116 Portland Cement Manufacturing
Aug 17, 1971 In the wet process and long dry process, all of the pyroprocessing activity occurs in the rotary kiln. Depending on the process type, kilns have length-to-diameter ratios in the range of 151 to 401. While some wet process kilns may be as long as 210 m 700 ft, many wet process kilns and all dry process kilns are shorter.
