I meant to add to my earlier post:
If you can't locate a good place on the pugmill where the clay will
not enter the vacuum inlet tube, there may be another solution.
Imagine a piece of PVC pipe, an inch or inch and a half diameter,
about 6-8 inches long, threaded on both ends. Wrap the threads in
Teflon tape (plumbing supply again or Home Depot).
Put a threaded cap on each end, into which you have drilled and
screwed a fitting to adapt to the line running between the vac pump
and the inlet tube on your mill. Place the gizmo I just described
_vertically(!)_ in line with the tubing, like an inline gasoline
filter. Any clay that gets sucked in to the vac line will stay in
that large PVC pipe, and you can unscrew it for cleaning later.
(The air traveling through that vacuum line will not have a lot of
velocity, so this will work.) Yes, you can stuff a lawnmower air
filter (foam) element into it (in use now on most small push gas
mowers) to further impede the clay, and save your vac pump. Usually
stops water too, but not moisture.
Clay (especially heavily grogged stoneware clay) in the vac pump is
not a good thing. Don't ask me how I found that out.
Best,
