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 .
