Lime Kiln Features 
 The lime kiln is new with vertical preheater and vertical cooler lime kiln, 
 An advanced structure, low pressure loss of the vertical preheater can effectively improve the warm-up effect, the decomposition rate of limestone kiln preheated up to 20-25%, and direct use of 10-15mm fine-grade limestone; 
 2, the combined scales of reliable rotary kiln at both ends sealed. So that the air leakage coefficient is less than 10% of the composite refractory material in order to reduce radiation heat loss; 
 3, the filling can partition ventilation round or square vertical cooler, resorted to the lime of the cooler temperature of 800C + ambient temperature, to facilitate transportation, storage, and can be kiln secondary air is preheated to above 7000C, and reduce moving parts and special materials. 
 4, the high quality of raw material and good quality of lime; fuel of high calorific value, the number of consumption. 
 5, limestone particle size and is proportional to the calcination time; the quicklime degree of activity and the calcining time is inversely proportional to the calcination temperature
