Introduction of Lime Kiln

As a kind of rotary kiln, the lime kiln, also called active lime rotary kiln, is the main equipment used to calcine active lime, consisting of the drum body, support device, support device with hydraulic retaining wheel, transmission device, lubrication device, sealing device for kiln tail. It is of simple structure, reliable operation, and convenience in the automation control.

Lime Kiln Performance Features

The lime kiln has the advanced structure and adopts the both-ends combined sealing scales, which can decrease the possibility of air leakage. The Kiln lining is made from composite refractory material to reduce heat loss. The waste heat can be made full use of to preheat the air, going into the kiln next time, to reach up to above 700℃ to save the energy consumption.

Lime Kiln Working Principle

Inside the kiln, coal powder or natural gas generates quantity of heat, which, by the transfer of air, heats the material. At the moment, with the constant rotation of the kiln body on the basis of the design of the slope and speed, the material rolls and advances inside the kiln periodically from the feeding end toward another end. In this period, the material has been calcined into the qualified clinker.
