Copper Recovery from Electric Motors Using a Turn-Key Scrap Processor

Copper Recovery from Electric Motors Using a Turn-Key Scrap Processor


Hey Guys. My name is Jason with Mt. Baker Mining and
Metals and today we are going to be running this sample of stuff that came from Mexico,
these are little tiny motors off of something and inside there’s this little armature. The armature has copper and steel in it and
we need to break this open and get the armature out in one piece so we can then reprocess
further through the Hammer Mill for the copper to separate the steel so we are going to run
these units whole through this 24″ x 16″ HD Hammer Mill, there’s no screen in it, we just
want to break these apart and get these in one piece, we will hand sort these out and
then we will put the screen back in at about a half inch slot so we can liberate the copper
and the steel out of these. So we will run this thing and see what it
looks like. So here’s the results of our test with no
screen and this is the magnetic fraction, we hand sorted out the material that still
has copper in it, so all of these we are going to have to reprocess. This is all of the material that came out
under the crossbelt magnet but doesn’t have any copper. So now we’ve changed our screen into a half
inch by about a three and a half inch slot. We are going to run these guys, which are
the ones that the customer hand-picked or hand disassembled so we can liberate all of
the copper and steel out of these ones. Then we are going to run, this is the stuff
we got from when we ran no screen, this is where all the copper and steel is, so we are
going to run those. And then just for being thorough, I saved
out three or four whole motors that we are going to run through a half inch slot as well. So we will run this one first, this one second,
and this one third and we’ll see what the results are. So here’s the result from our armatures with
the half inch screen. That they’ve already been removed from all
the plastic and everything else and it separated really pretty good. We have the copper fraction or the non-magnetic
fraction here and then we have the steel fraction here. Like I say the steel separated pretty good,
there are a few, like this piece right here where it didn’t get fully liberated from the
steel, the copper got kind of wrapped up in there. As you can see looking in the bucket there’s
hardly any steel in there, this is the copper, non-magnetic fraction and every once in a
while there’s a little tiny piece of steel that gets through but as you can see this
is you know pretty much pure copper, 99% plus. I’m real happy with the results this is by
far the cleanest we got and it was because they had already hand separated everything
and removed the armature from the plastic and everything else so we got really good
separation between the steel and the copper and I’m real happy with the results. So here’s the results from our second test
where we ran the motors through the Hammer Mill with no screen and pulled out the copper-bearing
part by hand and then we ran it through the Hammer Mill again with the half inch slot. You can see we got really good separation
from the steel and the magnetic fraction and this is the non-magnetic fraction. This is all of the little brass, little brass
fittings, copper wire plastic and everything else that was non-magnetic so depending on
how clean the customer wants it, maybe there are just trying to separate the steel magnetics
from the non-magnetics this would be another option for them, if they don’t want to hand
dismantle every little armature out of that motor. Here is the results from our third test, where
we ran the whole complete motor with plastic and everything through the Hammer Mill at
half-inch minus and you can see the results here side by side, good separation of the
steel and the magnetics from the non-magnetics and as you can see there’s a huge amount of
plastic compared to the copper. So the other option for these two samples
that have a lot of contamination in with the non-ferrous metals is you could take this
material and run it through a 16″ x 12″ Hammer Mill with a quarter inch punch plate screen
or even a 1.2 millimeter slotted screen and then run it onto our wet Shaker Table and
you can get really clean separation of the copper and the plastic using a water shaker
table. So that’s another option for people who are
looking to separate non-ferrous metals from lighter material like plastic and paper, there’s
no other way to do it other then by density separation. So thanks for watching our video of our 24″
x 16″ HD Hammer Mill and scrap line, hope you guys enjoyed it. If you would like any more information on
any of our products please give us a call or email and we will see you on the next video.
