  • 11.6 portland cement manufacturing

    Aug 17, 1971· kiln. depending on the process type, kilns have length-to-diameter ratios in the range of 15:1 to 40:1. 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. wet process and long dry process pyroprocessing systems consist solely of the simple rotary kiln.
