Dust explosions occur whenever a cloud of fine and dry combustible material (dust) is ignited. How easily a dust explosion can be created depends on the kind of material, but also on the particle size and the moisture content of the dust. The finer and drier a dust is, the easier it is to create a dust cloud; the easier it is to ignite that cloud, the more violent the ensuing explosion is. READ FULL ARTICLE.
