The right sized droplets will effectively bind to the dust and supress it. When the droplets are of equivalent size, there’s no getting around it; they collide, combine and fall to the ground assisted by gravity.
A concentrated additive (such as Hydrowet) may be used to improve the wetting ability of the water. However, in cases where fog cannons are required for dealing with visible dust, an additive is not normally needed. Additives are mainly used when supressing respirable sized dust.
Through the principle of fan air delivery, the water is pressurized by a high-pressure pump, and the water is atomized by the micronization nozzle of the pipeline. The water mist is sprayed to a long distance through the air volume and pressure of the fan. Due to the small surface tension of the suspended dust particles in the air If it is zero, the water mist can quickly absorb the dust particles in the air, and the dust floating in the air will be adsorbed when it comes into contact, increasing the specific gravity of the dust, inhibiting the flow of dust in the air, and accelerating the dust settling, thereby controlling the amount of dust.
