Hi Shawn, unfortunately, I can't post a pic here for you, can you PM me your email and I'll send it? send to goldpnr @ yahoo com
It's powered by a 1/2 inch drill, cost me $250 new for complete unit, but you can operate manually if you remove the drill and put the hand crank back on it. I've done that, but you've gotta have the rock samples under 1/4 inch or it's almost impossible to crank. at least for me, that is. I've probably run 200 pounds of rock thru it, and it can crush to what ever size you want. I've found it easier to grind in stages.... coarse down to smaller each time. But then, I like my gold in the samples left unpowdered, if you know what I mean. Not meant for production, just for sampling. It's done well for me, but I no longer can do that stuff. I like to grind all my black sands that are left over after panning to remove the manganese or other coatings and to get the most gold I can from them. Just gotta be patient and enjoy running several stages to get good results.
