In terms of the dual seal I think just a back up in case one fails.
I have seen two seals used where the seals are packed with grease prior to installation the second seal helps to retain the grease for lubrication.
If the seals run without lubrication they die

That was my thought Dave,
It is meant to act as sort of a packing filled with grease. Bear in mind Ed this is just a guess, I know nothing about your mill.
