Stone Dust Requirements

Stone dust tends to fall out earlier than coal dust due to its coarser size and higher density. This causes the incombustible content to rise away from the duster. Almost all of the stone dust distributed by the trickle duster was seen to fallout within 100 to 150m of the source.

The Effectiveness of Rapid Stone Dust Compliance Testing ...

2020-10-13 · Stone dust, which is derived from limestone, gypsum or marble dust, increases the TIC of the roadway dust to the point where it is no longer explosible if subject to a potential ignition source (Jensen and O''Beirne, 1997). The addition of stone dust to the fine coal dust acts as a dilutant, heat sink and oxygen/gas obstruction (DNRM, 2003).
