For open dump pockets we sometimes require a DustTamer Wind Screen to reduce the effects of wind and displaced air caused by the dump. This shields the dump pocket from ambient wind and increases fog and dust retention time.
Dry Fog is designed to only agglomerate to airborne dust, not wet the material being handled. Typical moisture addition to the material is less than 0.05%. It has been estimated that our nozzle design can create enough fog to cover the area of 1/2 a football field with One Gallon of Water!
Because Dry Fog is designed to treat only the airborne dust using microns sized droplets, very little moisture addition takes place, so there is little if any Carry Over Effect. Dry Fog is injected into each point of dust creation similar to a bag-house collection system.
With Dr Fog, no chemicals are used. Chemical systems can have a Damaging Effect (see article) on conveyor belts. Surfactants are designed to break up the surface tension of the water droplet to increase its distribution into the material. Dry Fog produces microscopic droplets that collide with airborne particles and have very little surface tension. Binders are designed to make the material stick together. Dry Fog agglomerates like size droplets to dust particles and the electrical charges present.
Dry Fog is designed as a stand-alone dust suppression system and typically replaces the bag-house. Collection can be used upstream or downstream of the fog application point as long as it is far enough away to prevent the fog from being sucked into the collector.
