## Calculating your grain fineness number. - Free Online

2009-12-1 The AFS Grain Fineness Number (AFS-GFN) is one means of measuring the grain fineness of a sand system. GFN is a measure of the average size of the particles (or grains) in a sand sample. AFS-GFN gives the metalcasting facility a means to verify its molding sand is staying within specification for the castings being produced and avoid conditions ...

## Grain Fineness Number Calculator Fineness Modulus

Grain Fineness Number Calculator What Is Grain Fineness Number. A system developed by AFS for rapidly expressing the average grain size of a given sand. It approximates the number of meshes per inch of that sieve that would just pass the sample if its grains of uniform size.

Two tests will be performed in this module: the AFS 1105-12-S: Sieve Analysis (Particle Determination of Sand) and the AFS 1106-12-S: Grain Fineness Number, AFS GFN, Calculation tests. Topics that will be covered: purpose of the tests, basic variables that factor into the tests, and performing the tests in a virtual environment.

## Molding Sand - Knowledge Base - Applications

Foundry sands usually have a size distribution from 0,1 mm – 0,8 mm with a mean size between 0,2 mm and 0,45 mm. A standard parameter to express the size of molding sands is the AFS fineness number (AFS = American Foundry Society). This number is calculated from the size distribution, which is determined by standard ASTM sieves.
