Raw data was taken from old notes, a curve was fitted to the data to determine general characteristics.This was then used to calculate curves for each device based on separating gavity and assumed Ep.Ep: From empiracal data a method using a unique formula for each device Ep =F1*F2*(F3*SG-F4)

F1: Where F1 is calculated from the SG and the Ave Size

Ave SizeF2: Prediction or guarantee, 1.0 if predicting performance, 1.25 if guaranteeing performanceF3: empirical factors determined by testing and unique for each equipment (generally)F4: empirical factors determined by testing and unique for each equipment (generally)

The actual equipment curves are calculated from normalized curves upon which a regressionanalysis was run. This curve is then used to calculate a unique curve from the input data.

AlternativelyEp: Ep is an abbreviation for Ecart Probable Error and is a measure of the precision of separation.

It is defined as the specific gravity at which 25% of the feed reports to clean coal (D25), minus the specific gravity at which 75% reports to clean coal (D75), all divided by 2, or: Ep = (D25 - D75)/ 2

Ave Size If the product is closely sized, average size may be takeen as the arithmetic mean of the top and bottom sizes. For 65 M x 100 M : Ave. Grain Size = (0.212 + 0.15)/ 2 = 0.181 mmIn dealing with a wide size range or unsized coal more precision is needed.The best average uses the specific surface area of the average size particle. This equals the specific surface area of the sample. For a given size distribution the average size is then: Ave. size = 100 / (sum(f/x for x = 1 to N)) f = volume abundance for each size (% wt. x 600/x size (mm))Calculating the surface area requires a great deal of information that may not be available.

Work is based on data from Process Performance Spreadsheet
