DIY rock crusher

hi all
looking for some ideas to make a cheap rock crusher
I have searched the forum but not come up with much
I recently dropped on a small area with a lot of very rough prickly reef gold
I have crushed some sample rocks in a dolly pot and recovered some fine gold using a gold pan after crushing
just looking for a way to speed up the crushing process
any ideas would be appreciated

regards

There was an  engine driven one  that sat on top of a 20 lt. bucket  Somebody else might come up with more details .

Think it was like a hammer mill .

Hi mickb

I was going to make one years ago but never got around to it here's a link that may be useful.

I have seen these, don't remember where you get them in Australia.

I think   there   was a guy in W.A .   that was making them ....

Was Keene making them at one time ?

like the idea of the one that attaches to an angle grinder
would be perfect only looking to crush small amounts
might be able to fabricate / cobble something together lol
thanks for the reply's

You can buy a Keene rock crusher that sits on a bucket from Reeds prospecting supplies in W.A. Cost is AUD$1,490 . Reeds made one but looks like they do not make it any more .
