Enhancing kiln control

30 November 2012, Published under Cement News

The major costs of clinker production are incurred in kiln pyro-processing, so it’s no surprise that this part of the process received more attention than any other. To-date, the trillions of tonnes of clinker manufactured have been produced in plants controlled mostly on elemental chemical data. Bogue equations construct hypothetical mineral compositions that ignore the heat treatment in the kiln.  Kiln control with COSMA on-line Mineral Analyser Fuel combustion specialist FCT...
