Lime Production: Industry Profile

Lime kilns can be categorized into three groups: rotary kilns, vertical kilns, and miscellaneous. About 90 percent of commercial lime capacity in the U.S. is calcined in rotary kilns. Most of the remaining capacity is processed with vertical kilns (vertical kilns are more common in captive supply facilities), and small quantities are processed ...

11.17 Lime Manufacturing - US EPA

11.17 Lime Manufacturing 11.17.1 Process Description 1-5 Lime is the high-temperature product of the calcination of limestone. Although limestone deposits are found in every state, only a small portion is pure enough for industrial lime manufacturing. To be classified as limestone, the rock must contain at least 50 percent calcium carbonate.
