The formula for calculating critical mill of speed: N c = / √ (D d) Where: N c = Critical Speed of Mill. D = Mill Diameter. d = Diameter of Balls. Let's solve an example; Find the critical speed of mill when the mill diameter is 12 and the diameter of balls is 6. This implies that;
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 (LID) ratios, the mean residence times of solid were also determined from measured mill holdups.
