Ammann introduce Drying Expert ADX system
New ADX technology from Ammann simultaneously regulates material and raw gas temperatures
AMMANN have developed a burner power and dryer RPM system that is both automated and combined.
The patent-pending Ammann Drying Expert (ADX) automates both the burner power and the dryer RPM setting for virgin and RAP dryers, with the potential for saving fuel during production.
Simultaneously automating control of the material temperatures – by varying burner power – and raw gas temperatures – by varying dryer RPMs – has proven difficult.
The ADX controller eliminates the need for manual interventions by the operator to regulate burner power and dryer RPMs due to changing conditions. This prevents inefficient fluctuations and ensures a highly consistency material temperature.
With ADX, too high and too low material and raw gas temperatures will be avoided to the maximum, providing potential fuel savings and a host of other benefits, including:
Increased operational safety
Continuous operation protects plant components and materials
Operational adjustments are automated and executed more accurately than by hand
Temperature limits cannot be exceeded, preventing damage to plant components and associated downtime and energy-intensive restarts
Increased product quality
Avoidance of too low/too high material temperatures at the dryer outlet improves consistency
Optimum material temperatures results in more uniform mix quality
Improvement of mix processability
Improved ease of use
Operator can focus on other tasks during operation.
ADX is run through the Ammann as1 control system and can be included when purchasing a new plant, although retrofits are also available. The only requirement is a variable-speed drive.
ADX is currently released for virgin aggregate, RAH60 and RAH100 dryers on Ammann ABA UniBatch and ABP Universal asphalt-mixing plants in most of Europe.
