Calculating your grain fineness number.

 · 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 that could lead to potential casting problems.
