  • Classifier Nova Mining

    Jun 25, 2014 it is desired to reduce, in stages, the surface velocity of the fluid flowing from one vessel to the next. The greatest use for hydraulic classifiers in the mineral industry is for sorting the feed to certain gravity concentration processes so that the size effect can be suppressed and the density effect is enhanced.
