A lime kiln is used to convert calcium carbonate caco3 into burnt lime cao. the burned lime reacts with the green liquor and precipitates as caco3, thus creating a closed loop with the recausticizing. the valmet lime kiln is based on a long line of successful projects starting in 1904 taking the production from just 15 tpd to 1,250 tpd.

A very hot material discharged from a rotary kiln or similar equipment can damage your downstream process and handling equipment. common examples are limestone exiting a kiln and fly ash discharging from a boiler. a screw conveyor can be designed to cool the material as its transferred for instance, cooling a material that leaves a kiln.
