Crushing and Sieving Purdue University: Department of

Procedure. Select two sieves and clean them thoroughly with a brush and a dissecting needle. The goal is to eliminate polymineralic grains, so the coarser sieve should have openings somewhat smaller than the average crystal size in the rock. Use a 0.5 or 0.25 mm screen for the finer sieve. For coarse granite samples, I used 1.0 mm and 0.25 mm

Soil Sample Preparation and Extraction

Recommended Method for Crushing and Sieving Soils Because soil is defined as having a particle size of less than 2 mm, this sieve size (10 mesh) is recommended for routine soil testing. Various soil grinders and crushers are available commercially and are typically large, motorized, mortar and pestles, hammer-mills, or roller-crushers.
