Material: Limestone, Dolomite, Kaolin
Application: Limestone calcination
Lime rotary kiln is used to produce quicklime through the calcination of limestone (calcium carbonate). Lime rotary kiln is specialized design for production of active lime.
ZK lime rotary kiln can work with vertical preheater and vertical cooler to achieve the advantages like high use ratio of raw materials, complete calcination, even quality, good quality lime, high capacity output, environmental and energy saving, simple operation and longer working life. This kiln is very suitable for limestone calcination for industries like metallurgy, chemical, construction materials and etc.
