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.

Rotary Kilns KHD International

2021-11-26  Kiln plants with two and three station rotary kilns from KHD Humboldt Wedag are top of the line. One reason: highly efficient precalcining systems, which were developed by KHD Humboldt Wedag, revolutionizing the clinkering process. Rotary kilns no longer have to function as calciners which mean that they can be substantially smaller in size.

Clinker Production an overview ScienceDirect Topics

As the change in cement kiln size is difficult, waste heat recovery may play an important role. Currently, a large quantity of low temperature waste heat (below 350 °C), approximately 30% of the total heat consumption of the system, is still not recovered and could be a promising low investment cost solution (Jintao et al., 2009).
