Many years of KOMAG experience in jigs designing and selection, enable to use them in aggregate industry, especially for gravel and sand winning with the separation of organic impurities. Technological studies of gravel and sand separation, conducted in laboratory conditions on a test stand and industrial studies carried out in selected mines which use technological systems based on beneficiation of raw coal in pulsating washery jigs, confirmed a purposefulness of use the designs proved in hard coal processing for gravel and sand production. The new generation of a jig of the KOMAG type (pulsating classifier) operating in aggregate mine in industrial condition was presented.
