Dust Extinction Moisture (DEM) is the moisture level at which a material stops generating significant dust during handling, storage, or reclaim operations.
Stockpiles are continuously changing as material is added, stored, or reclaimed. However, some areas of the stockpile may remain undisturbed long enough for the material surface to dry and fall below its required DEM level. As the material becomes drier, it can begin generating wind-blown dust and airborne dust emissions.
TRC Yard Spray Systems are designed to apply water strategically around stockpiles, storage yards, and open material areas. These systems help maintain surface moisture, reduce dust generation, and prevent dust emissions while the material is stored.
Yard Spray Systems are commonly used in mining, mineral processing, coal handling, ports, power generation, stockyards, and bulk material handling operations. They support reliable stockpile dust control by helping maintain material moisture, reduce wind erosion, and improve environmental performance.
