you drew this up and did you fabricate and weld it ?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~
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 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 ?
GG, what would you say the drum cost you? Just the 4" & rolling, not the flats.
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 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 .
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.
Good work
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
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.My brother suggested welding large ball bearings into the end links, says they are harder than Japanese math on viagra.
