Just over 150 cement kilns operate in the United States and, each year, they "cook" thousands of tons of rock — primarily limestone — at more than 2,600 degrees Fahrenheit. To fuel this cooking process, cement kilns burn primarily coal. Both the rock and the coal contain mercury, a highly volatile metal that evaporates at room temperature.

to a dry kiln. Wet-process kilns tend to be older operations as compared to dry-processes where raw materials are fed into the process as a dry powder. There are three major variations of dry-process kilns in operation in the U.S.: long dry (LD) kilns, preheater (PH) kilns, and preheater/precalciner (PH/PC) kilns.
