lime kiln process

The lime kiln is an important part of the recaust and recovery process in a mill In the evaporation section of the kiln chains which drag through the lime mud increase the drying area and evaporation rate of the kiln Heat for the calcining reaction is supplied by a large burner at one end of the kiln
