Re: Stirling piston for a shaker table?

justinhcase, you'll have to take a trip up to Wales, some say there is a bit of a gold rush. Ian S C Welsh Gold is worth about twice the value of gold from else where if you can prove the provenance. Unfortunately the Romans did a very good job of Hydraulic mining , They managed to get at most of t...

Re: Stirling piston for a shaker table?

That is odd.I have been stopped for editing my post's. This is the simplest method that tends to be productive. https://www.youtube.com/watch?v=rLZ4dYErsko Note that the deck only moves about 1" if that. I use Linear bearing so the friction is very much reduced and with the right counter spring half...

Re: Stirling piston for a shaker table?

yes the normal way is to use a crank and shaft with a cam arrangement. No. The normal way is to attach an engine/motor to the table and mount an off center axis weight. When the motor turns, the whole table shakes. That would just make a shaker deck,It would not have the kinetic transfer of energy ...

Re: Stirling piston for a shaker table?

Thank you for taking the time to answer. I had seen similarity's in frequency and reciprocal motion that the two devices share. But if you are of the opinion that it has too low a power density to be of use I will have to take your opinion as text book. I thought it would be a nice idea and of great...

Re: Stirling piston for a shaker table?

yes the normal way is to use a crank and shaft with a cam arrangement. The draw back with this is that when you want to change the nature of the interaction of cam and table you have to make a came with the profile that you hope will elicit the right reciprocal motion. That is fine if you are proces...

Re: Stirling piston for a shaker table?

Well technically it is to separate uniform particles based on density. Not having any gold laden ore as you have in the states my interest is in running electronic material,there is a notable amount of Au and P.G.M.'s in the concentrate. I tend to build all my own equipment as it is cheaper than imp...

Stirling piston for a shaker table?

Hi ,I hope you do not mind me leaking over from an other forum. I normally hang out on the G.R.F. page but have been looking at alternative ways to produce a reciprocating action for a project I am working on. Are you familiar with what is called a "Shaker Table"? It is a method of gravity separatio...

Re: "Hi...We are new here!" First posts here (or anywhere is OK)

Hi.
I am Justin ,I live in Devon England and have a love of all systems and artisan methods of production.
Most of my free time is spent making new equipment as I find off the shelf kit a waste of time.
