Influencing factors of calcination. 2. Granularity of Limestone The calcination speed of limestone depends on the particle size of limestone. The larger the particle size, the slower the calcination speed. Calcium carbonate in limestone is decomposed layer by layer from the surface to the inside. The thermal conductivity of lime is smaller than ...
