Where can I find a centrifuge to spin a kg or more of MeNH2.HCl. I'm not interested in a salad spinner, something more industrial.
Thanks

Check out the web site for Sharples centrifuge. I hope you have a lot of money.

If that's too expensive one could assemble one from various scrapyad parts, if one was crafty enough

How about an old washer ......just modify the inside and it'a a ready made cantrifuge.....and use the spin mode........solo

Or possibly a hand driven cream separator like grampa used out on the farm. But these are antiques and probably also expensive.

My dad has a plastic hand cranked collender, works the same way as a washing machine does. Looks pretty inexpensive.

Old style washing machines had a separate centrifugal water extractor, these particular models would provide the most easily used mechanical parts
The most critical knowledge for such a project was provided in this old post,
unfortunately not available presently:

Electric Motor Explosion Proofing Modification
(Rated as: excellent)
From Ind Eng Chem 675 (1926):
To prevent sparks from the motor igniting volatile solvent fumes, the principle of the Davy lamp was applied. The air holes at the brushes were
covered with 50 mesh copper gauze, welded on. The motor was then run free and under load in explosive mixtures of benzene, gasoline vapor and natural
gas. No explosions occured, although the brushes were sparking badly. Under similar conditions the same unprotected motor invariably detonated the gas
mixtures. It should be noted that this modification gives no protection from the improbable event of a spark between the shaft and bearings, but this
is a rare occurance.
SWIL would test this in a small test chamber before trying it with diethyl ether or hydrogen. SWIL sees no reason brazing couldn't be used to attach
the mesh either.
