2017421The length to diameter ratio of cylindrical mills range from 1 to 1 through 3 to 1. When the LD ratio is 2 to 1 or greater we refer to the mill as a Tube Mill. Trunnion overflow discharge A trunnion overflow mill has an open discharge end. Material flows through the trunnion as a result of the pulp gradient between the feed and discharge

On the other hand the fineness of the material at the mill outlet depends mainly on the retention time of the material in the mill. The main influencing factor on the retention time is the mill length. Therefore the ratio of length to diameter LD of a mill is an important factor for an optimal design of the mill.

Should be noted the productivity of ball mills depend on the drum diameter and ratio between the diameter and length of the drum. At the short ball mill grinding is a more rough and for grinding fineness a lot of material has to be returned from classifier to the mill it leads to mill overload.
