cement mill retention time

Cement Mill Retention Time

Cement grinding Vertical roller mills versus ball mills. 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
