Technology Upgrade Facilitates Long-Lasting Success

Union-Beton replaces old plant in Ludwigsburg with the latest TOWERMIX® D9-series.

As a rule, stationary concrete mixing plants last for decades. Nevertheless, eventually the time comes for everything. After 48 years, the company Union-Beton GmbH & Co. KG needed a new production basis in Ludwigsburg to continually ensure its excellent position in the market. This asked for a powerful and tailor-made technology which brought together Union-Beton and SBM Mineral Processing. With their stationary plant TOWERMIX® 3000 + 1670 ST D9 450 V the leading Upper Austrian innovators for concrete mixing plants provided a most satisfactory solution.

SBM Mineral Processing is one of the few enterprises in the industry that can righteously claim to be more than a manufacturer of concrete mixing plants. That was an essential factor for Union-Beton. The new TOWERMIX® 3000 + 1670 ST D9 450 V was to be placed on the existing foundation of the present plant. One of the core competences of SBM Mineral Processing offered the optimum solution: A comprehensive turnkey concept from a single source that covers everything from disassembling the old plant to commissioning the new TOWERMIX®.

Everydays for future!

The new plant must meet both present and future requirements, e.g. concerning sustainability.  In a fast-moving working environment with quickly changing regulations the plant manufacturer had to face especially ambitious demands. SBM Mineral Processing has more than 40 years of experience in concrete technology which once again have been bundled up in the ground-breaking plant TOWERMIX® 3000 + 1670 ST D9 450 V.

Technically speaking this means for TOWERMIX® at Union-Beton high-pressure cleaning as well as integrated video surveillance for the two twin-shaft mixers type BHS DKXS with an output of 3.00 m³ and 1.67 m³ of hardened concrete per batch. This performance results in a total capacity of up to 140 m³ per hour. With respect to a contemporary CO2 footprint, sustainable operation throughout the year is allowed for due to an efficient heating and cooling system for both aggregate storage and mixing water and space heating in the solid tower – additionally optimised by winterproof closed insulation. Thanks to the compact construction of the TOWERMIX® D9 series, two extra-wide lanes for the truck mixer could also be implemented. Another sophisticated detail: To improve the material supply logistics a vehicle-resistant feed hopper with hydraulically operated hopper cover was installed on site.

 You order, we mix!

The raw materials supply of TOWERMIX® is ensured by an aggregate storage with eight chambers and a total of 450 m³ buffer. Thanks to extra-steep discharge cones even poor-flowing aggregates will be completely emptied. The corresponding cement storage comprises four silos with 2x 60 tons each; two of those cements are dosed and weighed in in a separate weighing system for the self-levelling floor production.  By means of a separate dosing and weighing system up to six additives can be added directly to the mixer. This comprehensive configuration is necessary to be able to mix the wide selection of concretes offered by Union-Beton. The product range includes normal concrete as well as exposed concrete, steel fibre concrete, and concrete for road construction. These experts from Ludwigsburg are even well versed in providing special products such as high-performance concrete, self-compacting and high-compacting concrete as well as backfill material and screed. As to design and operation the plant SBM TOWERMIX® is optimally suited to meet these challenging demands. A microprocessor control of the latest generation from Dorner Electronic precisely runs all processes of the mixing plant.

Long-lasting success

With the new SBM TOWERMIX® the company from Ludwigsburg once again underlines its traditional slogan: “Union-Beton – Long-Lasting Top Quality!“ Ernst Stöttinger, Head of Sales for concrete mixing plants at SBM Mineral Processing gladly undersigns this motto: “Our plants are certainly much more than just the sum of their parts. The optimum combination of the components makes an SBM plant the future-proof and sound basis to produce premium-quality concrete. And our client is entitled to expect this from us today”. To obtain this target the Austrian company bets on e.g. simple and easy accessibility. The operators can reach the mixing area directly from the control room and all other service levels are quickly accessible by the comfortable stair tower. The complete supporting structure is galvanised which also guarantees a high stable value. This SBM combination of first-class construction and advanced technology stands for another motto Union-Beton uses to describe its products: Quality thanks to Experience.
