The implementation of process technology plays a pivotal role in the production of quality concrete. The as1 plant control system for concrete mixing plants from Ammann employs various functionalities to ensure a high dosage accuracy and water content control; these include:

• Accurate dosage true to recipe thanks to dynamic flow measurement and self-learning auto-correction of overrun parameters for all components
• Dynamic consistency control to safeguard the water/cement factor
• Linearisation of dosage metering for concrete mixing plants with volumetric metering
• Sampling scheduling module for mixtures in accordance with EN 206-1

A high degree of automation brings additional relief to mixing engineers. Intelligent mixing flap control enables a much faster loading of concrete lorries or the filling of mineral silos directly from the gravel mine.
