What is Lime Kiln?

Limestone is a natural rock with the main component of calcium carbonate whose Mohs hardness is 3. It can be directly processed into stone materials and used for industrial products such as in building materials, highways, metallurgy, chemical industry and so on. Besides, lime can be fired into quicklime, and used in the industries of water quality treatment, asphalt improvement, desulfurization, building materials, medicine and the like.

Lime kiln is also named as limestone rotary kiln and active lime kiln, which is the main equipment for calcining active lime into carbon dioxide and calcium oxide, the latter of which is what we call quick lime. With advantages such as reasonable structure, good sealing property, less thermal radiation loss, and high level of automation, FTM has models of customized lime kiln for sale.

Working Principle of Lime Kiln

Structure of Lime Kiln

The main structure of limestone rotary kiln includes the supporting device, kiln head, kiln tail sealing device, rotary cylinder, coal burner and so on. The kiln body is located on the roller and has a horizontal inclination of about 3 °. The supporting wheel device is used to support the whole kiln body, and the retaining wheel device is used to control the movement of the kiln body up and down.

Lime Kiln Working Process

When lime kiln works, crushed lime in the material bin is screened and lifted to the upper bin of the pre-heating device. Then it is scattered in each room of the pre-heating device and gets heat exchange with smoke. Herein the lime is 30% decomposition. Fully preheated lime gets into the calcination through the tail chute. Lime goes slowly through the pre-heating zone, calcination zone and cooler, in which process, it is calcinated into CaO and CO2. Finished lime is cooled below 100℃ and exhausted out to the store by bucket elevator and belt conveyor.
