Lime Rotary Kiln - gwmcn
The lime rotary kiln is with advanced structure. Its pre-heater with low-pressure loss can improve preheating effect efficiently. After preheating, the resolution ratio of the lime-stones can reach 20~25% when they enter the kiln. Besides, the lime-stones, with fine fraction about 10~15mm, can be used directly. 2.Waste Heat be Reused Effectively
Lime kiln - Wikipedia
May 02, 2013· Calcining kilns need limestone with proper decrepitation index. Decrepitation index of limestone is a measure of its susceptibility to disintegration during calcination. Low value of decrepitation decreases the porosity of the bed thus impeding the flow of the gases the kiln efficiency. Rotary kilns also need limestone with good tumbling index.
