With more than 80 years’ trading experience, the Germany-based Ventur Group focuses on future industries such as environmental technology and wind energy. Its product range covers various serial products made of precast concrete parts, high-tech facades, and large prestressed concrete tanks.
Since 2010, the company’s focus has been on producing and assembling concrete hybrid towers for wind power plants with an in-house developed construction system: high-tapered wall elements are cast in open formworks and then securely interlocked in a building block principle.
Ventur Group has now upgraded its business location in Siegen, North Rhine-Westphalia, with the highly advanced concrete mixing technology supplied by SBM. A super mobile EUROMIX 3300 SPACE plant was delivered in May 2020 and put into operation only two weeks later despite the coronavirus pandemic. The firm’s new SBM concrete mixing plant will produce special concretes especially for innovative wind turbine towers constructed in post-tensioned precast.
To meet the specific demands of the Ventur Group, the EUROMIX 3300 SPACE was equipped with a 3.33m³ twin shaft mixer of the company BHS Sonthofen with double mixing tools to produce special concretes such as HPC (high-performance concrete) and UHPC (ultra-high-performance concrete).
Production speed and capacity for HPC/UHPC can be significantly increased on Ventur Group’s EUROMIX 3300 SPACE model.
The mixer and all aggregate chambers are equipped with sensors to measure the moisture. The temperatures of all ingredients (sand, gravel, cement, water) are measured by temperature probes; a Sauter control regulates the concrete temperature. An integrated high-pressure cleaning system ensures cleaning of the mixer.
Ventur Group’s new SBM plant can be equipped with a bucket conveyor to transport fresh concrete from the mixer discharge hopper to where the fresh concrete is processed to prefabricated parts. SBM says that the sophisticated technology, profitable operation, and the excellent performance ensured by the EUROMIX plant can now be seen at Ventur every day.
“Due to SBM’s mobile plant system, we were able to fully replace an already existing old mixing plant and to bring it right up to date in a very short time. The fully-fledged equipment of the plant allows us to use it independently from the already existing infrastructure,” explains Christian Drössler, managing director of Benno Drössler (Ventur Group).
