there are all types they have a drum sieve which is common in Asia, soil sieves and sand sieves.
Spatulas of differing shapes, ladles, stirring spoons, spoons with holes, sieves, scrapers are just a few of the common ones.

i think its good becuase if its som different marterial sizes
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

Classifier Sieves are available in many different "Mesh" Sizes. These sizes are based on the holes per square inch. A size 8 would have 8 holes per square inch, and a size 20 would have 20 holes per square inch. These are used to separate different sizes of dirt from each other. Different types of prospecting equipment processes different mesh sizes of dirt.

yes, different types of rock probably do make different types of glass
yes there are different types of gills in different types of fishes.
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.
