  1. For sure! With ore that rich the only pain would be having to fish out the golden pellets from the impact mill
  2. Yes, if you reduce the feed size you will reduce the wear
  3. Your picks look good. I considered discs too. I just made for my own use. My jaw is separate as easier to move and load that way, but is a lot easier to get consistent 1/4 to 1/2 inch feed than a dolly. 32 kg in a dolly must not have been fun. The sugar grains and intermediate grains are what I wanted to avoid, as they are a pain in the final stage. You can reduce them with smaller discharge, but then it slows up the process a lot.
  4. This is my AR600 one. I used to use 400 but wanted more durability
  5. I have also switched to AR600 for building picks and these applications. Endurasteel is also good
  6. The plates dont create a chunkier output. It is the same if not more consistent than when I tried a chain, since that is mostly controlled by discharge plate. The reason for the roller mill is two fold. 1. It allows higher rate of throughput through the system, as you are not constrained by output size in the impact mill as much for fine grades i.e. you can have slightly larger slits in discharge plate yet get finer more consistent output faster. 2. The roller mill allows you to control output size very consistently since it is adjustable, and you can get a much finer grade of output. But it is really consistency, as there is much less variation in the distribution of output size if you are going to table it. These only really matter if you are processing more than a couple of rocks in a test sample
  7. I guess beauty is in the eye of the beholder. I don't pretend to be a welder. My set up is impact mill on top of roller mill so I have consistent size with one pass. I have jaw crusher for breaking down to size for the impact mill. With this I have never had to change chains. Still has metal in crush, but much less as hardfaced. I made it some time ago so also hardfaced near removable disharge plate where it was wearing.
  8. I have plates with hardfacing on the final chain link
  9. Where in Europe is not either one of these?
  10. I could not agree more. There is little like the excitement of a patch no one else has found, and the overall weight more than makes up for the days where the gold wasn't where you thought.
  11. I see this as being particularly useful for problematic hot rocks, especially if you can grab your sample on the spot. Perhaps even as a smart ground balance.
  12. Gold still seems pretty coarse particularly on edges, like it hasnt come that far. But maybe that is just the photo
  13. Have you considered using a post hole auger to test before you dig?
