Alan G., Mine Exploration Engineer, with Olesi 4 Sample Crusher in N. Idaho. I was looking for a small crusher to test garnet rock from www.garnetbrohters.info property in SW Montana. I tried several 4x6 jaw crushers, but found with a slight adjustment to make a larger product, the Olesi 4 is perfect for his testing work. It is lighter than the other jaws. I can easily transport it by hand to the field. It runs on either 12volt for field work or 120 volt for work at home. It out produces other jaws I've tried because the orbital function allows it to crush on both sides, instead of just one side on each stroke. With positive test results, I will submit a bid to Garnet Brothers to upgrade to the Olesi 8 or 12 and start commercially producing garnet products for them. Thank you Jason!
