Hey guys, my name is Jason with Mount Baker Mining and Metals and today we're gonna
be running our new 34 by 24 hammer mill again doing some tests on it. Today we
have our discharge conveyor and cross belt magnet hooked up so we can run a
full-sized test. We're going to be running three different samples, we're
going to be running a contaminated aluminum sample, whole PC towers, as well
as whole printers. So we're going to run a lot of stuff through and we'll show
you the results.
Okay so here's our crushed up, clean aluminum. See it all came out pretty good, we put it in their clean aluminum bin here.
So they're pretty happy with the results. So we've just
finished our contaminated aluminum sample and I wanted to give you guys a
couple numbers because everyone's interested on how much the value
increase was. And so we ran almost exactly two thousand pounds of
contaminated aluminum, and the value of that is 19 cents a pound, which
works out to be $380 a ton. Now we ran the sample, pulled the steel
out, and we ended up pulling out almost exactly 25 percent weight was in the
steel. So we ended up, if you 2000 pounds, you would end up with
1500 pounds of clean cast aluminum, and today's prices on clean
cast about 37 cents a pound, which equates to 555
dollars for that 1500 pounds. So if you take the difference, we
actually increase the value of the cast aluminum by 175
dollars using the machine behind me, and the runtime for the whole 2000
pounds was about 35 to 40 minutes.
Okay so here's the result from shredding up those computer towers. And I don't
know we probably did 20 to 30 or so, and this is the stuff that went under the
mag belt. The steel has for the most part been pulled out of it. There's some
aluminum pieces off hard drives. Aluminum heat sinks.
But I think this is all the good stuff from out of the towers, and now it can
be further shredded, granulated, may run through an air table, may run through
a water table. But we've taken all the manual disassembly out of the PC tower
so we've just shredded them, got the steel out, and then this is the good
stuff. So well pour the steel out and take a look at the steel fraction here,
but I think this worked great, this is where all the money is in PC towers right here. So here's the
steel fraction from those PC towers, and as you can see, you probably want a picker
here to get some of the stuff that they've got attached to the steel or
something like... like this that probably has a little piece of steel on it that
the mag belt pulled out, there's also another little a little electric motor I
found in there. But hardly any boards in here though the 99% of the weight is the
steel fraction. And then again, if you wanted to get the last little bit out you could have a little picking belt
coming off the mag belt that you can have a guy pulling out some of this
stuff that, you know, does have some value, this one's got those little copper
wound around the steel magnets, the mag belt pulls those out.
As you can see, it came pretty darn clean. So I think it's just fantastic we did
great, the machine works really good for shredding and PC towers.
So here's some stuff I hand-picked just while I was standing there kind of
watching, and I tried to pull out the aluminum heatsink and get those out.
There's actually a copper heat sink in there as well. But this is again just
stuff I hand-picked and it didn't take very long. So I don't even think you need a
picker after the mag belt, where you probably need a picker is for the steel
fraction because there's some pieces like this with a board on them it still
has a little bit of steel that you'll probably want to reprocess and get that
board out. So a lot of our customers have been asking to see printers run through
our hammer mill. So we got a couple printers and a DVD player here, we're
gonna run these through the hammer mill, break them up, we'll run them under the
mag belt, any steel that comes out will get and then we'll see if I can pick out
some boards or anything of value out of these as we're going by there.
Something unexpected when you're running printers is that they crush so fast and
come out so thick on the belt the mag belt fins actually sweep off some of the
plastic into the scrap steel bin and so you'll see on this clip in the next clip
that the material is so thick on the belt that we need to raise the mag belt
little bit so you're not sweeping plastic into the scrap steel.
This is the non-magnetic plastic of the printers, and, boy, for the most part it's all plastic.
There was some copper wire that carried over, some little paper and fluff, some
aluminum pieces, we found the aluminum heatsink in, but majority of this is
plastic from the case. So thanks for watching our video of our new 34 by 24
hammer mill and scrap line. If you guys have any questions or comments, please
let us know our info is in the description below. So thanks for watching
and we'll see you in the next one.
