The raw PG is a kind of paste with a high water content. If the wet PG is fed into the cement mill, the feed inlet of the cement mill will be chokedup frequently, so the quantity of PG can't be measured accurately enough. Therefore, the raw PG needs to be dried before it is fed into the cement mill as a cement retarder.
