Dust explosion: Is suppression the solution in grain hammer mills?

摘要

There have been newsworthy examples of grain mill fires around Europe in recent years: 2010 Verdelot in France saw the destruction of Moulins Bourgeois mill; in 2014 a major fire broke out in Chancelot Mill in Edinburgh. Recently in 2015 a fire consumed Allied Mills at Tilbury Docks, London. The originating causes of grain mill fires may be varied; a spark, a carelessly discarded match, electrical fault, or grinding and milling friction. However, the fuelling and propagation of a possibly fatal explosion is almost always caused by grain dust.
