Cement Grinding Vertical Roller Mills Versus Ball Mills. OK mill and the retention time in the mill is shorter, the product will not be heated up as much as in a ball mill. this means that a lower degree of dehydration of the gypsum must be anticipated. this may not be a problem if the gypsum is sufficiently reactive to control the setting reactions, which is normally the case.
