This appearance is because the vertical-roller-milled slag powder is refined by a grinding roller through squeezing and shear and only stays in the mill for a very short time. Thus, the powder particles exhibit a more irregular morphology. Download : Download high-res image (443KB) Download : Download full-size image; Fig. 5.
