Feb 14, 2018 Left to screen coarser ore currents, the dry screening method is still the more economical solution. Adding a series of nozzles and pipes, fluid separation plants are more costly, but that cost is warranted, for its recovered as the clay and mud deposits dissolve.
Wet screening systems add water to the mix. Granted, the additional pipes and spray nozzles cost more than a dry screening system, but that cost is quickly accounted for as the clay is washed away. Incidentally, dry screening lines produce large clouds of floating dust. Online Chat Difference Between Dry And Wet Iron Ore

Jun 20, 2016 A-Z Guide to Screening Ore, Rock Aggregate. A simple definition of a screen is a machine with surface (s) used to classify materials by size. Screening is defined as The mechanical process which accomplishes a division of particles on the basis of size and their acceptance or rejection by a screening surface.
Jun 10, 2016 Screening is the passing of material through definite and uniform apertures is the only true and accurate means of grading to a required particle size. Air separation and hydraulic classification depend upon gravity and particle shape, and result in the segregation and retention of material of higher specific gravity and lower surface area irrespective of size.
