Clinkerization - Cement Plant Optimization

Main factors dictating size of kiln are the retention time (25-30 minutes) of material in kiln, degree of filling (10-17%) and thermal loading of burning zone (2.8-4.8 x 10 6 kcal/h/m 2). Pre-calciner kilns are shortest in length, as 90-95 % calcination is completed outside the kiln.

Thermodynamic Analysis of Cement Production Process …

Previous work on exergy analysis of cement has sometimes been focused on the sub systems such as the rotary kiln [9], and the raw mill [10]. Most work has been on using only the operating data of the cement industry for the exergy analysis. This does not give room for parametric analyses that could give . suggestions for improvement of the process.
