Grain Fineness Number Industrial Appratus
2019-8-17 The optimal grain fineness number GFN in a sand system is determined by the type of metal poured, pouring temperatures, casting product mix heavy vs. light castings and required surface finish. Once that optimal fineness level is determined, maintaining a consistent grain structure becomes a critical factor in the quality of the final castings

Grain Fineness Number Engineering Dictionary EngNet
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. It is approximately proportional to the surface area per unit of weight of sand, exclusive of clay.

Calculating your grain fineness number. Free Online Library
2009-12-1 The grain fineness of molding sand is measured using a test called sieve analysis, which is performed as follows: 1. A representative sample of the sand is dried and weighed, then passed through a series of progressively finer sieves (screens) while they are agitated and tapped for a 15-minute test cycle. 2.
