Sieving is the process of separating particles based on their size using a sieve or mesh. The material to be sieved is poured onto the sieve, and then the sieve is agitated or tapped gently to allow smaller particles to pass through while larger particles are retained on top. This method is commonly used in industries such as food processing, agriculture, and pharmaceuticals for particle size analysis and separation.

What is difference between winnowing and sieving?
winnowing is the separation of solid-solid separated by size and weight whereas sieving is the separation solid-liquid judged by shape and size.
What is example of sieving?
An example of sieving is when you use a sieve or strainer to separate larger particles from smaller ones. For instance, sifting flour to remove lumps and break up clumps is a common example of sieving in cooking and baking.
What class of lever is sieving machine?
A sieving machine is typically considered a third-class lever, where the effort is placed between the load (material being sieved) and the fulcrum (pivot point). In this case, the effort is exerted by the machine to sift the material through the sieve.
How will you separate sand?
You can separate sand from other materials by using methods like sieving, sedimentation, and filtration. Sieving involves passing a mixture through a mesh or sieve to separate particles based on size. Sedimentation involves letting the sand settle to the bottom of a container of water, allowing you to pour off the water and collect the sand. Filtration uses a filter paper or mesh to separate the sand from a liquid mixture.
How would you use physical properties to separate sand from seashells?
One way to separate sand from seashells based on physical properties is to use their differences in density. Most shells are less dense than sand, so you could use a process like flotation or selective screening to separate the two. Another method could be sieving, where you use a sieve to separate the larger seashells from the finer sand particles based on size differences.
What is bigger rock or salt particles?
This depends on the grinding and sieving process.
What is the general name of a process by which tea leaves are separated from prepared tea?
sieving
What happens when sieving if the holes are too small?
If the holes are too small during sieving, it can lead to clogging and blockage of the sieve, reducing or preventing the passage of particles through it. This can affect the efficiency of the sieving process and may require manual intervention to clear the blockage.
What are the example sieving?
Examples: sieving of sand, sieving of flour, dimensional sorting of peas and beans, etc.
Is sieving sand from stones reversible?
Yes, sieving sand from stones is reversible because the process can be undone by mixing the sand and stones back together. This separation technique relies on differences in particle size, making it easy to separate and recombine the materials as needed.
Why A mixture can be separated by sieving but not by winnowing or handpicking give reason?
due to different size of particles during milling process
Under what conditions should you use wet sieving instead of dry sieving?
Wet sieving is typically used when the sample material is cohesive, contains fines, or when the particles are highly irregular in shape. It helps to overcome issues such as agglomeration, particle trapping, or size underestimation that can occur in dry sieving. Wet sieving is also useful when accurate particle size distribution data is needed for fine-grained materials.
What are the different physical separation process in separating mixtures?
Examples: filtration, decantation, distillation, sieving, magnetic separation, solvent extraction, etc.
Why do iodide table salt and kosher salt crystallize at different speeds and sizes?
This depends on the parameters of the crystallization process or the possible grinding and sieving.
Examples of sieving?
flour
What is difference between winnowing and sieving?
winnowing is the separation of solid-solid separated by size and weight whereas sieving is the separation solid-liquid judged by shape and size.
What rhymes with Thanksgving?
