 This is a machine working on concept of density classifier: separator. This has double deck to use as Classifier.This is mainly used to separate heavy particles from   the stream of wheat like stones, glass, metal etc.It give effects to cleaning of wheat stream in three ways. (1) Seperating the heavy materials from the stream ; (2) classifying the cleaned stream to allow    to go for further process directly without taking the same to other separators/cleaners, and (3) aspirating   the lighter particles from the stream through air duct connection which remains connected at the top of the machine making a fluidised effect of the wheat   stream over the destoner net.
