The problem in a very busy commercial environment isn't burr heating from
bean grinding per se, it's heat from the motor rising to the burrs and
grinds. Some grinders even have cooling fans for the motor for just this
reason.

The conclusion seemed to be that the grounds may gain 10 degrees F in
grinding a typical shot, so it should not be an issue for home use.  There
was disagreement, as you might expect.
