Normally, for a size class i bounded between two successive screens x i and x i1 con-taining a mass fraction it at time m t, it is ...
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. If in special

Jun 23, 2020 This dead zone leads not only to a higher residence time of the average particle in the mill, but also a larger variation in the residence time. Pilot tests indicate that the residence time distribution of an overflow mill has a range up to 3-4 times that of a grate discharge mill, depending on mill operating conditions.
