Chemical gypsum, if used instead of natural gypsum, needs to be dried either by natural sun drying or by mechanical drying, before it is used with cooled and dried clinker for inter - grinding in mills. In clinker grinding,gypsumbeing the more readily grindable, tends to be concentrated in the finer particle size fraction of the product.
