Lime Production from Limestone - Current Technology

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.
