how can you separate sand and gravel?

Answer 1

use a filter with squares (a mesh) about 2mm apart, sand will fall through, gravel will be trapped,

You will have to shake it periodically to get the sand going through, but it should work

hope this helps

Answer 2

Separating Sand And Gravel

Answer 3

This depends upon how you define these two items. If sand is the smaller partical when compared to the gravel that it's mixed with then, yes, separating them is easy.

Find a material that has perferations (holes) that are larger than the largest sand partical but smaller than the smallest gravel partical. A window screen would probably work well.

Create a small wooden frame and staple the screen material to one side. Then put the mixture in the frame and shake it.. the sand will fall out.. the gravel will stay in.

Good luck!

Answer 4

Particles differ in size. Thus, I would use a colander u other sieve with a mesh fine enough to let the sand through but not the gravel.

Answer 5

To seperate gravel from dirt you need wood nails and a sturdy piece of mesh.

first:

Take wood hammer them together to make a square. When that is done add to more piece of wood to make it standing up. After that staple one piece of mesh to the sqaur side of the mesh. And then dumb sand and gravle onto it.

You can also make it like a table and dump dirft ontop.

Anyways Good LUCk!!

Answer 6

give it some medium degree of vibration inside containner. The sands will sink to the bottom and the gravels will be on top.

You have to do it gently and longer time.

Answer 7

Screen it through a wire mesh.
