4 Due to the interaction of raw materials and kiln gases, rotary kiln systems have inherent SO2 removal efficiencies ranging between 40-99% of the sulfur input to the system. The literature suggests that 50-70% of the remaining SO2 will be removed from exhaust gases when passed through an in-line raw mill .
Nov 19, 2014· White cement is typically exported longer distances than grey cement, which means production is not limited by domestic demand. Egypt is the world's largest producer of white cement in 2014 (Table 1, Figure 1), with an installed production capacity of >2.69Mt/yr from five plants.

Cement production process typically involves (i) grinding limestone (and other raw materials to achieve the right chemical composition) to about 90% passing 90 μm screen in a dry circuit, (ii) making cement by the chemical reaction between the components of the ground mixture. This chemical reaction occurs at high temperature in a rotary kiln.
