1. Activity is higher than the traditional shaft kiln 30ml
The material heated evenly in the revolving lime kiln, the probability of mild and excessive calcination is low. The lime activity degrees produce by lime rotary kiln is higher than the shaft kiln. The lime activity can reach up to 400ml.
2.Production capacity reaches up to 1500 t/d
The lime kilns produced by Great Wall Machinery have large capacity, the output can reach to 1500t/d, operating well to guarantee enterprise up-scaling and reduce the production cost.

3. Auto-control reduce the labor cost
Auto-control by using DCS remote control system, only need 2-3 operating personnel in the whole line.
4 Good quality of finished products, low probability of mild and excessive calcination
Product quality is uniform, the probability of mild and excessive calcination less than 8%.
5 Gas fuel, energy saving and environmental protection
Great Wall lime kiln belongs to open type calcination equipment with advanced manufacturing technique，lower energy consumption than the old lime kiln calcination system and more environmental protection for adopts the exhaust blast furnace gas.
