I believe it describes snow as 'an equalizing and leveling power on the world'. If you want to know how I got this answer, I read it in my literature lesson for school. !
The opening lines of Emily Dickinson's poem "It sifts from Leaden Sieves" describe snow as gently falling from the sky like sifted powder through a sieve. The imagery conveys the delicate and slow descent of snowflakes.
there are all types they have a drum sieve which is common in Asia, soil sieves and sand sieves.
sieves work by having holes on the bottom and all the dirt and water goes through and leaves the gold
with a set of sieves

You think probable to the separation with molecular sieves.
The size of the holes in a sieve depends on what is the the size of material to be allowed through the holes. A set of sieves (flour sieves, garden riddles, etc) will range from large holes to fine.
One that is free of water. Usually distilled and stored with molecular sieves/MgSo4

Meshes and sand sieves are used to separate insoluble (non dissolvable) particles from contaminated water (eg. lake, sea water) in preparation for further treatment. An answer by a 13 year old girl :)

I am gald to help you,my friend . The electric motor makes the driver eccentric cause high speed revolving through triangle belt, The revolution eccentric has the very big centrifugal force, which stimulates sieves box to have circularmotion with certain oscillation amplitude. The materials on sieves receive the impulse which the sieves passing to produce continual throwing movement in the inclined screening surface, in the process of the material and the screening surface meeting ,it makes the pellet which is smaller than the mesh pass sieves, thus realizes the graduation.. Its law of motion is the circular or the ellipse line, the vibration source is the driver leading for the electric motor. The circular oscillation sieves is the single axle vibrator, the main axle fixed in sieves box makes fast revolving by the electrical machinery, the eccentric body installed on main axle makes rotation along with it, and causes the centrifugal force of inertia,which makes the sieve box that can have free vibration have the approximate circular trace's vibration.
