hey guys my name is jason with mount baker mining metals and on today's video we're going to be
cleaning up some of these motor stators and some of this electric motor shred residue we're going
to clean up the copper and increase the value here's a close-up of some of the stuff we're going
to be running and these are the internal guts of electric motors there's some transformers here
some of it's been through a shredder and liberated from the motor and and housing and stuff
some other stuff looks like it's maybe been dismantled i don't think this one's been through
a shredder but but there's a lot of copper in this there's a huge amount of value in here but
it's contaminated with all these steel plates some have shafts on it and stuff and so we're going to
shred this up to a much finer uh shred and break up all these steel plates from the copper wire
through one of our bigger 34 by 24 hammer mills send it through uh the hammer mill with a one inch
slotted screen and then under a mag belt to pull out the steel and all of our our copper wire will
come through clean and uh we'll see what it looks like but we're hoping to get a number two product
number two copper wire product out of this stuff and um almost all the stuff we can run
our limits on the machine that we set are anything under 20 pounds uh that you know a
stator like this these are these actually break up pretty easy because they're just a bunch of plates
glued together but anything under 20 pounds and anything with a shaft you know something like this
anything with a shaft or a solid metal piece in there uh that's less than a half inch so there's
a few pieces in here we probably won't run today like uh like this one here that's got a pretty
good size shaft and that's just a huge essentially solid chunk of metal here's another one with a you
know a pretty hefty shaft so like i said anything under about half inch uh and less than 10 pounds
with the shaft or anything under 20 pounds with uh like a stator transformer and those will go
through uh just fine and some of these bigger ones you know like this piece here is over 20 pounds
but one of our customers actually bought a little shear and you can just sheer this down two or
three pieces to get it under 20 pounds and then run it here's some of the other material this is
uh some of the smaller stuff again this is all most of it has been through a shredder
and uh there's still a lot of value here so we'll get this cleaned up and then on another
section of the video we've got bins and bins of um brand new or not brand new but but cleaned up
stators they haven't been through a shredder i think these were probably dismantled by hand
um but we've got a tote of these as well so we'll get these uh sorted and um and we'll run them and
and hopefully get quite a bit of copper out of these
so
um

so
this

foreign
so
um
right
so
music
foreign
thank you
all right guys so here's the steel fraction from the pre-shred motors so let's take a look
at this stuff and then we'll go take a look at the finished copper product here's all the
motor plates and the transformer plates that went through the one inch screen and you can
see it's it's pretty darn clean all right we got our pre-shred copper in this bin it's about four
feet tall four feet wide and three feet across this way and it's about half full i would say
and so you guys can get an idea there was a little bit of cast aluminum in there like on uh
motor plates and stuff and and end caps and motors so there's a little bit of cast aluminum in there
that if you're being a little bit more picky about it you can make sure those get picked out
here's another piece but i don't know if that little bit of aluminum is a problem and obviously
there's some paper and some fluff and stuff in here but for a number two copper product i think
this is pretty good what do you guys think would this pass in your local yard for number two copper
we ran three thousand pounds of this stuff in uh an hour and ten minutes so you're looking
at twenty five hundred pounds or three thousand pounds an hour most of it was under 10 pounds
10 pound pieces and so they went pretty fast
and we ran it through a one inch screen so again this is the pre-shred motor stuff or the copper
meat balls or whatever you want to call them now we'll go take a look at the motor stator copper
all right guys well here's the results of our stators through the hammer mill and these came
really pretty clean there's still some of that fluff in there
but our customer says that that's not a problem it doesn't weigh enough to
contaminate the copper so he's happy with it and we ran we were running about 2500 pounds an hour
through the one inch screen and these stators we measured them at about 25 to 28 copper and again i
think this is a number two product uh let me know what you guys think with this pass is number two
at your local yard but most of these stators were 15 to 18 pounds again we max out at 20 pounds
and we ran about four hours here uh so we figured we ran about 10 000 pounds
of stator so we have probably about 2 500 pounds of number two copper here it's going pretty well
here's our steel fraction
and we've got uh somewhere around 8 000 pounds of steel here
but you can see it came really nice and clean there's very very little copper in there
i mean even the plates when they rolled up and stuff they didn't they didn't
pinch any copper in there and here's the machine that's a 100 horsepower motor
wired at 480 volts and it draws about 120 amps at max load
and i was feeding that thing we have a little amp meter that i was watching and at idle when
it's just turning the rotor it spins about 45 amps it pulls about 45 amps when it's running
and then when you throw in a stator it'll jump up to 100
or 110 and i was waiting until it got down to about 55 amps before i threw another motor in
um you might be able to push a little harder than that i'm not sure like i say i was kind of being
ginger with it trying it out experimenting a little bit with it but that's how we ended up
getting our 22 2500 pounds an hour of stators and about 3 000 pounds an hour of pre-shred
here's a look inside our 34 by 24 hd hammer mill and we've taken the rotor out uh but you can see
the the screen here is a four inch actually i think this is three and a half inch squares
and this is for like a pre-shredding situation where you're trying to liberate some some large
metal pieces from non-ferrous or just trying to shred large bulky items like printers and and fax
machines and stuff like that we sold several of these machines just as a as a shredder so
there's the four inch screen we'll go take a look at the one inch slotted screen as well
so here's the one inch screen i mentioned earlier and it's a one inch uh slot and it's about three
and a half inches long we have these big huge strong backs that we weld on the back of them
this screen obviously is upside down when it is installed in the hammer mill it flips over
but there's the there's the screen
so here's the rotor we're just getting ready to install it in the
hammer mill i got to put some bearings on and uh and the pulley
but i wanted to give you guys an idea of the hammers that we're using here
i think each one of these weighs about 22 pounds and we do four on one side
and four opposite you can see it there for balance and so on this hammer mill with uh the stuff we're
running today we're only going to be using eight big hammers but at 22 pounds a piece you're gonna
have uh almost 200 pounds of steel flinging around in the inside of this thing and so that's gonna
bash up anything we throw down there so thanks for watching our video hope you guys enjoyed it if you
have any questions or comments you can find our contact information in the description below or
in the lower left corner of the screen so thanks again for watching and we'll see on the next video
