Since 1974, the number of wet process kilns has dropped from 234 to 25 a decline of 89 percent while the number of dry process kilns has only been reduced from 198 to 124. Well over three quarters of existing clinker production capacity has been built since 1975 all utilizing the dry manufacturing process.

The kiln has to operate continuously in order to ensure a steady regime, and therefore uniformity of clinker. The larger existing kiln in a wet process plant produces 3600 tonnes of clinker per day. The manufacture of cement by wet process is energy intensive and thus uneconomical as compared to dry process and semi dry process.
Cement manufacturing: components of a cement plant. This page and the linked pages below summarize the cement manufacturing process from the perspective of the individual components of a cement plant the kiln, the cement mill etc.. For information on materials, including reactions in the kiln, see the '' Clinker '' pages.

The process feedstock is fed into the upper end of the cylinder. As the kiln rotates, material gradually moves down toward the lower end, and may undergo a certain amount of stirring and mixing. Hot gases pass along the kiln, sometimes in the same direction as the process material (cocurrent), but usually in the opposite direction (counter ...
Rotary kilns work by processing material in a rotating drum at high temperatures for a specified retention time to cause a physical change or chemical reaction in the material being processed. The kiln is set at a slight slope to assist in moving material through the drum.
