    You now have the unit capacity. Then take the volumetric feed rate of the new ore per time. Divide the unit capacity by the feed rate and you have the nominal retention time. Say your unit capacity is 1/2 cubic meter and you are feeding 6 cubic meters per hour your retention time would be about 5 minutes.

  • 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 may not be a problem if the gypsum is sufficiently
