Calculating your grain fineness number. - Free Online Library

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.

Degermed Corn grits is the food prepared from fully mature, sound, degermed, kernels of maize (corn), Zea mays L., cleaned from impurities, mould, seeds of weeds and other cereals, by a grinding process in which the grain is comminuted to a suitable degree of fineness and from which bran and germ are almost completely removed.

Fineness Modulus Of Manufactured Sand - cookprocessor.eu

Fineness modulus of sand (fine aggregate) is an index number which represents the mean size of the particles in sand. It is calculated by performing sieve analysis with standard sieves. The cumulative percentage retained on each sieve is added and subtracted by 100 gives the value of fineness modulus.
