The raw vertical roller mill has four rollers, 3000 KW main drive, m table diameter, m roller diameter with 330 t/h capacity (made by LOESCHE Company from Germany).
Raw mill is also called cement raw mill, similar to cement ball mill, it is an important cement milling equipment used in the cement production process. Raw mill is mainly used for grinding cement raw meal in the cement factory production process. It is also suitable for metallurgical, chemical, electric power and other industrial mining enterprises to grind various ores and other grindable ...
The accurate prediction of raw meal fineness in the vertical mill system is very helpful for the operator to control the vertical mill. However, due to the complexity of the industrial environment, the process variables have coupling, timevarying delay and nonlinear characteristics in the grinding process of cement raw material.

The authors Ajaya and Hare have successfully made a benchmark with different nonlinear models to predict Blaine's fineness in vertical cement mills [10, 11]. Accurate model performance was obtained using Back Propagation Neural Network (BPNN) and Adaptive Neuro Fuzzy Inference System to predict cement Blaine in vertical mill [10, 11].
