Hey guys my name is Jason with Mount Baker Mining and Metals and today we're gonna be running a sample of little tiny electric motors
and transformers through our scrap line.
And this behind me is our 24 by 16 HD hammer mill it currently has about a half inch by 4 inch
long slot in it and it's run with a 30 horse three-phase electric motor.
The materials going to discharge down onto this conveyor belt
which is going to carry it all up under to a cross belt magnet. This will pull out the steel fraction anything magnetic
down into here. The non-ferrous and
non-magnetic are going to go up through a zig-zag, this is designed to be hooked up to an air
classification system but today we're not going to run it for the customer
per the customer specification. And then the non-ferrous is going to fall down into the wooden box there.
So let's go take a look at the sample are going to run
So here's the sample we're going, to be running today and these are little tiny transformers little electric motors
As you can see they have
plastic and a little metal and steel in with a bunch of copper which is for this customer the valuable
The valuable material we're going to try and recover
So we'll run this, through our mill and I'll show you guys how it works.
Okay, so here's the sample after you run through the scrap line. And I wanted to contribute the two fractions this is well start with
the copper fraction or the non ferrous fraction and this is everything that went under the magnet
and I
didn't run the vacuum because it would have sucked up these little tiny hair wires here that we wanted to catch
And because those are so light and have so much surface area
those would go up the vacuum and something like this big piece of plastic
would not it fall down through. So at this sample because the non ferrous was, so light and
it had so much surface area we couldn't separate very well by it by just using the vacuum.
This is the steel fraction here, and
it had pretty good separation,
every once in a while there's a little piece like this that still had some copper wrapped up in it but
the interesting thing about this sample is
because there's no large steel in it large shafts or big pieces of steel you actually get away with running a smaller slot or maybe
even a
hole and you probably liberate more copper. We have the half inch slot that's all we had at the time so I'd even say a
3/8 or maybe even a quarter inch slot and you liberate pretty much all the copper at that point. So we're going
to take this and run it on our PCB
processing system. We ended up running about 40 pounds and it's about 2/3 steel and about 1/3
copper for you guys and information. So let's run it through our
PCB system and to see how it goes
So here's our number three bucket and I'm not quite sure how much copper is going
to come down to number three, so we're going to
treat this as kind of a middling fraction and if we have to we can rerun it through the system
to help get the copper over and separate the paper and plastic from it. And here's the number one and number two we're gonna capture
hopefully clean copper in these two ports. And there's a little bit of contamination from our
residual boards in the mill and in the system. So we may get a little bit of residual
fiberglass on board material and these number one and number two,
that's just residual, so if we can look past that and look at the wire
hopefully we get the wire clean of all the plastic and paper from
our sample of motors we ran.
So here's the results of our wire through the PCB system and as mentioned earlier there's a little bit of contamination in here from
boards
but, you can see I combined the number one the number two
and it's pretty much all
metal. There's a little bit of brass in there and his sample actually had a little bit of boards some boards in there too so...
But there's all the metal fraction and this is the number four
And also it's
contaminated by some board stuff but I think a lot of that yellow stuff was the plastic off little transformers and the black plastic
from, some of these little motors and stuff
There's hardly any copper in there so I think you did a really pretty good job separating the copper and the
plastic. So I hope you guys enjoyed the video, thanks for watching and we'll see you in the next one.
