lead to belt slip. For the coal dust to be removed from the air, the water particles need to be of a similar size. This in turn means a collision between dust particle and water droplet is more likely (Figure 2). Figure 2. The effect of water droplet size on dust suppression. The design of spray head is therefore of paramount importance
The techniques to improve plain water-spray dust suppression include a reduction of droplet size, an increase in droplet frequency, an increase of the droplets velocity, or a decrease in the droplets surface tension, making it easier to merge with dust particles.
Water spray suppression techniques include the application of water, surfactants or foam at the crusher, conveyor feed and at other discharge points. Systems may be pressurized or rely on available water pressure. Wet methods can also control dust exposures downstream
Nozzles can spray a fog of correctly-sized water droplets to remove the dust from the air. This mitigation is critical at conveyor transfer points, dump pits, loading hoppers, extraction points, rock crushers, truck dumping locations, stock piles, and any other place where product is moved or stored.
