Energy savings in cement production

Switching from manual operation to fully automated real-time monitoring and advanced process control

Few years ago Vulcan Materials Company upgraded its cement finishing circuit by installing an Advanced Process Control (APC) solution from Pavilion Technologies, a Rockwell Automation company, and real-time particle size analysis from Malvern Instruments. Together these solutions have transformed operation, highlighting more productive control strategies and delivering major gains, including:

  • A 15% improvement in one-day strength (although the plant is now targeting a 10% lower Blaine)
  • A 20% reduction in specific energy consumption, the amount of energy used to mill each tone of cement
  • A 15% reduction in ball mill charge

Based on energy savings alone the company estimates that the payback period for the entire project (advanced control system and on-line particle size analyzer) is less than one year.

 

 

 

 

 

 

 

 

 

 

 

 
John Murphy III, Production Manager, at Vulcan Materials Company says; “Together the technologies have revealed how to operate the plant in a very different, much more efficient way. We have reduced costs and have simultaneously improved product quality even though we are now targeting a very much lower Blaine, the standard industry measure used to quantify fineness.
