why in a mixture of different size same density steel balls we have a separation when shaken?

I searched on "Brazil Nut Effect" in quotes and got 179,000 hits.

Yes they can. If you have a mixture of large and small particles, the small one can fall in between the big ones every time the mixture is shaken, and take small steps toward the bottom. On the other hand, the big one cannot fall through spaces between little ones. It is very hard for the big ones to push small ones up.crx said:and nobody can explain the reason why small particles get at the bottom!
Separation of steel balls in a mixture is the process of separating different sizes and densities of steel balls from a mixture using various techniques such as sieving, magnetic separation, or density-based separation methods.
Understanding particle size and density is important because it helps determine the most efficient method for separating the steel balls in a mixture. Different methods are more effective for different particle sizes and densities, so knowing this information can save time and resources.
Some common techniques for separating steel balls in a mixture include sieving, magnetic separation, and density-based separation methods. Sieving is used for separating particles based on size, while magnetic separation uses a magnet to attract and separate steel balls with high magnetic properties. Density-based separation methods use differences in density to separate particles.
The efficiency of separation in this process can be affected by several factors, including the size and density of the steel balls, the type of mixture, the method used for separation, and the equipment and conditions used for the separation process.
Some potential challenges or limitations in separating steel balls in a mixture include the presence of other materials in the mixture that may interfere with the separation process, variations in particle size and density within the mixture, and the need for specialized equipment and techniques for efficient separation.
