## Screen Effectiveness Based on Oversize Material From Overall Efficiency Solution

STEP 0: Pre-Calculation Summary
Formula Used
Screen Effectiveness Based on Oversize Material = Combined Overall Efficiency/Screen Effectiveness Based On Undersize
EA = E/EB
This formula uses 3 Variables
Variables Used
Screen Effectiveness Based on Oversize Material - The Screen Effectiveness based on oversize material is the ratio of the amount of oversized material A that is actually in the overflow to the amount of oversize material A in the feed.
Combined Overall Efficiency - Combined Overall Efficiency is the total efficiency of the feed that is the combined efficiency of the overflow feed and the underflow feed .
Screen Effectiveness Based On Undersize - Screen Effectiveness Based On Undersize is a measure of success of the screen in closely separating oversize materials.
STEP 1: Convert Input(s) to Base Unit
Combined Overall Efficiency: 10 --> No Conversion Required
Screen Effectiveness Based On Undersize: 0.6 --> No Conversion Required
STEP 2: Evaluate Formula
Substituting Input Values in Formula
EA = E/EB --> 10/0.6
Evaluating ... ...
EA = 16.6666666666667
STEP 3: Convert Result to Output's Unit
16.6666666666667 --> No Conversion Required
16.6666666666667 <-- Screen Effectiveness Based on Oversize Material

Combined Overall Efficiency of the Screen
Combined Overall Efficiency = (Mass Flow Rate of Underflow*Mass Flow Rate of Overflow*Mass Fraction of Material A in Overflow*(1-Mass Fraction of Material A in Underflow))/(Mass Flow Rate of Feed*Mass Flow Rate of Feed*Mass Fraction of Material A in Feed*(1-Mass Fraction of Material A in Feed)) Go
Mass Fraction of Material in Underflow
Mass Fraction of Material A in Underflow = Mass Fraction of Material A in Overflow-((Mass Fraction of Material A in Overflow-Mass Fraction of Material A in Feed)*(Mass Flow Rate of Feed/Mass Flow Rate of Underflow)) Go
Mass Flow Rate Of Under flow
Mass Flow Rate of Underflow = Mass Flow Rate of Feed*((Mass Fraction of Material A in Overflow-Mass Fraction of Material A in Feed)/(Mass Fraction of Material A in Overflow-Mass Fraction of Material A in Underflow)) Go
Mass Flow Rate of Over Flow
Mass Flow Rate of Overflow = Mass Flow Rate of Feed*((Mass Fraction of Material A in Feed-Mass Fraction of Material A in Underflow)/(Mass Fraction of Material A in Overflow-Mass Fraction of Material A in Underflow)) Go
Mass Fraction of Material in Feed
Mass Fraction of Material A in Feed = (Mass Flow Rate of Overflow/Mass Flow Rate of Feed)*(Mass Fraction of Material A in Overflow-Mass Fraction of Material A in Underflow)+Mass Fraction of Material A in Underflow Go
Screen Effectiveness Based On Undersize Material
Screen Effectiveness Based On Undersize = (Mass Flow Rate of Underflow*(1-Mass Fraction of Material A in Underflow))/(Mass Flow Rate of Feed*(1-Mass Fraction of Material A in Feed)) Go
Screen Effectiveness Based on Oversize Material
Screen Effectiveness = (Mass Fraction of Material A in Overflow*Mass Flow Rate of Overflow)/(Mass Flow Rate of Feed*Mass Fraction of Material A in Feed) Go
Mass Flow Rate Of Feed
Mass Flow Rate of Feed = Mass Flow Rate of Underflow+Mass Flow Rate of Overflow Go
Aperture Size
Aperture Size = (1/Mesh Number)-Diameter Of Wire Go
Mesh Number
Mesh Number = 1/(Aperture Size+Diameter Of Wire) Go
