In general, cement raw materials are mainly quarried, and so contain a certain amount of natural moisture. Attempting to grind a wet material is unsuccessful because an intractable "mud" forms. On the other hand, it is much easier to dry a fine material than a coarse one, because large particles hold moisture deep in their structure.

2012-6-18 · upon the nature and amount of fines in the ore as well as their moisture content. Drying the ore will certainly eliminate the sticky nature of the ore, but the fines con-taining high gangue will get into the coarse fractions, going to the blast-furnace. Drying is in no way cheaper than washing and wet screening with its distinct advan-tages.
