Grinding in Ball Mills Modeling and Process Control

The design of a ball mill can vary significantly depending on the size, the equipment used to load the starting material feeders , and the system for discharging the output product The size of a mill is usually characterized by the ratio length to diameter and this ratio most frequently varies from 05 to 35 The...

The length to diameter ratio of cylindrical mills range from 1 to 1 through 3 to 1 When the L/D 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 ....
