Appears to be a solid molded drum made out of rubber?
Let us know what you find out.
had a phone rep whatsapp me and she sent all my questions and requests to an engineer in the company maybe get an answer tonight
i believe just the rubber drum with the continuous spiral riffle was $200 usd, they havent got back to me yet on a rubber bowl with no riffles

list small units for test tubes. Not sure about scaling up in size. Very high speed like 10,000 plus RPM's.
had to replace the valve stems on my dually rims yesterday and couldnt help but to think it sure had a nice bowl shape to it. wouldnt be hard to weld a 40 gallon drum or steel pipe to it and then glue in a rubber riffle. might have a lead on a used neffco bowl
then that got me into thinking of front wheel drive cars with disc brakes and a cv joint
now you have a solid base that can be driven by a belt drive pulley and you could bolt a stainless or any bowl to the lugs and the rotor for support and if you need parts just go to any parts store for whatever fails

Perhaps the rim bowl shape could be drilled to bolt in a rubber shape?

the 'lil bertha gold centrifuge about 5 years ago was a start-up operation .about 2 grand . gas or electric.
i visited a guy who had one to try my raw material. if i'd had any gold i'd have one of my own. thru put as fast as you could load it.

Any pictures or size dimension's of rubber?
Rubber is to be glued in right?
no, you could try and get them to send you a profile pic lol
i was on their site before, i didnt see a neffco bowl anywhere.
they had what looked like a chinese bowl with a belt drive just more refined looking.
i could ask if that is the new neffco bowl but anyone can just go to their website

Well the $1000.00 cost of a 100 ft. is high if the life is not good. Any profile will work for a period of time. Thanks for the follow up.
