Energy Balances and Efficiency

Energy Balances and Effciency

Learn how to conduct and evaluate cement kiln trials and mill trials. Kiln and mill examinations are carried out in order to gather data on the performance and to validate warranty performance data such as the output, the energy consumption, input/output ratio or the effciency. They also provide a reliable foundation for the optimisation of individual operational system components, the cement quality, the reduction of emissions levels and for assessment of material cycles and coating formations.


  • Basics of conducting balances
  • Planning, organisation and realisation of plant examinations
  • Introduction into calculation of energy and mass balances
  • Introduction into measuring techniques
  • Case studies: Calculate an energy balance of a cyclone preheater plant, mass balance of a cyclone preheater
  • Effcient mill operation (Ball mill; Roller press; VRM)
  • Examinations of cement mills (focus on ball mills)
  • Case studies: Ball mill examinations / audits
  • Discussion of participants’ specific questions and problems
  • Plant visit


  • Presentaions, interactive exercises
  • Class room training
  • Site visit

The training is led by highly skilled and experienced engineers.

Upon successful completion of the training course the participants will receive a certificate of attendance.
