Mass balances take several forms. In some systems, no material enters or leaves the CV, and the rate of change is not considered important. In such systems, the mass balance simply states that everything that was present in the system at some initial time must be there at all later times, albeit perhaps in different forms.

In a cement plant, nearly 35% heat is lost, primarily from the preheater and cooler waste gases. This corresponds to around 70 to 75 MW of thermal energy. This energy can be tapped by installing a Waste Heat Recovery Power Plant (WHRPP). Size of WHRPP is influenced by the moisture content present in raw material and fuel (coal).

Material from hoppers is fed to mills by passing through weigh feeder with the help of conveyor belts where it is grinded to ultra-fine size less than 90µm. The Raw material fed to mills should be of size range between 75-90mmØ. In vertical roller mills materials is grinded with impact of rollers and moveable horizontal table and hot gases

Vertical cement mills are able to reach production values which are significantly higher than the ones achievable with traditional ball mills, in some cases up to 300 t/h. Empirically, It can be estimated through a simple heat balance that in ball mills only 10% of the energy is used to increase cement fineness, the rest being dissipated basically in form of heat. A VRM allows …
