Challenges in Limestone Processing

Rotary kilns are most often used to produce lime products in the United States. Hot combustion gases and limestone move counter currently within the refractory-lined drum of the rotary kiln, applying a high-temperature process that ultimately changes the raw material into a high calcium lime or dolomitic lime.

Lime Production from Limestone - Current .

Limestone is a source of calcium carbonate and is heated to convert the calcium carbonate into calcium oxide. This process is generally carried out in large rotary kilns or vertical shaft kilns where high temperature is required. Quicklime is produced in the calcination process, which can be crushed depending on it's use.
