Question

what material passes through the holes of the sieve?why?​

Answer 1

The aggregate should be oven-dried at high temperature before sieving to prevent lump formation of the fine particles due to moisture content, which might clog the fine sieve holes.

Answer 2

The fine particles passes through the holes of the sieve because the bigger size particles cannot enter into the holes.

Explanation:

• The separation technique that is used based on the size of the particle is called sieving.
• The flour can be separated from impurities using sieving technique.
• To separate the flour from impurities the sieve plates are used.
• The fine particles are passed through holes of the sieve by using the sieve plates.
• Since the size of the hole is small, the big particles remains in the sieve.
