Sieving is used in construction sites to filter large rocks and other particles from the sand particles. It is used to separate churned flour and raw wheat in flour mills. It is also used to remove husk and stone impurities from wheat and rice. We hope this article has helped the readers understand the topic of Sieving.

Some examples of sieves are shown in Fig. 8.1, together with the logos/names of the major manufacturers of sieves. Sieving is practically the only method for size analysis of particles larger than a few millimeters. Sieves are easy to use from a cut size in the cm range down to about 50 μm; with due care they can be used down to about 5 μm.
