  • MATERIAL RETENTION TIME IN A BALL MILL VRM

     · Re: MATERIAL RETENTION TIME IN A BALL MILL VRM. You could do that by measuring the material flowrate Q[tons/h] through the mill as well as the quantity M[tons] of material that accumulates within the mill. The retention time, also called residence time, is the ratio (M/Q) [h] .

  • Optimizing your SAG mill operation

     · The mill discharge from these mills consists of slurry, which goes to the ball mills for further grinding, and coarse pebbles/rocks, which are crushed and sent back to the mill. To maximize the capacity of these circuits, the general practice is to use grates with pebble ports (reaching 100 mm) instead of normal grate openings to increase the pebble removal.

  • Ball Mills Distributions

    Residence time distributions RTDs were estimated by water tracing in a number of wet overflow ball mills diameters to m producing dense, coalwater slurries. In opencircuit mills of m diameter and various lengthdiameter LD ratios, the mean residence times of solid were also determined from measured mill holdups.

    The average residence time of the ore in the mill is 30–60 seconds. There is negligible shortcircuiting of the grinding zone by the feed, as a result of having multiple grinding chambers in series. The ground product is separated from the grinding medium at the discharge end of the mill.
