Combined grinding technology of roller press was an organic combination of roller press and ball mill, which integrated the high-efficiency and energy-saving features of roller press and the wide particle grain size distribution, uniform particle group shape and good particle morphology of fine slag powder produced by ball mill. So fine slag powder produced by combined grinding technology had a higher admixture proportion than that produced by vertical mill or other grinding system. When producing fine slag powder with high specific surface area, the combined grinding was of high capacity and low energy consumption. Cement mixed with fine slag powder produced by combined grinding technology had higher strength in each age compared with that mixed with fine slag powder of the same specific surface area produced by vertical mill. So combined grinding should be the first choice, while the fine slag powder produced by it had a better awareness in market.
