Re: main aim of sieve 63,100,200 for raw material
but , if the matter of sieving on 63 , 100 , 200 depend on particle size distribution - why i donot use for example sieve 45 micron and we use in our raw mill control sieve 90 and 212 micron so why the range from 63 to 212 micron ( mean why we use only this range in raw material )
with consideration that in cement grinding we use 45micron and maybe 32micron and in open circute mills used 60 micron to know the resuide which reflect the unreacted material in cement

Cement is ground finer than kiln feed. That is why different sieve sizes are used for the different materials. To give a meaningful residue.
