Temperature Measurements in Cement Manufacture ...

Dec 14, 2018· The Rotary Kiln. The rotary kiln is the key component in a cement plant. It is a long steel cylinder, lined with refractory brickwork to protect the outer shell from the high temperatures of the interior. The kiln is very large, up to 4 m diameter and up to 50 m long. It typically rotates three to five times per minute.

Improvement of a cement rotary kiln performance using ...

In order to investigate the effect of parameters and system optimization, the processes must be modeled first. Cement rotary kiln systems are complex because of non-linear, time invariant and full of behavioral uncertainty where the mathematical modeling of the plant is impossible. Artificial neural network (ANN) is one of the best tools for improving the performance of such processes.
