Mesh Number Solution

STEP 0: Pre-Calculation Summary
Formula Used
Mesh Number = 1/(Aperture Size+Diameter Of Wire)
m = 1/(w+d)
This formula uses 3 Variables
Variables Used
Mesh Number - (Measured in 1 per Meter) - Mesh Number is the number of open slots per linear inch.
Aperture Size - (Measured in Meter) - Aperture Size is the minimum clear space between the edge of opening in a screen.
Diameter Of Wire - (Measured in Meter) - Diameter Of Wire is a straight line passing from side to side through the center of the wire we are interested in.
STEP 1: Convert Input(s) to Base Unit
Aperture Size: 5 Centimeter --> 0.05 Meter (Check conversion here)
Diameter Of Wire: 3 Centimeter --> 0.03 Meter (Check conversion here)
STEP 2: Evaluate Formula
Substituting Input Values in Formula
m = 1/(w+d) --> 1/(0.05+0.03)
Evaluating ... ...
m = 12.5
STEP 3: Convert Result to Output's Unit
12.5 1 per Meter -->0.125 1 per Centimeter (Check conversion here)
FINAL ANSWER
0.125 1 per Centimeter <-- Mesh Number
(Calculation completed in 00.004 seconds)

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)

Mesh Number Formula

Mesh Number = 1/(Aperture Size+Diameter Of Wire)
m = 1/(w+d)

What are Grizzly screens?

Grizzly screens use a series of cascading grizzly bars or “fingers” to turn over material (for more efficient screening) and separate the material by size into course “overs” that feed across the screen and fines, or “through's”, that fall between the fingers.

How to Calculate Mesh Number?

Mesh Number calculator uses Mesh Number = 1/(Aperture Size+Diameter Of Wire) to calculate the Mesh Number, Mesh Number is the number of open slots per linear inch eg - 30 mesh screen means 1 inch consists of 30 openings . Mesh Number is denoted by m symbol.

How to calculate Mesh Number using this online calculator? To use this online calculator for Mesh Number, enter Aperture Size (w) & Diameter Of Wire (d) and hit the calculate button. Here is how the Mesh Number calculation can be explained with given input values -> 0.00125 = 1/(0.05+0.03).

FAQ

What is Mesh Number?
Mesh Number is the number of open slots per linear inch eg - 30 mesh screen means 1 inch consists of 30 openings and is represented as m = 1/(w+d) or Mesh Number = 1/(Aperture Size+Diameter Of Wire). Aperture Size is the minimum clear space between the edge of opening in a screen & Diameter Of Wire is a straight line passing from side to side through the center of the wire we are interested in.
How to calculate Mesh Number?
Mesh Number is the number of open slots per linear inch eg - 30 mesh screen means 1 inch consists of 30 openings is calculated using Mesh Number = 1/(Aperture Size+Diameter Of Wire). To calculate Mesh Number, you need Aperture Size (w) & Diameter Of Wire (d). With our tool, you need to enter the respective value for Aperture Size & Diameter Of Wire and hit the calculate button. You can also select the units (if any) for Input(s) and the Output as well.
