difference of rotary kiln between wt and dry process of cement

Apr 14, 2017· Rotary kilns are broadly categorized as dry- and wet-process kilns, depending on how the raw materials are prepared. Wet-process kilns arefed raw material slurry with moisture content ranging between 30% and 40%. A wet-process kiln needs additional length to evaporate the water contained in the raw material feed
