Cement raw material blasted in the quarry, requires size reduction for further processing. Size reduction is performed in crushers and grinding mills. Crushing is comminution in the coarse range, whereas grinding refers to comminution in the fine range. The technique of size reduction was developed chiefly by empirical analysis.
