As less grinding energy is used in producing a cement of a required fineness in an 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.
