Coal drying & Grinding. Coal Mill | by A.Sen | Medium

Therefore, a target of % surface moisture (S.M.) in ground coal (we may call it as fine-coal) is necessary to fix while grinding. The recommended residual moisture (S.M.) content depends on content of hygroscopic moisture (I.M.) in the raw coal. And target moisture in ground coal is suggested to maintain 1–2% more than inherent moisture.Pulverized Coal Explosions in the U.S. Utility Industry,Coal Volatility: Explosion frequency increases with an increase in volatility content, but this trend is as weak statistically as the others. These statements and the appearance of Figure 2 remain unchanged even if a dry, ash free basis is used for volatility. Coal Moisture: Explosion frequency remains unchanged with increasing coal moisture.[PDF] 1 COAL DUST EXPLOSION HAZARDS by | Semantic Scholar,Although coal can be handled safely and can be an efficient fuel, there are explosion hazards which are accentuated as the particle size is reduced. Particle sizes of coal which can fuel a propagating explosion occur within thermal dryers, cyclones, baghouses, pulverized-fuel systems, grinding mills, and other process or conveyance equipment.
