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.
Heat consumption of different lime kiln types Calcination of limestone and dolomite is an energy intensive endothermal process. Until today the thermal energy in lime kilns is provided by combustion of fuels. Depending on the availability of the fuels the cost of thermal energy varies between 20% and 50% of the production cost.

Operation of Kilns Handling the Product Lime is a very general term applied to products of limestone, in popular treatises often incorrectly, including ground or pulverized limestone used in agriculture. When used without qualifying adjective, the term usually means burned or calcined limestone, or quicklime, or calcia.

Lime kilns are usually inclined at about 3°–5° slope with material charged at the elevated end and discharging at the lower end. The degree of fill is relatively deep, about 10–12%. Owing to its low thermal conductivity, limestone with a large diameter of about 2 in (5 cm) results in higher effective bed heat conduction than smaller stones.
The essential part of the refractory materials production on a basis of sintered dolomite as raw material is the process of dolomite calcination. The technology process usually takes place in shaft or rotary kilns, where the dolomite stone, CaMg(CO3)2, is subjected to a high temperature heat treatment. The calcination of the dolomite is highly endothermic reaction, requiring …
You can add dolomite lime to water to raise the pH and to buffer the pH. According to the University of Alabama Extension, dolomite lime helps to maintain pH between 7.0 and 8.5 (by acting as a buffer). It also makes nutrients more available to organisms in the water, such as algae . The best time to lime a pond is before you fill it.

Limestone Calcination Process To produce quicklime in lime kilns, there are mainly three processes. The first stage is preheating. The second stage is calcining. And the third stage is cooling. In the preheating stage. The feed limestone is preheated by the exhaust hot air from the lime kiln, so that partially of the limestone will be calcined.
