FRITSCH PULVERISETTE 7 premium line - Manual (Page 49)

If prolonged blow-off noises and the discharge of source material sus-
pension indicate a high internal pressure after cooling, take special care
when you continue to grind. The pressure must always be released after
the cooling pauses (at least for 30 minutes in order that the suspension
can settle) to prevent it from getting too high. Sooner or later, the
increase in pressure will stop.
