Cheap way to grind stones without spending several days? (4 replies and 2 comments)

Hello, 

I have around 10 Kgs in total of different stone ores like sulfur and quartz and stibnite that I need to grind to 1.5mm. 

However, I don't want to pay much and don't have so much free time to spend grinding. I tried to search for solutions online, but laboratories wanted a few hundred dollars and the guide I was given would require so much time on my part, and I don't have much time

So I was wondering if experts here can give me advice?

Thank you for your time

With such a small amount, you do not have much choice.  You could put it all into a small sealable container and roll it back and forth awhile, or just hit with a hammer.  You are probably spending way more time thinking about than doing.

I see... This is interesting. I will be trying it. Maybe adding some dense metallic stuff and put in the cylinder to help with the crushing..

I tried with the hammer but was  not practical.

Does this method work on big stones (around 15cm) and on hard stones like quartz?

But wouldn't this be too soft for hard stones? For example I am having trouble pounding the galena & quartz with a hammer. I think this tumbler needs to be metallic and spinning really fast otherwise it will take months to be crushed by the tumbler no?
