At present, few people pay attention to the coupling characteristics among variables, thus solving this problem is particularly important in raw meal fineness prediction. In this article, we propose a two-dimensional convolutional neural network method that is used to predict raw meal fineness during the grinding process of raw material.

Cement Raw Meal Grinding. Apr 06, 2019. Divided into two methods: dry and wet. The dry method generally adopts a closed-circuit operating system, that is, after the raw materials are ground by a grinder, they are sorted into a sorting machine, and the coarse powder is returned to the grinding mill for re-grinding operation, and most of the ...

In this study, production capacity of a fully air-swept dry grinding raw meal ball mill circuit was evaluated by modelling the mill using the perfect mixing modelling approach (Whiten, 1972).
