SBM MINERAL PROCESSING

Successful technology upgrade at Union-Beton

Stationary mixing systems, in general, last decades. But at some point, everything comes to an end. After a service life of 48 years, the company Union-Beton GmbH & Co. KG – to ensure its market position – needed a new production basis at its Ludwigsburg location in Germany. The company consequently required high-performance, individually designed plant engineering, and that is how Union-Beton and SBM Mineral Processing came together. With its stationary Towermix 3000 + 1670 ST D9 450 V system, the innovation leader in concrete mixing systems from Upper Austria was able to deliver a convincing response to all requirements.

 SBM Mineral is one of a few companies in this sector of industry that, according to its own statement, can claim to be more than just a manufacturer of concrete mixing systems. For the client, Union-Beton, this was not an insignificant point: the advanced Towermix 3000 + 1670 ST D9 450 V system was to be installed on the existing foundation of the old system. The optimal approach here was a complete turnkey concept: from dismantling, the old mixing system to commissioning the Towermix – everything from a single source, was here the optimal approach and one of the core competencies of SBM Mineral Processing.

Year-round sustainable operation

It was also necessary for the new system to meet the requirements of the future: e.g., in terms of sustainability. In a fast-moving working world with its associated changing regulations, the requirements placed on the systems contractor were accordingly strict.  SBM Mineral Processing has more than 40 years of experience in concrete technology, which it focused in a pioneering fashion on the Towermix 3000 + 1670 ST D9 450 V.

Technically speaking, this means for the Towermix at Union-Beton, equipping a system that features high-pressure cleaning as well as integrated video monitoring for the two type BHS DKXS twin-shaft batch mixers that supply 3.00 m³ and 1.67 m³ hardened concrete per batch. This performance capacity, in interaction, achieves a total output of up to 140 m³ per hour. In harmony with contemporary awareness for CO2 balance, an efficient heating and cooling system for aggregate storage and mixing water – and for space heating in the compact tower – ensures year-around sustainable operation that is optimized by enclosed, winterproof insulation cladding. The compact construction of the Towermix D9 series makes it possible to implement, in addition, two extra-wide lanes for truck mixers. Another special demanding detail: installation of a traversable feed hopper with hydraulically operated hopper cover, to improve the logistics of incoming material supply.

Wide ranging offering from Union-Beton

Raw materials supply for the Towermix is ensured by aggregate storage with eight compartments and a total buffer area of 450 m³. The discharge cones, designed with especially steep walls, ensure complete discharge of sluggishly flowing aggregate. Binding agent storage consists of four silos of 2 x 60 tons each, of which two binders are batched and weighed in separate scales for liquid screed production. In a separate batching and weighing unit, up to six admixtures can be directly discharged into the mixer. The comprehensive overall configuration is necessary for mixing the wide-ranging Union-Beton offering of concrete products. The performance profile also includes, in addition to standard concrete, production of architectural concrete, steel fiber concrete and concrete for road construction.

The specialists from Ludwigsburg are also expert in production of special products such as high-performance concrete, self-compacting and easy-to-compact concrete as well as filler materials and screed production. The SBM Towermix is optimally equipped for meeting the demanding tasks involved – both in terms of structural design and operation.

Long-term success

With the new SBM Towermix, the Ludwigsburg Company emphasizes its long-standing motto: “Union-Beton – High-Quality and Sustainable.” Ernst Stöttinger, Head of Sales for concrete mixing plants at SBM Mineral Processing, subscribes to this motto as follows: “Our systems are indeed much more than the sum of their components. Optimal interaction of the components makes a plant from SBM one of the most future-proof bases for high-quality concrete that a customer of today can expect from us.”

Towards that end, the Austrians depend, for one, on easy accessibility. The company’s operating personnel, for example, reach the mixing room directly from the main building, and all other service levels are easily accessed through the convenient stair tower.
