11.6 Portland Cement Manufacturing
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 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.

Revealing the numbers behind calcined clay
One of the great benefits of calcined clay is that it activates at a much lower temperature than that required to make clinker. With temperatures of 750 – 850˚C instead of 1400 – 1500˚C and much lower costs for grinding and handling, you gain significant fuel and power savings – 30% and 40%, respectively – when comparing the operating cost to make 1 tonne of clay versus 1 …
