Calcination — Science Learning Hub

An excavator loads the loosened limestone into dump trucks for delivery to the on-site crushing plant. This continuous-feed process crushes limestone chip into a range of sizes. Limestone chip 15–50 mm in size is sent to the calcination plant, while other sizes are used in other processes. Acknowledgement: McDonald's Lime Limited. Step 3.

Calcination furnace & calcination oven - Carbolite Gero

The calcination process normally takes place at temperatures below the melting point of the product materials. One of the most common applications is as a step in the production of Portland cement, in which calcium carbonate (limestone) is calcined at around 850°C to produce calcium oxide (quicklime) and carbon dioxide.

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.
