Small scale, product grinder

[ports394]

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.

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?

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?

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

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

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.
