giod Posted August 30, 2013 Posted August 30, 2013 Got some titanium sponge can it be ball milled to a finer mesh in a ball mill with lead balls, or is the Ti to hard to be ground by the soft lead? and yes I am aware some aren't in favor of milling Ti. Thanks!
mabuse00 Posted August 30, 2013 Posted August 30, 2013 (edited) It will definitely ruin your lead balls in short time and I don't think your Ti will even be reduced.Forget it. Get some fine stuff and save the large Ti for salutes. Edited August 30, 2013 by mabuse00 1
jeffreyschultz Posted August 31, 2013 Posted August 31, 2013 Is there a media that would work in place of the hardened lead for milling Ti?
nater Posted August 31, 2013 Posted August 31, 2013 Milling metals is dangerous as it is. You need a special mill jar and be caref that the finely milled metal could become pyrophoric when you open the jar and expose it to more oxygen.
schroedinger Posted August 31, 2013 Posted August 31, 2013 Yep, diamonds should be fine. Steel would work, but the waer rates would be so high, that you would get a lot of steel inside your Ti, which won`t be milled a lot, best way will be to use the search for this topic, as there is a god thread about this, using a coffe mill type blender (700 watts) and milling under water
TheExplosionist Posted September 7, 2013 Posted September 7, 2013 Tungsten or steel is best for grinding metal. Last time I checked 1" tungsten carbide media were £10 each so not cheap.
dan999ification Posted September 7, 2013 Posted September 7, 2013 (edited) What mesh is it? What do you want to use it for? How much do you need reduced? I like the coarse stuff but have reduced some ti sponge in a pestle and mortar ( and some 10 mesh feti) only an ounce of each but it is possible, if you need more forget it. Where are you? I have some 0-100 mesh the majority is finer than 300mesh I have no use for yet except maybe tails if it doesn't burn up In the stars. Dan. Edit: the blender thread is reducing brittle mgal sponge will wear the blades. Edited September 7, 2013 by dan999ification
Areonic Posted September 7, 2013 Posted September 7, 2013 I was just always taught to never ball mill any metals. Guess I must be the only one,lol
jeffreyschultz Posted September 10, 2013 Posted September 10, 2013 @areonic1, you aren't the only one. I do not plan on attempting this, even though I probably have 100 lbs of spherical titanium metal and titanium hydride of varying mesh sizes. In a previous thread, I did mention that I have a glove-box like container I built a while back for some chemistry experiments that does have ports for purging the environment and replacing it with an inert gas, but this is something that is beyond my immediate interest and comfort level. I was purely interested in what sort of media was general used for this purpose, and I don't have any plans of making such an attempt. From the sound of it, it seems that it wouldn't be economically feasible at the hobbyist level.
