Has anyone designed or seen a good dust collection system for Soldner clay
mixers. Our facilities (Miami University in Oxford, Ohio) were renovated
several years ago and the project engineer designed a canopy hood that is
suspended above the clay mixers. We have two Soldner mixers and the canopy,
which is on pulleys can move back and forth between the two. The problem is
that when someone is adding dry clay to the mixer the overhead exhaust
pulls the dust up past the person's face. The university's Environmental
Health and Saftey Office has recommended a slot wall unit that would create
a curtain of air pulling the dusts away from the worker. But the wall unit
would have pull a curtain of air some 40 inches or so because the front
edge of mixer is that far from the wall.
The EHSO would like to see something custom fitted that would wrap around
the mixer but that might inhibit usage. Does anyone have any
recommendations?

Cut a hole in the back of the mixer lid. Attach the hole to a blower
exhausting outside.
If you make the tube on top of the mixer have a large cross section it
will not pull out heavy clay particles only the smaller stuff. It will
keep the mixing tub under negative pressure.
Don't mount the blower on the soldner. It will get beat up, wet etc.
Discuss this option with your safety officer to help with blower sizing.
If you vent the blower first into a large diameter Steel drum and then
vent the drum to the outside you can probably save some of the dust for
reuse in your clay.

Alfred University used a siphon which sucked from a hole in the lid,
enabled the lid to lift up and out of the way. Call Bobby Scherzer at
Alfred U for more info.

Here at Bath Potters'Supplies we have two dust extractors made by a
company called Nederman,based in Preston,Lancs.UK. these feature an
"Elephants Trunk" which you position over the dust creating machine. A
number of colleges here in the U.K have them as well, and these things
have to be good to get past our Health and Safety regs.I don't know if
the company have a USA base but the UK phone No. is (44) 1772 334721
they are very good extractors.

Try extending ductwork as close to the mixer as possible. Put the vent's
collector at the side next to the top lip of the machine. Try to do a half
ring or more around around the lip.
