Dust control

How does dust control with water mist work?

The most important factor for effective dust control is the water mist. Its function is to wet the airborne dust particles, which become heavier and fall to the ground. At the same time, the water mist moistens surfaces (material as well as the ground), which prevents dust particles from becoming airborne. The amount of water mist is adjusted to avoid water accumulation on the ground or make the material too wet.

Right droplet size

It is important that the droplets in the water mist are the right size. If the droplet is too large and moves too fast in relation to the dust particle, the dust will not be bound. A smaller droplet moves more slowly and binds the dust much more effectively. Conventional irrigation systems usually create large, heavy droplets, which means that the dust is not bound effectively.

Different types of dust require different sizes of water mist droplets to achieve optimal results. EmiControls' advanced valve technology allows the machines to create water droplets in the range of 10 to 100 µm (ideal for dust control) and the equipment can be configured according to type of dust and operating conditions.

Optimal water mist amount and distribution

Is the dust mostly airborne? Should the material in the process or on the ground be soaked preventively to avoid the dust becoming airborne at a later stage? The right amount of water and distribution of the water mist is important to achieve a good result and effective dust control.

The amount of dust in the air is measured in mg/m³. Together with our supplier EmiControls, we have extensive knowledge and experience in determining the amount of water per cubic metre needed to acheive effective control dust in different environments.
