Best Practices for Dust Control in Metal/Nonmetal Mining
The intent is to have the droplets collide and attach themselves to the dust particles, causing them to fall from the air. In these cases, droplets in the range of 10 to 50 microns have been shown to be most effective [Bartell and Jett 2005]. Uniformity of wetting is also a very important issue for an effective system.
