Terex has developed the Aquamist dust suppression system, an improvement over conventional jets or water-sprays. They are a high capacity misting fan which produces finely divided water droplets in the size range 10-150  micron diameter. At this size they can easily combine themselves with dust particles of similar dimensions and  precipitate them out of the air. Because water-mists “float”  more than a conventional spray it covers and envelops the  dust cloud more effectively.
