Get QuoteAug 10, 2020 Ball mills are a special instrument used to break up hard solids into a fine powder. They are similar to rock tumblers in that the instrument is a rotating container filled with heavy balls to grind the substance into powder. Ceramic material, crystalline compounds, and even some metals can be ground up using a ball mill.

Get QuoteThese are common problems and solutions when using ball mill. Problem 1 When the ball mill is running, there is a very frequent hitting sound and the sound is also very large. Solution 1 It should be that some of the lining bolts are not tightly screwed. The solution is that you can judge the ball lining by the sound of the machine, then find the loose bolts and tighten them.

Get QuoteThe problem with ball mills vs a simulation like ETAP is that the mill initially is a torque load that is dependent on rotation angle until the charge start to tumble. ETAP only simulates the torque vs speed as a curve. Best bet would be to use a torque peak right off zero speed and then drop down to a more constant torque type of load curve.
