Zmuro Posted January 9, 2012 Share Posted January 9, 2012 (edited) Your opinion about these jars? http://www.curtec.com/en/products/conductive-drums/21 Zmuro check the other jars at home page..maybe you will find the jar you are looking for. Are they available in Europe like in online shop , I know Inoxia has them but they are a little pricey. Edited January 9, 2012 by Zmuro Link to comment Share on other sites More sharing options...

JFeve81 Posted January 9, 2012 Share Posted January 9, 2012 Hey Col, Just a quick question on those jars. There is an o-ring in the lid to keep black powder from reaching the threads. Check. But how about when you dump out the black powder after a run? Link to comment Share on other sites More sharing options...
athlon Posted January 14, 2012 Share Posted January 14, 2012 Yep, KISS works on ball mills also... I have been trying to make my ball mill mill with two jars at the same time, but unfortunately the friction was not enough to get a second jar to roll against the idler wheels, so I thought about making wooden pulleys and a belt between (The red in the picture) to get the idler wheels to work also. What I didn't think of was that the idle wheels were of smaller diameter and therefore the pulleys needed to be different sizes. Then I had a cup of coffee and moved the other set of idle wheels (seen on top of the picture) so the jar sitting on them is in contact with the drive wheels... Ball mill is seen from the top in picture. Link to comment Share on other sites More sharing options...
Zmuro Posted February 2, 2012 Share Posted February 2, 2012 I'm having trouble finding those curtec drums in my country, so I decided to build my own ballmill jar. I have 25cm ID pipe and I have already cut end plug and cap from wood. End plug is secured with screws, but I don't know how can I secure the cap. Do you think I could use aluminium rod that would go trough the center of end plug and cap, to secure cap with washer and nut? Link to comment Share on other sites More sharing options...

Col Posted February 2, 2012 Share Posted February 2, 2012 The threads on the jars are pretty huge,.you`d need to plaster bp into the threads with a trowel before you`d get any measurable friction Link to comment Share on other sites More sharing options...

You could screw or bolt a flange fitting to the wood (koi pond bottom drain / tank connector seems ideal) and use a large rubber end cap/ hose clamp on that.something like this one: http://www.absolute-...om/prod288.html Edited February 2, 2012 by Col Link to comment Share on other sites More sharing options...
