If I were to ask a price for a second hand Ball Mill, how much would I be looking at?

I dont need a really big mill, just big enough to do the tasks for personal pyro.

Thanks,
Karl

If it's commercial, you'd probably be getting a rock tumbler, and since they're hardly a popular or comon item, it's a seller's market. Hence, not much less than retail.

It's way more fun to build your own, anyway, and that way you'll get a much more efficient (i.e., faster milling) machine, and with whatever jar capacity you want. Depending of how ingenious you are at scrounging, it can work out a lot cheaper, too...

There's a truly epically large thread on ball-mill design and construction here.

Take a look at this one on Ebay, looks a jem, sadley if the wife was to find out I'd bought it we be heading for a divorce, as I'm banded from Ebay; but still I'm tempted, good luck anyway...

thats one nice looking mill!

would probably need different barrels, personally i'd be a little worried about milling an expolosive in a ceramic barrel?

Wow, that is a nice mill. You know... the ceramic jars would be poor for milling black powder, but I bet they would be ideal for pure chems and metals. If a person could justify a separate mill for that, what a deal.

Yeah nice mill, but what is going on with the delivery price??!!

Anyhow, I heartily recommend the Evans CR2.. it is like the one on eBay above, where you can have multiple barrels milling different things (2 of the large ones or 4 of the small ones, one one large and 2 small) at the same time. The rubber barrels are real nice too.

Thanks for the link Adam. What's it like for safety i.e. wiring, sparks etc. accessible to powder dust please?

[adamw]

There are from what I can recall 2 angled 'vents', so that is the only place where dust can enter, and is unlikely. Inside everything is neat, and there is just the motor connected to the mains cable, so no switches etc to create any sparks.

The Pascall mills are excellent - I have a similar model with moveable rollers, and a speed adjustment. The ceramic jars are perfect for milling single chems, but I wouldn't want to mill BP in them - I think the thick-walled porcelain would make some horribly nasty shrapnel if the worst was to happen.

At ?26, that mill is extremely cheap, and Pascall are no longer in business, so I would snap it up if I didn't already have one... The jars alone cost a ridiculous amount!

Which barrels are best for Machester minerals ball mills? rubber? or plastic? are they rubber on the inside or just the outside? anyone got one?

Also on some of the other mills such as the beach 2.25k the barrels are for stone or metal, would this make any difference for milling BP?

[cooperman435]

Does anyone have any opinions on this rock tumbler or does anyone use this model already?

It has a rubber liner but a steel barrel!


Im liking it because of it large jar diameter and hexagonal sides which will make milling small batches very fast and efficient.

Let me know guys

I know people who have used those before with good success. The rubber liner is pretty rugged, so the whole steel thing wont be an issue.
