In addition, the required precalciner volume of tertiary air flow precalciners is less than the volume required for total flow and hybrid precalciners. Examples of the currently used total flow and tertiary air flow precalciners are, respectively, the F. L. Co.'s In-Line Calciner (Figure 3.2.6), and Separate-Line Calciner (Figure 3.2.7).

The materials reach temperatures of 2500°F to well above 3000°F in the kiln. Rotary kilns are divided into two groups, dry-process and wet-process, depending on how the raw materials are prepared. In wet-process kilns, raw materials are fed into the kiln as a slurry with a moisture content of 30 to 40 percent.
