Airborne Dust Liberation During Coal Crushing - CDC

Airborne dust generation is one of the byproducts of coal mining, processing, and handling. The amount of airborne total dust (ATD, respirable size and larger) and airborne respirable dust (ARD) generated is of primary interest for designing the level of engineering controls needed for adequate dust abatement.

Airborne coal dust is also explosive, given the right particle size, concentration, and ignition source. Bureau of Mines studies have shown that ignitable airborne coal dust concentrations start on the order of 50g/m3 (0.05 oz./ft3) [5,6]. The most explosive coal dust size in air is below 75 nm (—200 mesh) [5,6]. Airborne coal dust

Coal dust - Wikipedia

Coal dust is a fine powdered form of coal, which is created by the crushing, grinding, or pulverizing of coal. Because of the brittle nature of coal, coal dust can be created during mining, transportation, or by mechanically handling coal. It is a form of fugitive dust. Grinding coal to dust before combusting it improves the speed and efficiency of burning and makes the coal easier to handle. However, coal dust is hazardousto workers if it is suspended in air outside the co

Airborne Dust Liberation During Coal Crushing - CDC

Through a second series of experiments, the effect of coal rank properties on product size and airborne dust generation was studied using a uniform crushing process with secondary breakage. Laboratory results indicate that secondary breakage of a particular coal notably increases the specific amount of ATD generated, while negligibly impacting the specific amounts of ARD generated.

Airborne Dust Liberation During Coal Crushing

Prior research studies on the relationship between coal rank and dust generation have shown differences between the amount of dust particles created in the product and the amount of dust that gets airborne. Many of these studies focused on studying the amount of fine dust particles created in the product from coal crushing and

Dust Generation - an overview ScienceDirect Topics

In coal-handling plants and raw coal sections of coal preparation plants, dust poses a serious problem. The main sources of dust generation are crushers, screens, dedusters and transfer points between handling units. Other sources are storage piles and railway wagons used for loading or transfer.
