Lithium-Ion Batteries Safely Recycled Using a New Process

17. September 2020
The recycling of lithium-ion batteries increasingly involves major challenges. BHS-Sonthofen has developed a new process through various research projects, which is being used for the first time in Scandinavia: A completely gas-tight process reliably prevents fires and the escape of toxic gases.

BHS-Sonthofen’s mixing technology used to modernize the Afsluitdijk in the Netherlands

01. September 2020
The Netherlands is protected from flooding by a 32 km long dam: the Afsluitsdijk. This impressive structure – the total area of which is around 700,000 square meters – is in the process of being completely modernized and expanded. For this purpose, innovative concrete blocks from Holcim Coastal B.V. are being used. To ensure the blocks are of an equally high quality, they opted for strong partners in terms of mixing technology and plant engineering: BHS-Sonthofen and Loke BV. BHS is delivering the mixer for the expansion of the production facility in Alphen aan den Rijn, where the concrete for the project is to be mixed. Loke BV took over the construction of the plant.

New process from BHS avoids hazards in recycling of lithium-ion batteries

02. July 2020
While the relevance of batteries and accumulators as storage media is increasing significantly, their recycling is linked to challenges. BHS-Sonthofen has developed a safe process for the recycling of batteries and accumulators in several research projects. A continuous gas-tight process from the shredder to the dryer, where the electrolytes evaporate, reliably prevents fires and the escape of toxic gases.

Concrete for Europe’s biggest wind farm

16. June 2020
Mixing concrete for more than 1100 windmills of Europe’s biggest wind farm is no small task. Which is why Tecwill Oy, a Finnish expert for concrete batching plants, puts his trust in a twin-shaft batch mixer from BHS-Sonthofen. The mixer produces four cubic meters of fiber concrete per batch and allows for casting up to three windmill bases per day. Tecwill and his customer particularly praise the mixer for its reliability and the efficiency of the time- and cost-saving mixing principle.

Less wear for economically efficient processing of ASR

19. May 2020
A BHS-Sonthofen rotor impact mill (type RPMX) has been in operation at Jansen Shredder Recycling BV in Moerdijk, the Netherlands, for the fine processing of automotive shredder residues (ASR) for almost a year. Thanks to years of experience in the processing of metal-bearing waste materials, the experts from Sonthofen found the optimal machine for processing abrasive materials. Wear costs at Jansen have significantly decreased since.

The right mix for the new Aberdeen South Harbour

15. May 2020
Dragados UK & Ireland, a construction branch of the Spanish ACS Group, is using mixing technology from BHS-Sonthofen to produce concrete in the £350 million expansion of Aberdeen Harbour in Scotland. A total of approximately 9,000 accropodes are manufactured with the concrete and used as the outer armour for the north and south breakwaters. To this end, Industrias Leblan provided Dragados with a mixing unit including a BHS twin-shaft batch mixer.

Largest mixer in the corporate history of BHS

01. April 2020
After winning an international tender, BHS-Sonthofen was commissioned with constructing the largest mixer in the company’s history. An Indian zinc mine operator required a mixer with a very large filling capacity. The proven Combimix system with overflow was custom-built by BHS-Sonthofen in this extraordinary size and shipped off to India. Ease of maintenance, implementation of all customer requirements and a local service office convinced the Indian customer to opt for BHS-Sonthofen.
