Separator used to separate grain from pieces of dust, straw etc.
Separator consists of two parts:
Upper sieve part : Separates grain from big foreign parts and let them out
Lower sieve part : Separates grain from little parts that is passed from the upper sieve.  Parts of both sieves can be put out and in very easily.
