As the watery stream circulates, centrifugal force splits the water from the finely ground mineral aggregate. Cyclonic scrubbers and spiral mechanisms bend to the will of the slurry stream. Material slurries enter different screening solutions while dry screening mechanisms tend to stick to the tried and true flat deck configuration. Otherwise, the overly fine black dust would escape the screening equipment. For example, powdered coal requires a wet screening stage. Having said that, there comes a point when dry screening is no longer viable. Meanwhile, the wet “slurry” produced by the sprinkler nozzles necessitates a dewatering stage. Two deck models augment the process while keeping the cost of the equipment range manageable. Energetic impacts separate the material so that it can be sized and sorted. If the high-volume aggregate goes up, its mass will inevitably bring the fine grains down again. More economical by design, standard screening solutions rely on vibrational energy and gravity. A water separation system does not allow dust to fry flee and choke the equipment. Incidentally, dry screening lines produce large clouds of floating dust. 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. Wet screening systems add water to the mix. Some of these aperture-clogging chunks cannot pass through the screens, no matter how much oscillating motion is applied. There are chunks of dirt and clay on the deck bottom. The screening decks are using vibrational energy to separate precious minerals.

Fend off expenditure overheads by knowing the differences between dry and wet screening. Extra plant capital is on the agenda when these additional stages enter the equipment line. First of all, wet separation technology requires additional equipment, including the spray nozzles that funnel the water.

If you think the differences between dry and wet screen mining are limited to the presence or lack of water, then you’re missing several important points.
