Abstract:

This paper analyzed the status of lime production in china and stated the technology ideas and advantages of lime powder suspended calcining process.It pointed out that the heat exchange rate is high when preheating,decomposing and cooling in suspension state;calcium carbonate powder decompose with high rate and high degree; suspension calcinator with uniform and controlled temperature can improve products quality stability.This process increased high quality resource utilization rate,because lime stone with different sizes can be milled into powder as raw material.
