I suspect that a combination of the two systems might be best. The
point of source removal from the mixer is fine for what it does, you
also need air removal for weighing out clay, dust on the floor and
everything else. Make sure the blower is big enough. Down here in S
Texas when someone installs a slot hood it sucks but doesn't suck
enough. Couldn't help myself.

I just wanted to share my latest experience with dust collection. I wrote
a few months ago about looking to cut down on dust while mixing clay. I
teach a full high school ceramics program and all the clay we receive is
in dry form. The ventilation was poor to none, so the school purchased a
bailey hood that bolts to the top of the soldner mixer lid. This hood,
however, does not come with any time of fan/motor to help exhaust the dust
(I'm not sure what they thought the hood would do by itself?!). To make
solving the problem more difficult, my mixing room does not sit next to an
exterior wall (making it impossible to expell the dust outside). My
school then purchased a self-contained JET dust collection unit. We had
to buy an extension hose to add to the one that comes with the Bailey
hood. I must say I'm pretty impressed with how it works so far. The
filters seem easy to change, and the collection bag is quite large. The
exhaust is powerful (even on the small 1 1/2 hp motor), so you have to be
careful when adding the clay through the opening in the hood - clay dust
is so light that it whips right up the tube before falling through the
mesh. I found that if you stand the bag up on end so that the clay stays
contained by the sides of the bag, the clay goes where it is supposed to
and only the residual dust escapes.
I haven't had the unit long enough to see how often the filter needs
changed. The only downfall I see for now is the noise it creates. My
maintenance staff was thoughtful enough to build an insulated wall around
the unit to cut down on the noise (However with this, I lost a large table
and all of my glaze storage space).
I'm unsure where the school got the "dust dog", but I did find the same
unit online - less than $500, plus the cost of the bailey hood, of course.
Just google "Jet Dust Collector 1 1/2 hp"
In conclusion? Bailey should make a dust collection unit to go with that
hood and save us all some running around!
Thanks for letting me share,
Melissa
