Although such information contains long lists of sieve sizes in practice sieves are normally used in series in which each member sieve is selected to pass particles approximately 1 √2 or 1 2 smaller in size than the previous sieve For example the series 80mm 63 40 31 5 20 16 14 10 8 nbsp

A sieve analysis or gradation test is a practice or procedure used to assess the particle size The size of the average particle on each sieve is then analysed to get a cut off point or specific size range which is then captured on a screen
