Grain size of limestone 1 In the process of calcination, the granularity of the raw limestone affects the whole process a lot. Since the separation of CO2 proceeds slowly from the surface of the limestone to the inside, the calcination of large particle size is more difficult than that of small ones, and it takes a longer time.
