Dust emissions in the industries that rely on bulk materials handling are very common, from mines and port terminals to processing and production plants and factories. They can affect production efficiency, cause material waste and threaten human health. Water spraying is one of the oldest and most popular methods for suppressing dust emissions and is still widely used today in many bulk material handling scenarios, such as crushing, transferring, dumping, and so on. However, reports from industry show that a large proportion of spraying systems do not work very well, and the most typical problem is that the actual dust suppression efficiency of the spraying system does not reach the design or desired value. To improve the design and performance of spraying dust suppression systems, researchers from the Bulk Materials Handling team at the University of Wollongong have applied modern technologies to investigate the characteristics of spraying nozzles and dust particles and also visualis
