Optimization Practice of Production Process Adjustment of Cement Grinding System under New Standard
GAO Wenfeng
Abstract：This paper compares and summarizes the main revision contents of the new standard GB175-2023"General Portland Cement",aiming at the problem that the fineness of 45μm sieve of finished cement in some enterprises does not meet the requirements of the new standard,several technical improvement measures are put forward,and taking the semi-final grinding system of"roller press+ball mill"in a production line as an example,the technical improvement scheme of"material processing in different paths+partial separate grinding"is put forward.After adjusting the lining plate and activation ring of the ball mill,optimizing the grading of the grinding media and introducing coarse-grained mixed materials,the residue of the 45μm sieve of the cement finished product was stabilized at about 7%,which realized the compliance production under the new standard and provided a new path for the technical upgrading of similar production lines.
