Midway Mining & Aggregate
Decided to finally start a new topic geared towards crushing and screening. Seems every time we have shows with dirt we need BETTER dirt without big rocks and clumps. So... I have been searching for some time, smaller laboratory crushing equipment rather than scratch building a new crusher. Eventually I'll get to the screening and conveying part as time permits.
Recently I came across these two crushers on Ebay that came from a gold mine in Colorado. They looked like what I wanted so I had them sent 1400miles to my shop. http://imageshack.com/a/img922/5977/6GmbgK.jpg https://imageshack.com/i/pnmVPO1oj Here is a shot of the jaw crusher. It is a Morse Bros. model 2000 4''x6'' opening. This seems a bit out of scale for what we are doing. I was hoping it was the model 1000 that is a little smaller. https://imageshack.com/i/pl6mHh2uj Second is a 4'' x 4'' single roll crusher built by Joy Manufacturing. Anybody that has any info on the roller crusher please let me know. I have searched the internet without any success for info on this one. http://imageshack.com/a/img924/2383/RCX2Rf.jpg https://imageshack.com/i/plSKdDj5j Here is another one I bought locally off Craigslist near me. Manufactured by, Denver Fire Clay It has the correct size jaws but overall too big. http://imageshack.com/a/img924/8427/pf8Q3s.jpg |
Re: Midway Mining & Aggregate
I've been looking for one to. If you go on EBay, I found a smaller hand driven one that I think a motor could be adapted to, not sure if it's still on there but, it was brand new so I think the guy is making them and selling them on eBay.

Re: Midway Mining & Aggregate
I got around to dismantling the roll crusher and discovered why the previous owner said it was very noisy..... wonder why?

I looked around some to see if I could buy a self lubricating bushing off the shelf. No luck, custom made, so I'll be making some new ones and I'm going to try to insert new graphite plugs in. I was thinking of building the thrust bushing up with some JB Weld with graphite mixed in. Not sure if that will work for a bearing surface though. |

Re: Midway Mining & Aggregate
Added another piece to the company assets. Thought one of these little crushers would be nice for a second stage to reduce the material from the big jaw crusher. Gonna have to add some flywheels to it though

Re: Midway Mining & Aggregate
IDK anything about the second one, but I do know that the Morse crusher is a fantastic unit! In addition to this hobby I small scale prospect for gold with my 3inch suction dredge. Nothing much, NEVER get rich at it. I've found about half an ounce in the last 4 years of doing it. Wa state in my immediate surrounding area(s) is't know for have large flakes, or having a deposit in large quantities of that illusive yellow stuff.
