The risk of explosions is more or less reduced to an explosion inside the mill, which therefore needs to be explosion, pressure, and shock-resistant. NFPA requires coal mills to be good for 50 PSI. What Are Common Mistakes Seen In These Industries? Constructional explosion protection is the last-ditch defence against explosion hazards.
