Coal dust Wikipedia

网页Coal dust is a fine-powdered form of coal which is created by the crushing, grinding, or pulverization of coal rock. Because of the brittle nature of coal, coal dust can be created by mining, transporting, or mechanically handling it.. Grinding or pulverizing coal to a dust form before combusting it improves the speed and efficiency of burning, which makes the coal
