2013年4月7日 can you please share your opinion about the what are the main levers to control the blaine and residue on 45 micron in cement product indivisually. take any case -1 , our blaine is 3400 cm2/gm and residue on 45 micron is 13% and if we want to reduce the residue by 3% with out affecting the blaine, how it is posible? (or vise versa). thanks. regards

This study proposes a method for modeling the Vertical Roller Mill (VRM) to predict residue 90 micron and residue 200 micron of the raw meal product using Back Propagation Neural Network (BPNN). The modelling step is input preparation, Artificial Neural Network (ANN) structure determination, optimizer and loss function selection, training ANN and model evaluation. In
