Combined Overall Efficiency of Screen

Go 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))

Mass Fraction of Material in Underflow

Go 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))

Mass Flow Rate of under flow

Go 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))

Mass Flow Rate of over flow

Go 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))

Mass Fraction of Material in Feed

Go 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

Screen Effectiveness based on Undersize Material

Go 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))

Screen Effectiveness Based on Oversize Material

Go 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)

Screen Effectiveness based on Oversize Material from Overall Efficiency

Go Screen Effectiveness Based on Oversize Material = Combined Overall Efficiency/Screen Effectiveness Based On Undersize

Mass Flow Rate of Feed

Go Mass Flow Rate of Feed = Mass Flow Rate of Underflow+Mass Flow Rate of Overflow

Diameter of Wire in Terms of Mesh Number

Go Diameter Of Wire = (1/Mesh Number)-Aperture Size

Aperture Size

Go Aperture Size = (1/Mesh Number)-Diameter Of Wire

Mesh Number

Go Mesh Number = 1/(Aperture Size+Diameter Of Wire)

Combined Overall Efficiency of Screen Formula

What is Revolving Screen?

A screen consisting of a cylindrical (sometimes conical) screening surface mounted on a revolving frame for sizing coarse material; it is still common in gravel-washing, coal-washing, and stone-treating plants, but is not widely used in ore dressing.

What is Working Principle of Ultra Fine Grinders?

Firstly, the wet material will be pumped into the grinding machine which is prepared with a certain amount of grinding mediums. Then, the driving part will drive the mixing parts to rotate in a high speed. Due to this, the wet materials and grinding mediums will also rotate at a high speed, thus the raw materials will be ground into ultrafine materials under the impact force, shearing force and collision force between grinding mediums.
