Cement factories require large amounts of energy. 70% of the variable cost goes to energy—33% to kiln thermal energy and 37% to electrical energy. This paper represents the second stage of a broader research study which aims at optimising electricity cost in a cement factory by means of using artificial intelligence. After an analysis of the different tools that could be highly useful for ...

It has been established that about 710% of the cement can be lost due to uncontrolled emissions in the cement mill [ 21 ]. Some studies show that 45% of dust emissions are due to the furnace's supply, while other dust emission sources are crushers, clinker coolers, grinding, and material handling equipment [ 35 ].

In cement mills, ventilation is a critical key for maintaining temperature and material transportation. However, relationships between operational variables and ventilation factors for an industrial cement ball mill were not addressed until today. This investigation is going to fill this gap based on a newly developed concept named "conscious laboratory (CL)".
