Success stories

Twin-shaft batch mixer used for construction of Tesla Gigafactory in Grünheide

On Germany's most impressive construction site in Grünheide, Brandenburg, the US company Tesla is building its latest gigafactory for electric cars. The project worth several billion euros is to be completed in record time, with the first electric cars rolling off the assembly line as early as summer 2021. The construction of this gigantic factory requires huge amounts of concrete. To guarantee the required quantity, the plant operators involved also rely on high-performance mixers from BHS-Sonthofen. But what if a spare part is needed for these mixers? Every second counts in a case like this.

Twin-shaft batch mixers for Vietnam’s first offshore windfarm project

Bac Liêu Province Wind Power Plant in Vietnam is Asia’s first large-scale coastal wind energy project. Operating since 2013, it is being expanded continuously. During the current third expansion phase, 71 turbines are being constructed. The challenge of this project can literally be found at the bottom of the sea: the cement bases for the wind turbines cannot simply be produced on land and then placed in the ocean. Instead, they have to be poured directly into the ground, using a floating platform. To this end, a mobile batching plant was installed on a dredge. At its heart are two twin-shaft batch mixers from BHS.

All-in for quality and reliability: Grange Quarry relies on twin-shaft batch mixer from BHS-Sonthofen for Crossdykes Windfarm turbine bases

In a very rural and isolated area near Eskaldemuir in Scotland, Grange Quarry Ltd is supplying concrete for a ten-turbine windfarm on behalf of a Scottish energy provider. The mobile plant for this task is provided by RSD Concrete. The challenge: Grange Quarry required large quantities of concrete in a very short time for the concrete bases. To ensure pour speed and a quick turnaround, Grange Quarry relied on a twin-shaft batch mixer from BHS-Sonthofen.

DKXS mixes concrete for tunnel segments of the Grand Paris Express

It is Europe’s largest public transportation and infrastructure project: The construction of the Grand Paris Express lines. Approximately 75 percent of the new 200-kilometers-long track will be running underground. In a new concrete plant built by EMCI, a DKXS 3.0 is mixing fiber concrete for the tunnel segments.

Producing concrete for a 700,000 square meter long dam

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.

On the fast track: BHS installs twin-shaft batch mixers in only 2.5 days

When plant manufacturer Tublorom was urgently looking for a replacement for a defect mixer of its customer Arcada at the Galati site in Romania, BHS-Sonthofen delivered the required machine in the shortest time possible. A total of just twelve days passed from the initial inquiry to the resumption of concrete production. Of this total, BHS needed only two and a half days for the complete installation of the twin-shaft batch mixer type DKXS 1.67.

Concrete for Europe's biggest wind farm

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.

Mixer has been running for 24 years

Over the years, BHS’ customer CPAC (The Concrete Products and Aggregate Co., Ltd.) in Thailand has purchased a great number of BHS mixers - and one of them has been running for almost a quarter of a century. The mixer is still working to full efficiency. CPAC is very satisfied with the performance of this recently inspected twin-shaft batch mixer from BHS.

The right mix for the Aberdeen port expansion

Dragados UK & Ireland uses mixing technology from BHS-Sonthofen to produce the concrete required for the expansion of the Aberdeen harbor. A total of 9,000 accropods will be produced with the concrete and used in the outer protective walls for the northern and southern breakwaters. Industrias Leblan supplied a mixing plant that includes a BHS twin-shaft batch mixer.

Largest mixer in the corporate history of BHS

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.

The finishing touch for concrete sands: Stevin Rock relies on rotor centrifugal crushers from BHS-Sonthofen

25. September 2019
The sand found in the high-strength concrete used to construct Dubai and Abu Dhabi’s prestigious buildings must be pure and the particle shape needs to be cubical. Since the large quantities of natural sand in the region do not boast these properties, mine operator Stevin Rock manufactures the sought-after commodity out of limestone itself in UAE. Two rotor centrifugal crushers of type RSMX from BHS-Sonthofen have been used for the final – and crucial – finishing step since September 2018. The two RSMX crushers with TwinDrive break the particles down into the ideal shape, ensuring a consistently high sand quality
