Lime | SpringerLink
Lime is the least expensive and one of the most heavily used alkali in the world, being essential to our society. It is a nonhydraulic binder, excepting the so-called hydraulic lime, meaning that it will not set under water.For this reason, lime is sometimes called air lime since it hardens on exposure to air. It was used for thousands of years in masonry mortars to bind the …

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 …

Rotary kilns generally require more heat than shaft kilns. The heat use tends to increase as the degree of burning increases. The net heat use varies between 3 600 and 7 500 MJ/Mg of lime for calcium quicklime and light- and hard-burned dolomite, and between 6 500 and 10 500 MJ/Mg of lime for dead-burned dolomite (European Commission, 2001).
