Mechanical screening - Wikipedia

Screening falls under two general categories: dry screening, and wet screening. From these categories, screening separates a flow of material into grades, these grades are then either further processed to an intermediary product or a finished product. Additionally, the machines can be categorized into a moving screen and static screen machines, as well as by whether the screens are horizontal or inclined. MARC Technologies » Wet Screening, Wet Washing or De,,6. Test Sieve Grade ISO 3310-1 Woven Wire Mesh Sweco or Kason Separator Replacement Decks . Most decks used on this class of equipment use industrial wire screen grade mesh (ISO 4783-1) and not test sieve grade (ISO 3310-1). This means that laboratory sizing results derived from a Sweco or Kason (or other) would not pass a quality audit.Dry and Wet Screening in Mining: What are the Differences,,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. A water separation system does not allow dust to fry flee and choke the equipment.
