1117 Lime Manufacturing 11171 Process Description 15 Lime is the hightemperature 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
[email protected]A lime kiln uses heat motion and airflow to convert lime mud to lime or in chemical terms calcium carbonate to calcium oxide this process is referred to as calcining the most common lime kiln designed found at kraft pulp mills is the rotary lime kiln
