what si Sieving

Sieving is another method used to separate particles of different sizes. In this method, the mixture is passed through a sieve or mesh.

The smaller particles pass through the holes of the sieve, while the larger particles remain on the sieve.

Sieving is used in many situations such as:

• Removing stones and husk from wheat
• Separating pebbles from sand
• Separating bran from flour in flour mills

Thus, sieving works on the basis of difference in particle size.
