This is also never a desired situation because of fire hazard. In fact, to combat this fire hazard, arrangements for millinerting systems with inert gases (, N 2 and CO 2) need to be made (another purpose is to reduce air supply). This is more important for ballandtube mills, especially when these are operated with one side only.

Inerting times vary from 3 minutes to 15 minutes. Most report automatic inerting on mill trip, and manual on mill startup. There is limited information on the damage from mill puffs, however more than 60% of the units report a history of mill puffs. Most of the systems were designed inhouse or are of unknown origin.
