Small scale, product grinder

Small scale, product grinder

Small scale, product grinder

(OP)
I have a product that is very staticy, and has a very low bulk density.  Basically cotton balls look like gravel compared to my product.
Can anyone think of a lab, table top sized unit that might be good for grinding this?

What I'm thinking is a vacuum blower connected to a cyclone that pulls through the bottom of a hammer mill.  The bags/cyclone can be pulsed with air to drop the product out.  

But I'm not sure if this would work with such a low bulk density, and the static.

RE: Small scale, product grinder

One thought:  Eliminate and control the static with de-ionized air.  Get yourself the static sensor to quantitatively verify the amount of charge on the object.

tygerdawg, I've never tried that.  Not sure I can do that in the lab.  I wonder if just pumping some deionized air into the container where there product is being held, before grinding could reduce static?

RE: Small scale, product grinder

Put it in a home dryer with a dryer sheet.  Tumble a few times or more - see what happens??

Mike,  are those things food safe?

RE: Small scale, product grinder

I never ate one - so not sure??!!

RE: Small scale, product grinder

I am sure you can read the label or get a MSDS sheet on them which should explain any problems!!

RE: Small scale, product grinder

Would it grind in a jet mill?  Use gas to make the pieces hit each other basically.
As for static you could look at humidity control or a small amount of radiation.  Are you old enough to remember the anti-static brushes for you LP's?  They had a small radiation source in them.  It is behind a physical barrier.
