cone crusher speed test results

One of these variables is the eccentric speed at which the cone gyrates. In June 2012, pilot tests were conducted on a 200 hp high speed cone crusher to determine the production and operating conditions over a wide spectrum of eccentric speed

    The data are machine specific, however the trends of the results are relatable to high speed cone crushers of relative size. The results showed a relatively small difference between crusher production when running with a super-choked cavity (material above the crushing chamber 300 mm) as compared to a full cavity (material up to the top of crushing chamber)

    Feb 01, 2011 In conclusion, obtained results indicate that significant gains can be made in terms of both product yield and process capacity by the adjustments of cone crusher operation. For instance, the case study of the 2–16 mm product yield shows the benefits of operating cone crushers at a small eccentric speed, with a large stroke, and a large CSS. It can also be concluded that a crushing process with both single particle and
