The reason closed circuit grinding mills have not succeeded (Soviet cement experts substantiate) is as follows: ... The tendency to agglomeration causes difficulties when grinding cement clinker in open circuit to higher specific surfaces than Blaine [143a]. For fine grinding in open circuit, the F. L. Co, developed a grinding ...

Within this study effect of open and closed circuit HPGR applications on dry grinding circuit performance was examined. For this purpose sampling studies around three different cement grinding circuit were completed. In the first study, a circuit including open circuit HPGR, ball mill and air separator was sampled and chosen as the basic condition.
