Dust Control
The movement involved in transporting gravel, coal, or sand often creates dust clouds. Also, during breaking and demolition work, a lot of dust can be released. The dust clouds can be suppressed by spraying them with water - as a fine mist - for optimal dust control. Adding finely atomized water to the mineral at overflow points and hoppers can prevent the formation and spread of excess dust.
Dust Control with Water Atomization
The movement involved in transporting gravel, coal, or sand creates dust clouds. Additionally, a lot of dust is released during breaking and demolition work. For optimal dust control, these dust clouds can be suppressed by spraying them with water – as a fine mist. The use of finely atomized water at overflow points and hoppers prevents the formation and spread of excess dust.
A dust cloud can be significantly reduced or even completely prevented by binding the dust with a small amount of atomized water. The key lies in choosing the right droplet size: droplets should be 1 to 10 times larger than the dust. Droplets that are too small cannot bind the dust, whereas droplets that are too large form an air barrier that hinders contact with the dust.
Dust Control on Conveyors
Dust control on conveyors is often used in the mining and quarrying industry, or anywhere dust-sensitive materials are moved, such as during coal transfer, although the addition of water in that case is often limited. The movement involved in transporting gravel, coal, or sand causes dust to be lifted and a dust cloud to form, which can be suppressed by dust control with water in the form of fine mist or fog.
Adding finely sprayed water to minerals or aggregates on conveyors or at transfer points and hoppers is an effective method of dust control and can prevent dust formation, suppress created dust clouds, and prevent them from spreading further. The sprayed water can combat the formation of a dust cloud by binding the dust to the mineral being processed or agglomerating it with the dust particles in the air. Dust control on conveyors and transfer points also plays a crucial role in preventing dust explosions and is an important safety system for ensuring safety in processing plants and power generation facilities.
To make preventative dust control effective, coverage and distribution are essential. By ensuring that the material being transferred is fully covered, all material is well moistened, and dust formation is prevented. However, overspraying can waste resources and accumulate on other parts of the transfer equipment. In many applications, surfactants or foaming chemicals are added to help the sprayed water effectively cover and penetrate the material being transported on a conveyor.
Dust Control Using EmiControls
Dust control with water atomization is a highly effective method to limit unwanted dust emissions. This technique is especially valuable in industries where strict limits on dust emissions apply and compliance is essential. By binding dust with atomized water, its spread is minimized. Additionally, it contributes to better working conditions for employees, as it significantly reduces the dust in the air, promoting health and safety. Moreover, water atomization helps extend the lifespan of machines by preventing dust accumulation and damage to the equipment.
