Fisher Sub-sieve Size image


Fisher Sub-sieve Size is shorted to F.S.S.S., which is a grain size mode representation by air passing method. The principle is to test the specific surface area and average grain size under stable air passing and pressure. When use this method to test the grain size, there should be many samples in order to test the average grain size.

Testing Equipment

Fisher Sub-seive Sizer is the testing machine to test the grain size.
