Cement Grinding Percentage

An industrial comparative study of cement clinker grinding ...

2012-5-1  Table 2 also shows that the combined grinding cement has a relatively higher percentage (14.1%) of 45-μm residue than the cements produced in the other two grinding systems (7.6% and 9.3% for the HPRM-only and the horizontal roller mill system, respectively). The 45-μm residues of the ball mill cement and the HPRM cement in the combined ...

Characterization of various cement grinding aids and their ...

2009-5-1  When cement clinker is ground using grinding aids a narrower particle size range is generated, as the percentage of very fine particles, which only influence the setting time, is reduced. This is why the strengths at equal Blaine values are higher than when grinding without grinding aids.
