How is cement manufactured and used? - Quora

The cement manufacturing process starts with the mining of limestone that is excavated from the open cast mines. Then this limestone is crushed to -80 mm size and is loaded in logitudinal stockpiles for grinding in raw mill hoppers. As mentioned earlier coal is used as a fuel to heat the raw materials in the cement manufacturing process.

11.6 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 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.
