spray water in coal crushers

NESCO Dust Control Equipment, Water Spray / Wet Suppression .Improves dust control on hard to wet materials like coal or petroleum coke. NESCO can also build Foam Systems that use water, compressed air, and chemical agent to make a low-expansion foam that controls emissions from crushers and transfer points. Unlike chemical vendors that lock a customer into their chemical,.spray water in coal crushers,The Science of Coal Dust Suppression - Parker Hannifinalso not practical underground. An ideal solution is one that can make use of a mine's existing water supply in the form of a spray to suppress the dust, ideally as soon as the dust is generated at the coal extraction point, as well as at all other subsequent points where dust can be generated – crushers, belt transfer points, etc.

Effects of atomization parameters of dust removal nozzles on the de .

The dust characteristics from different mines and atomization parameters of different pressure nozzles were measured. It was found that the internal pressure of coal cutters and roadheaders should be kept at 2 MPa, which could ensure large droplet size, large spraying angle and low water consumption and hence realizing.
