Crushing and Sieving. Once the sample has been crushed, it can be sieved to obtain the correct grain sizes. After sieving the sample is bagged according to grain size, usually resulting in three classifications; >.5mm, .25mm-.5mm, and <.25mm. Each bag is labeled with the sample name and grain size.
