    half-load test run: the filling rate of the medium in the ball mill cylinder is about 20-30%, and appropriate materials and water are given for a continuous test run of 8-10 hours. full load test: after the half-load test and everything is normal, add enough medium inside the ball mill cylinder (gradually increase the ore amount) and run at full load for 10~20 hours.



    this tests results are used for scientific reasoning of conducting more extensive tests on the use of certain grinding media in industrial conditions. – semi-industrial tests are done in ball mills, whose size is closest to size of mills that used in a particular industry (the terms of using grinding balls are closest to operating conditions).
