatment. After an initial screening, black mass can already be recovered. Subsequently, a heavy/light separation takes place by means of sifting. The remaining composites go to a second size reduction stage and are fed to a dry-mechanical sorting system. As end products, the black mass as well as smeltable copper concentrate and concentrated aluminium can be recovered.

Universal shredder

The universal shredder of type NGU is a high-speed single-shaft crusher designed for pre- and post-cutting of any material that can be cut. This includes paper, files, data media, textiles, wood, cables, plastics and packaging. It shreds the feed material to a size between 10 and 120 mm.

Efficiently processing shredder fractions

The BHS rotor impact mill is a high-performance crusher with a vertical shaft that addresses the needs of the recycling industry. The mill’s unique impeller rotor works together with a toothed anvil ring to subject the inserted material to severe mechanical stress. Material compounds are crushed and separated selectively, entangled materials are isolated, and brittle-hard materials are crushed very finely. At the same time, metals are shaped into balls and cleaned. Watch the video to find out how to optimally prepare shredder fractions for separation by disaggregating composite material and pelletizing metals with the RPMX rotor impact mill.

Processing of copper armatures and electric motors

Optimized recovery of copper from motor armatures and electric motors – also known as meatballs – at a customer facility in France thanks to selective shredding using the BHS rotor shredder of type RS 2018. The fed copper armatures and electric motors are first shredded and separated using the RS unit. They can then be separated into pure fractions (e.g., copper, iron, etc.).

Non-ferrous metals in incinerator bottom ash (IBA) are turned into valuable resources

BHS-Sonthofen planned and implemented a turnkey plant for the processing and refinement of metals derived from incinerator bottom ash and other metal-bearing fractions. BHS recycling machines are core components of both processing lines, as they allow for efficient shredding.

BHS Biogrinder crushes and mashes organic domestic waste

The BHS Biogrinder (type RBG) is used in the processing of biomass for biogas generation. The BHS Biogrinder is in use in southern Germany to crush and mash organic domestic waste. The upstream substrate processing speeds up gas production in the fermenter. Overall, the biogas plant operates more efficiently and reliably.
