[0002] A white lime kiln is a device for producing white cement. White cement is a special type of cement, whose main components are limestone, dolomite and gypsum, without iron ions, so it shows the characteristics of white or light gray. The white lime kiln is a device for calcining raw materials limestone and dolomite. Through chemical reactions and physical changes at high temperatures, the raw materials are transformed into white cement clinker.
