Nice, this looks like a fun project. Good luck with her!

Love it! Almost a shame to get it dirty. Almost.

Finally tired of using the one man stamp mill. Continually slamming a 20lb ramrod down against hard rock in a cylinder by hand sure gets old quick. So I drew up a prototype for a small gasoline engine powered mill and started work. <img src="http://www.treasurenet.com/forums/attachment.php?attachmentid=937120"/> The 4" feed 14" diameter drum will be powered by the 7hp 212CC Predator as shown from Harbor freight ($89 on sale) Will be using belt drive not love joy. Impact chains are 3/8" #70. Plan to crush to -200 Run between 1,500 - 2,000 rpm <img src="http://www.treasurenet.com/forums/attachment.php?attachmentid=938767"/> <img src="http://www.treasurenet.com/forums/attachment.php?attachmentid=938769"/> <img src="http://www.treasurenet.com/forums/attachment.php?attachmentid=938772"/> Finished product <img src="http://www.treasurenet.com/forums/attachment.php?attachmentid=938770"/> not for sale Go for the gold GG~

you drew this up and did you fabricate and weld it ?

I did everything except the welding and rolling of the drum. The tig welding was done by my nephew, Brian
Took the steel over to a local fabricator to get it rolled for the drum.

that's really cool . I haven't got to see the in side of on until now . And I thank you for the . I have several hundred pound as of rocks to brake down I have collected from the gold mines I have gotten to work at .
I just might have to build one .

 

[roadrunner]

That is a very nice unit and an excellent build.
I can build one now.

I like it and might see how much I got hanging around and how much I would have to buy . Better then my 30 lb pin with a very large bolt welded on it for crushing rocks .

your from Arizona . I go to the GPAA and GSSN claims By Greg's hideout and by mead view . Do you know of other spots that produce I maybe able to check out ?
Went to the GPAA lucky Linda claim by rich hill a couple years ago for a week and found nothing there .

GG, what would you say the drum cost you? Just the 4" & rolling, not the flats.

I'm kicking around the 12" pipe I saw at the steel store, though I could get 4 or 5 four inchers outta that and would have to let a few go. Otherwise I picked up a water tank of about the same diameter I could get at least 3 outta and would completely line with replaceable wear plates.

 

[Goodyguy]

I bought the 4" x 44" x 1/4" steel for the drum from the fabricator and paid $20 for the steel and the rolling. Was a friend of my brother.
The other steel I bought from my Nephew for a dollar a lb and he cut the rounds with his plasma cutter.

All totalled I'd say I have about $300.00 in it including the motor.

Cool. I could roll 3", I think 4 is too wide. I'll have to get the weights of the pipe. Shortest one was ~16".

I was looking at overlapping CRS plates for wear plates because the edge would be the strike face and you could reverse it. Then started thinking of hardened nuts or bolts which could be easily replaced.

I have accesses to cutting edges off blades from cat equipment good hard material. I'll see how much I can get and see if it can be drilled and tapped for bolt holes . If it works let me know what size you would need and a bolt pattern .

Good work Excellent idea on the use of a couple clevis's for hammers. Good source of replacement parts also, but so would chain as that would be easier found out in the boonies. What one does a better job? The short chain or the clevis?

Sure like to borrow Brian to sit with us in our booth at the Elko Mine Show. He sure looks like he could talk mining. Good place to hustle Fab work also at that show. They break equipment out that way by the minute.

Chain is easy to come by, plus when the end link wears you just reverse the chain, that way you get two hammers for each piece of chain.
Also I have two extra sets of chain for replacement which gives me 6 replacements total before I have to buy more chain.

That sound good. Chain would sure be cost effective. A fella who builds this mill setup with the shaker table invited me to have a look at his machine. You can feed maybe 400 lbs. 4" +/- rock a day through in to the small jaw crusher. He was thinking I should add it to the list of things we sell. It was a sweet setup, but at $30K I not thinking I'd find an operation that would go in at that price. They'd either be to small to invest that amount or the mine is a bigger operation and a mill that size just won't cut it as their looking to run 400 tons a day. He said I need to look at the mine test run market when a small run of ore is mined and milled on site to get an idea of the value, as it would be mobile. That be good I guess. I've never went after the mine exploration market all that much other then rock drill bits.

Been in meetings most this week. Lots of thinking time. Mind wondered onto this



Look familiar?

The little balls on the end. What if you took some grade 8 bolts, 2 washers and a nut and added those to the chains end? Just like the balls on the crab.

 

[Goodyguy]

My brother suggested welding large ball bearings into the end links, says they are harder than Japanese math on viagra.

I was figuring the nutsnbolds would be replaceable and the extra edges/faces provide more hammer area. Maybe I'm overthinking it sitting in boring meetings.

Stopped at the steel store and weighed the 12" pipe. Overall 12-3/4" diameter and enough for 4 or 5 sections. With them using a bandsaw instead of me and a cutoff wheel, @ $0.65/lb, each section would be $12.
