· Rotary kilns, with or without preheaters, usually process raw dolomite with material size between 10 mm and 50 mm. The heat balance of this type of kilns is egorized by somewhat high losses with the offgases and through the kiln shell. Typical values for the offgas losses are in the range of around 25 % and for kiln shell losses are in the range of around 20 .
