Requirements
NumParallelUnits	Input	The number of parallel, identical units to simulate: Feed is divided by the number of parallel units before being sent to the unit model. Unit model product is multiplied back by the same value and returned to the SysCAD product stream. All unit model result values are shown per parallel unit.
MediaStringsP50	CheckBox	Only visible if the MediaStrings option is checked. Replaces the MediaSize.Sim user defined value with the MediaSize (All) P50 value from the MediaStrings page. The value of MediaSize.Orig should be determined on the same basis for correct scaling of a changed media charge.
Stirred
UserExponents	Checkbox	Indicates whether to use user-defined values for the scaling exponents.
MillDiameter	Input	The inside liner diameter of the simulated mill.
MillHeight	Input	The height of the simulated mill.
MediaHeight	Input	Height of the media charge of the original and simulated mills.
MediaDiameter	Input	Median diameter of the media in the original and simulated mills.
StirrerDiameter	Input	Diameter of the stirrers of the original and simulated mills.
StirrerSpeed	Input	Rotational speed of the stirrers of the original and simulated mills.
StirrerStarts	Input	Number of starts of the (screw) stirrers of the original and simulated mills.
StirrerTurns	Input	Number of turns per start of the (screw) stirrers of the original and simulated mills.
WorkIndex	Input	Bond Ball Work Index of ore in the original mill.
Exponent	Input	Only visible if UserExponents is selected Allows user to specify values of the scaling exponent for each original/simulated parameter pair.
R/DFunction
NumSplineKnots	Input	Number of spline knots for the $R_{i}/D_{i}^{*}$ function.
Size	Input	Spline knot size positions.
Ln(R/D*)	Input	Values of $\ln R/D^{*}$ at each spline knot position.
Results
MillVolume	Display	Volume inside the mill.
MediaVolume	Display	Volume occupied by the media in the mill, excluding void space.
SlurryVolume	Display	Volume of slurry in the mill, including slurry in media void space and above media charge.
LoadFraction	Display	Volume of media charge, including void space and excluding stirrer volume, as a fraction of mill volume, excluding stirrer volume.
ResidenceTime	Display	Mean residence time of slurry in the mill.
