Spray Water Dust Suppression For Coal Crushers
Dry Fog Dust Suppression Conventional Methods
Traditional water spray dust suppression systems are the least expensive, but present problems which make them impractical for most crushing and screening plants. Water is used to dampen the surface area of the product to prevent dust from becoming airborne. Chemical wetting agents may be added to increase the surface covering capability, and large
Coal seam water infusion for dust control: a technical ...
· Coal mine dust continues to be a health and safety issue in underground coal mines. Coal seam water infusion was developed and widely applied in European coal mines for dust control, and was also a common practice in most Chinese coal mines. This method typically involves the infusion of water into the coal seam to increase its moisture content, and therefore reduce dust generation .

However, sprayed water has a large surface tension and coal dust is extremely hydrophobic, which limits the efficiency of dust suppression sprays in coal mines (Wang et al. 2020a; Xu et al. 2018; Han et al. 2020b, a). Some studies report the addition of surfactants to water, which provide the resulting solution with a lower surface tension

Enviroflo/Nalco Dust Suppression Systems. In instances where there is a shortage of water or where there is a limit to the amount of moisture that can be added if the product is to be fine screened, for example, where the minimum mesh size is below 4mm, high moisture contents above 1% 2% can cause 'blinding' of the screens that will seriously impair screening efficiency.

Dust Suppression Nozzles
The movement of conveying crushed stone, coal, or sand, stirs up and creates a dust cloud, which can be suppressed by spraying water as a fine mist or fog. Adding finely sprayed water to the minerals or aggregates on conveyors or at transfer points and hoppers can prevent the generation of dust or suppress created dust clouds and keep them from spreading.
