Dust Generation In Coal Crushing
Fire and Explosion Prevention in Coal Pulverizing Systems
In general, for a given system with coal dust dispersed in air throughout its volume (refer to Figure 1, Time = 0), the ignition source ignites adjacent suspended coal dust. Energy transfer from the burning coal to the next increment of unburned dust is by ordinary heat transfer, and if sufficient, will ignite the unburned 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.
