Refratechnik - Lime shaft kilns

As opposed to rotary kilns, shaft kilns are static production systems in which the raw material (limestone in various particle sizes) is fed into the kiln from the top, from where it moves downwards through the kiln shaft purely by gravity. By introducing heat energy (fuel), a chemical reaction (dissociation) takes place, whereby the limestone (CaCO 3) is split up into lime (CaO) and carbon ...

Everything You Need to Know on Rotary Kiln Refractory

Only direct-fired rotary kilns employ refractory; in an indirect-kiln, heat transfer occurs primarily through the kiln shell wall. Refractory would be another barrier for heat to pass through before it is in contact with material, reducing the efficiency of the process. Because of this, instead of using refractory, indirect-fired kilns typically rely on a more heat resistant shell.
