    (10)Press start on the Ball mill. The ball miller should run for the set time of 13 minutes. (11)Now you are ready for a long run. Set in twice the time you needed for the specific sample. Suppose one needs to run the sample for 5 hours. In that case, timer should be set for 10 hours. It is because every 30 minutes, the ball miller will be in off condition for cooling down for another 30 ...
