slurry mining
3.Based on the analysis of the characteristics of the raw mix slurry preparing process in alumina sintering production process, firstly, a mechanism model based on material balance principle was established as the master-rule model for the quality prediction; secondly, considering the problem that the alkali liquor composition was unstable and its real-time measurement was difficult, a NN (neural networks) prediction model for the prediction of the alkali liquor composition was set up and nesting-integrated with the mechanism model; finally, using the gray theory for the information mining from the errors of the mechanism model, a GM(1, 1) compensation model was put forward and parallel-connection-integrated with the mechanism model, achieving a raw mix slurry quality prediction model.
