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

With foam dust control systems, you can typically use 10X less moisture and control dust greater than 95% better than water-only systems. Foam gives you the ability to keep the coal from massive gains in moisture which keeps the BTU value up allowing you to burn more coal rather than evaporate water.
Common Types of Dust Control Systems in Quarries. In this article, I will introduce the most common types of dust control systems in quarries. Water spray dust suppression system (Vibrating screen with water spray) The most effective way to suppress dust is wet dust suppression. The most used is the spray dust suppression system.

· Water spraying used so far is found to be not efficient enough in dust control and it consumes a lot of water. That is why KOMAG decided to work on a new type of spraying system to improve dust control in mine air. The development of a series of new air-and-water spraying devices is the result. 2. CHARACTERISTICS OF AIR-AND-WATER SPRAYING SYSTEMS
DUST SUPPRESSION SYSTEM IN COAL MINES HANDLING PLANTS Water spray applications are one of the principal means of controlling airborne dust in coal mines. Since many coals are hydrophobic and not easily wetted by water, wetting agents can be added to the spray water in an effort to improve coal wetting and assist with dust capture.
Dust Suppression System . We like to introduce our new innovative product for dust suppression, based on a system of water/air spraying: The mobile dust system which water and dust particles collide to form agglomerates by the addition of micron size water droplets to dust and dust becomes too heavy to remain airborne and they settle. Our method achieves suppression greater than 90% efficiency ...
