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.
