WET DUST SUPPRESSION - Air/Water or just Water
(OP)
I am investigating Wet Dust Suppression applications for mineral mining (gold,zinc,lead etc). Does anyone have experience with High Pressure Water Fogging? How does it compare to the lower pressure air/water combination approach. Our system is upstream of a floation circuit and thus we need to be carefull not to add chemicals that will affect this circuit. Alos, we are trying to keep water consuption minimal do to the site location. I have talked to proffesionals who have used the compressed air/water combination and have had positive feed back. However, in my readings I have discover that high pressure water fogging is "potentioally" better since it keeps air velocities down, doesn't require air compressor, only needs simple filtration system and is more energy efficient. If anyone has experience with these applications please comment!

Thanks for you info however, I should have made my application more clear. I am hoping to use fogging for conveyor transfer points. Do you have any experience with this?

A fogger of good design will work for your product very well.Set it or them above and below where dust extraction is the greatest for maximum effect

I once used a water-spray system on the dry circuit of our gravel crushing plant (terribly dusty) had a 7 nozzle assembly under the cone crusher and 2 or 3 nozzles at each transfer point. (6 total) At some transfer points we sprayed both sides of the aggregate stream to get effective control. If I recall correctly, the nozzles used about .25 gpm each, The water usage was about 100 gal / hr for about 2 gal / ton. The water pressure was about 120 psi
It was extremely hot and windy on this particular job that we used dust control on....the benefit was not only in the working conditions and overall site cleanliness but in the lowered maintenace costs for the equipment....particularly air filters
Here's a good link: ht
Dust control is also about air control, falling agregate creates it's own wind that's what initially gets the dust airborne....control that and half the dust problem is controlled too.
