Question

Gravel and sand after being delivered.

Why is there a need to seperate? ​

Answer 1

Explanation:

the reason for us, is to easily utilized the materials (sand and gravel). like for example in plastering it is easy to use the fine sand without putting so much manpower on it after being separated from gravel. Likewise in gravel, you dont need so much manpower when it's already separated from sand.
