oldguy Posted March 20, 2012 Share Posted March 20, 2012 Don’t shoot me for telling you this. But for optimal milling purposes. The diameter of the jar & the interior jar length should be the same.Or, at least, very near the same. If so, the grinding media in the jar will cascade evenly. Don’t get me wrong, yours will function, but not in an optimal fashion. Link to comment Share on other sites More sharing options...

dan999ification Posted March 21, 2012 Share Posted March 21, 2012 seconded, longer jars suit long cylindrical media or rods, my long jar with rods is as efficient as the shorter jar with balls but not the other way round, the weight of the rods makes up for the low height from which they fall, the lighter balls fall from a greater height and have greater energy in larger id jars. dan.

Mumbles Posted March 21, 2012 Share Posted March 21, 2012 Dan, rod mills are not good at the kind of milling we do. They are meant to crush materials such as rock and what not down to gravel and smaller pieces. By virtue of the design they do this more efficiently. At the same time they also resist producing fine powders. Link to comment Share on other sites More sharing options...
