Construction transport and concrete filling station

High-quality concrete production on the premises of the haulage company A. Heßler in Gräfenberg was a dusty, time-consuming and labour-intensive business. The new fully automatic CFS 30 SL Elba concrete mixing plant from Ammann changes all that.

A compact concrete plant – for the company's own use and as a concrete filling station – has recently been installed on the industrial estate in Gräfenberg in Bavaria. The CFS 30 SL Elba concrete mixing plant from Ammann expands the product range of owner Alexander Heßler's haulage company that specialises in construction transport.

“I took a look at the plant during my visit to the bauma trade fair in October 2022 together with the customer advisor from BIV – a dealer for Ammann compaction equipment.” said Alexander Heßler, owner of the haulage company A. Heßler from Gräfenberg, Bavaria. The continuous availability of concrete, even on Friday afternoons and Saturdays, were his main reasons for choosing this concrete plant. “This shortens my distances immensely: it means no more lengthy transport of concrete for producing our own concrete Lego bricks.” explained Heßler.

Until now, the production of concrete with a tractor pto mixer was not satisfactory. The manual addition of aggregates and bagged cement was very labour-intensive and dusty. “We were also only able to achieve consistently good concrete quality with great effort.”

Compact, powerful concrete filling station

With the Concrete Filling Station CFS product series, Ammann Elba offers reliable and economical concrete mixing plants for use in the recycling, landscaping, concrete products and precast concrete sectors. In addition, these plants give operators the opportunity to supply small quantities of concrete to regional craft business.

Alexander Heßler had a look around the trade fair stand and, after extensive consultation, opted for the CFS 30 SL Elba system. All components are weighed and dosed separately and concrete production is controlled fully automatically.

The CEM 500 S mixer enables high hourly output capacity of up to 30 m³ and fast, homogenized mixing. Operation is simple. The concrete filling station can be operated intuitively via the S-Mix automatic control system with freely selectable recipes and production quantities using a touchscreen.

A pocket storage container for four aggregate types of 2.5 m³ each is integrated for storing the aggregates, as well as dosing and weighing. The feeder lift up the aggregates to the mixer. The automatic water and additive dosing system ensures consistently good concrete quality. The cement weigher can be connected to two types of cement, the cement is weighed separately and dosed directly into the mixer. This prevents exposure of the company's employees to dust emissions. In addition, an admixture dosing system for the production of concretes with special properties was integrated.

The quality of the concrete produced corresponds exactly to the required specifications and the concrete output also fulfils the contractor's expectations. “Every beginning is difficult. The new technology demanded a lot from us.” said Alexander Heßler. “The way of producing consistently good concrete to specified recipes without knowing the process of an automatically operating plant took some getting used to at first.” However, with the support of the Ammann Elba service team and thanks to the excellent training, the handling became more and more routine.

Alexander Heßler is very satisfied. “The service, the advice from the Ammann employees and the product quality of my concrete are just right.”
