1. Lime rotary kiln is the core equipment in the process of lime calcination. The related equipments of the production line are bucket elevator, lime rotary kiln, cooler, belt conveyor, dust collector, etc.

2. Lime rotary kiln production line refers to the operating line of active lime production. The adoption of vertical preheater makes precalcining rate of limestone can reach 25%, the outlet temperature of flue gas down to about 250 ℃, the pre-heating effect improved, and the energy consumption index decreased by about 5%. 

3. At present, the refractory materials and masonry structures are optimized, which makes the decomposition rate reach 30% and the production capacity reach 150-1000t/d.


1. Limestone is mainly composed of calcium carbonate, and the application of limestone is very extensive. The limestone can be directly processed into stone and burned into quick lime. 

2. Besides, limestone is widely used in construction, coating, chemical industry, building materials and other fields, which makes a great contribution to the development of the national economy. Limestone has the characteristics of chemical resistance, acid resistance and various gases resistance.

3. Lime rotary kiln production line is a relatively mature technology in China. With the constant innovation of production technology of rotary kiln and the demand of market development, the production process of lime rotary kiln is more and more sophisticated, which makes the rotary kiln more adaptable to limestone.
