Model parameters for the particle breakage and classification action with/without the classifying liner were obtained from the available literature for cement clinker. Experimental residence time distribution data for a full-scale cement ball mill was fitted by the cell-based PBM to determine the number of cells and axial back-mixing ratio.

The cement mill power consumption data have temporal characteristics, so the long and short term memory network (LSTM) proposed in the literature is used to model the cement mill power consumption. On the one hand, LSTM has the memory ability of recurrent neural network to deal with time series problems, and on the other hand, it …
