Abstract. This study aimed at optimizing both the energy efficiency and the quality of the end product by modifying the existing flowsheet of the cement grinding circuit. As a general application, mill filter stream is sent to the air classifier owing to its coarser size distribution than the desired product. However, the study proved that some ...
Raw Mill Exhaust Fans. Raw mill exhaust fans/ stack fans also known as de-dusting fans handle 2.2 tons of exhaust gases for the production of 1 ton of clinker. Raw mill exhaust fans are operated in a cement factory with very adverse situations because these fans mostly handle gases like CO2, N2, NOx, and Sox along with some dust …

In a dry grinding system, the BNN results showed that ventilation, as an efficient factor, could be accurately predicted through a conscious lab procedure. BNN could accurately predict the measuring pressure before and after the mill fan, with R2= 0.77. A comparison between BNN outcomes and random forest/support.
