Sieving is a method of separating particles based on size using a sieve or meshed device. It’s used in cooking to sift flour or sugar, in construction to filter aggregates for concrete, and in pharmaceuticals to obtain uniform-sized particles for medicines. Laboratories use sieves in chemistry experiments to separate particles based on size or composition, aiding in various industries and applications.
Sieving is the process of filtering components of a mixture of different sizes. Sieving allows fine particles to pass through the holes of the sieve, while the bigger impurities remain on the sieve.
Sieving is used in flour mills to separate broken particles of grains from flour. It is also used at construction sites to separate lumps, smaller stones from the mixture of sand and cement.
