Scale Up Method Of Planetary Ball Mill EDEM Simulation

The objective of this paper is to investigate the scale-up method of the planetary ball mill by the computational simulation based on Discrete Element Method. Firstly, the dry grinding of a gibbsite powder by using four different scales of planetary mill was developed to compare the grinding rate with the specific impact energy of balls calculated from computational simulation.

What is a ball mill? What are its uses and advantages? Quora

Sep 04, 2018 · A ball mill is a grinding device that is used to turn material into fine powder. Ball mills are cylindrical in shape, and are often the grinder of choice when it comes to mashing paints, ores, ceramic materials, and certain hard chemicals. By rotating on a horizontal axis, a ball mill can effectively convert a hard material into a loose powder.

Rod mills, how they function Mine Engineer.Com

Rod mills operate at lower speed than ball mills since the rods are rolled and not cascaded. For an equivalent grind, a rod mill uses less steel than a ball mill because of the lower speed and better contact between the media and ore. The rod charge must be maintained in good working condition, and broken and worn rods must be removed.
