Sieving is a method of using a sieve to distinguish small particles from bigger particles. It is used in flour mills or building sites. Impurities such as husks and stones are extracted from wheat at flour mill. They remove pebbles and stones from sand through sieving.

After crushing, we transferred the crushed sample into a modified Casagrande apparatus (Mennerich Geotechnik, Hannover, Germany), consisting of three sieves that rest on a collecting vessel. Here, the sample was exposed to the purely mechanical forces of repeated tap-sieving cycles at a frequency of 2 Hz.

The term ‘sieving’ describes the separation of undesirable fine and coarse particles. For sieving, a vibration sieve is typically used. For homogenizing granules, we use grinders that work according to the principle of rotor sieves for homogenization. Coarse particles are reduced to the desired size. Rotor sieves for homogenization are used

Sizing a crusher can be done reliably calculated thanks to the Impact/Crushing Work Index and the testwork research done by Fred Chester Bond and his 1952 paper. According to Bond ’s Third Theory of Comminution , the work/energy input is proportional to the new crack tip length created during particle breakage and equivalent to the work represented by the product – the feed.

With most particles going through a 3/8-inch sieve, fine aggregates typically consist of natural sand or crushed stone. All particles larger than 0.19 inches are coarse aggregates but usually vary between 3/8 and 1.5 inches in diameter. Gravels make up much of the remaining coarse aggregate used in concrete with crushed stone.
