11/12/2019Calcified slag without wet grinding was used for comparison. The results of the particle size distribution showed that the large particles decreased significantly with the ground calcified slag (Fig. 6a and b). In the wet grinding process, the breakage rate of large particles was higher than that of fine particles for two reasons.
