Ebay Chinese Jaw Crusher in Hard Rock Mining Posted January 26, 2015 · Report reply Good point. Part of what I was emphasizing is that today, there are a remarkable number of small impact mills available on the market - made in the USA. I don't believe many of these were available 10 years ago. These small mills can get the little guy into processing hard rock ore quite inexpensively. Processing on the ultra, small-scale may only yield enough to just cover equipment and gas, but that's sometimes all placer mining covers. What I find interesting is there is not a corresponding number of U.S. made mini jaw crushers to accompany these impact mills. It seems like there is a gap that needs to be filled. I would also like to see a more affordable wave table offered. From what I can gather, the wave table is perfect for small batch processing - more so than the shaker table, which prefers a steady flow and larger volume of material to work properly.
