Long lasting upgrade of location

SBM DYNAMIX® at Frischbeton Eberle

A concrete mixing plant type DYNAMIX® 2500 made by SBM Mineral Processing has been in operation at the Weingarten site of the company Frischbeton Eberle GmbH since late summer last year. For the first time, this semi-mobile plant in an innovative modular design is being deployed together with an equally modular SBM container hopper, which enables the space-saving stockpiling of 540 m3 of aggregates.

Reliable partner in the region

The family-run company with its headquarters in Mochenwangen, north of Ravensburg, Germany, operates a total of four concrete plants and supplies customers in the Upper Swabian region from Ulm to Lindau with an average total production of 100,000 m3 per year. Managing Director Daniel Eberle consistently relies on state-of-the-art technology in concrete production and logistics: The central scheduling department in Mochenwangen receives all customer orders and distributes them to the individual plants according to delivery sites and workload. The company's own 30 truck mixers and dumpers, most of which are designed as swap bodies or semi-trailers, are connected to the head office by GPS and radio data transmission, which optimises order processing and just-in-time deliveries of raw materials from the company's own gravel quarry in Illertissen or regional suppliers.

When it comes to concrete quality the company Frischbeton Eberle leaves nothing to chance: The company also relies on the Alpha Beton® Produktmanagement System (concrete product management system) from the additive specialist BT3, which enables the individual delivery batches to be optimally adapted to delivery routes and handling times by precisely recording all key production parameters (aggregate temperature, water content, etc.) as well as the especially balanced additives. In addition to tailor-made and special concretes, around 80 concrete mixes determine the day-to-day business at all Eberle sites. For a good four years now, these have also included recycled concretes - at the beginning of this year, Frischbeton Eberle also added CO2-reduced concretes to its delivery programme.

Investments in modern delivery plants

High quality standards and the constantly growing product range ask for efficient production plants: Already at the beginning of 2021, Frischbeton Eberle commissioned a stationary concrete mixing plant SBM TOWERMIX® at its southernmost site in Meckenbeuren. Last year, this was followed by the Weingarten site. Originally, only the outdoor aggregate stockpile with a linear dosing feeder was to be substituted by a large container hopper, but during the project phase it was decided to replace the almost 30-year-old mixing plant with a modern plant as well.

In the end of 2022, the decision was made in favour of SBM Mineral Processing and its only recently launched plant DYNAMIX. Thanks to its modular design, the new system could be easily adapted to the existing site, and compared to stationary plants it features absolutely comparable standards regarding product variety, availability, and modern working conditions – but with the long-term investment security of a temporary plant.

The aggregates are now stored in the 19m high container-mobile hopper with automatic loading of the 7 chambers from the directly adjacent 20 m3 feed hopper to allow for economical just-in-time delivery by semi-trailer. After being discharged onto the weighing belt, the aggregate batch is conveyed to the DYNAMIX bucket elevator in a dust-proof enclosure. From the five cement silos (85 m3/105 tons each, 1 x double chamber) and the cement stock in the solidly constructed building with control room and social area, the other components are transferred to the spacious weighing platform above the mixer platform with the BHS DKXS 2.50 twin-shaft mixer (2.50 m3 hardened concrete/batch). An aggregate heating system with temperature measurement and the excellent insulation of the DYNAMIX mixing plant in an attractive winter design ensure reliable year-round operation.

The extensively video-monitored production process in one-man operation is controlled by the Simma Electronic control system used in all Eberle plants, which also ensures the connection to the central scheduling system. "Additionally to the high-quality technical components such as the BHS mixing technology, which had already impressed us at the TOWERMIX plant concerning mixing quality and speed, it was the particularly flexible response to our requests regarding the technical equipment that ultimately tipped the scales in favour of SBM Mineral Processing," says Managing Director Daniel Eberle. "The plant manufacturers perfectly adapted their modular technology to our requirements: One example of this is the lateral positioning of the feed hopper and bucket elevator at the high aggregate hopper, which, in contrast to other solutions, offers us significantly more manoeuvring space," says Daniel Eberle, summarising the good cooperation over the approximately eight-month long planning and construction phase.
