The clinker is ground to a fine powder in a cement mill and mixed with gypsum to create cement. The powdered cement is then mixed with water and aggregates to form concrete that is used in construction. Clinker quality depends on raw material composition, which has to be closely monitored to ensure the quality of the cement. Excess free lime ...

The liquid percentage at 1450 0 C can be estimated using the formula. % Liquid content (1450 0C) = 3.0 x A+2.25 x F+S. Where A=Al 2 O, F=Fe 2 O 3, S= MgO+K 2 O+Na 2 O+SO 3 In Clinker. The normal range of liquid phase is 22-27%. Burnability is a reference value for raw meal indicating how difficult it is to burn.

In order to produce raw materials preparation, clinker and rotary kilns are widely used in cement plants. The objective of this study is to perform energy and exergy analysis of a raw mill (RM) and raw materials preparation unit in a cement plant in Turkey using the actual operational data. The RM has a capacity of 82.9 ton-material hourly.

For example, assume that raw ore is a two component system comprised of a valued mineral and host rock having relative densities of 6.30 and 2.65, respectively. The amount of valued mineral is 30% of the total ore.Total Solid Mass, M: Mineral + Host Rock – 30 + 70 = 100 Total Volume, Vs: Total Solid Relative Density
