About this document
AFS Grain Fineness Number Analysis by Usman Gujjar is a document available to read on EtoBox.
The document is a lab report that determines the AFS grain fineness number of foundry sand. It describes using a sieve shaker to separate 500g of dried river sand by mesh size. The percentage of sand retained on each sieve was recorded and used to calculate the AFS number, which was 66.48, using the formula that divides the total product of percentages by the total retained weight. This number approximates the mesh size that the average sand grain could pass through.
