Transforming stone into lime or dolime Lhoist Minerals

Mixed-feed shaft kilns are usually constructed as a group of kilns in which the limestone (or dolomite) is mixed with a charge of solid fuel. Cooling air for the lime is blown in through the base to serve as combustion air for the fuel mixed with the stone at the head of the kiln. These kilns can generate extremely high temperature peaks.

Lime kiln Wikipedia

A lime kiln is a kiln used for the calcination of limestone (calcium carbonate) to produce the form of lime called quicklime (calcium oxide).The chemical equation for this reaction is . CaCO 3 + heat → CaO + CO 2. This reaction takes place at 900 °C (1,650 °F) (at which temperature the partial pressure of CO 2 is 1 atmosphere), but a temperature around 1000 °C (1800 °F; at which

Kiln Types EuLA: European Lime Association

Rotary kilns consist of a rotating cylinder inclined at an angle of 3 to 4 degrees to the horizontal. Limestone, chalk or Dolomite is fed into the upper ‘back end’, and fuel plus combustion air is fired into the lower ‘front end’.The product is then discharged from the kiln into a cooler, where it is used to pre-heat the combustion air.
