  • What Are the Requirements for Ball Mill Testing, Start and

    Halfload test run: the filling rate of the medium in the ball mill cylinder is about 2030%, and appropriate materials and water are given for a continuous test run of 810 hours Full load test: after the halfload test and everything is normal, add enough medium inside the ball mill cylinder (gradually increase the ore amount) and run atThe testing steps are arranged so that the first step for the testing method is a semiautogenous test, which is followed by a ball mill test Due to the fact the test is carried out in two steps, one can make accurate estimation for capacity and energy requirement for the two products in respective process steps, thus optimize the energyTesting method for ball mills Outokumpu Technology Oyj

  • Technical Note Why is the Bond Ball Mill Grindability Test

    The Bond Ball Mill Grindability Test is a lockedcycle laboratory grinding test It provides the Bond Ball Mill Work Index which expresses the resistance of a material to ball milling This Index is widely used in the mineral industry for comparing the resistance of different materials to ball milling, for estimating the energyThe Bond Ball Mill Work Index (BBWi) test is carried out in a standardised ball mill with a predefined media and ore charge The Work Index calculated from the testing can be used in the design and analysis of ball mill circuits The test requires a minimum of 10kg of sample that has been stagecrushed to 100% passing size of <335 mmBond Work Index Tests Grinding Solutions Ltd
