Hey guys, my name is Jason with Mount Baker Mining and Metals and today we're gonna
run this whole bin of contaminated brass through one of our bigger hammer mills
and under mag belt. This is one of our 34 by 24 inch hammer mills and we're feeding by
hand in this demonstration. Inside the hammer mill is a four inch square screen
that crushes the material down to size, discharges under this conveyor, and then
moves the material up under the magnetic cross belt to pull out steel, and they
can be hand-picked the waste aluminum stainless, can be hand picked out and the
clean brass can go up there and into a bin. Here's the magnetic cross belt and
you can see that the steel jumps right up off the conveyor belt and is pulled
off into the steel bin. And I've been really surprised at the small size of
steel this thing can pull off, so it's really very efficient at recovering
steel out of the screened brass.
So I was the one picking the waste and stuff off of the belt and I was doing
two things, I was picking off the aluminum, the stainless, anything that was
not clean brass, as well as copper and anything of higher value I was throwing in
a different bin. So not only was I getting the waste out of the stream but
I was also upgrading as well.
So here's what we got out of that bin of contaminated brass we ran. And we got a
barrel full of the clean brass, the stuff that went into the mag belt, and then we
we picked it and got all the, tried to get all the aluminum and the stainless out. We got
a barrel of copper... the lights bad but there's our clean copper. And then this
is a barrel of miscellaneous stuff, aluminum, stainless steel, plastic hoses
stuff like that. And then over here this is the steel fraction that
the magnet pulled out. And we went through and we we picked out some of the
steel that had brass still attached to it and reran it and it all came pretty
clean so this is the, this is the steel fraction from that bin of brass and the
whole bin weighed about seven ton - 1750 pounds, and
so we'll take it back and get all our different fractions weighed up and kind
of see what we got. Okay so I just wanted to go over really quick the numbers from
that brass we ran. We ended up running a total of 1705 pounds,
and if you're a scrap yard, the scrap yard can solve that for about
75 cents a pound right now, which is not a very good price. So the total value
is going to be 1278 bucks. This is the stuff
after we processed it, the clean brass and clean copper is where the value was.
We had a little bit of contaminated brass, mostly some reversing valves and
some other things that we couldn't quite get clean with that four inch screen so we
just took them back as contaminated brass. Here's the breakdown by
percentages, but what you'll see at the bottom here is after we process that
1705 pounds, we ended up with a value of about 2148
that the scrap yard could sell once it was upgraded to clean brass and clean
copper. So that was the value of about 870 dollars, it
took us about two to three hours when you factor in the handling and the
moving stuff around and get cleaned up. So it's pretty good return about $250 an
hour for processing dirty brass. And today we're going to be running this
whole tub of brass radiator ends. And these things have a plastic top, a brass
piece here that they cut the fins off, and a steel clip that holds them to the
to the plastic. And we're gonna run them through our hammer mill behind us which
has a four inch screen in it, we're gonna bust all that stuff up, it's
going to come out run under a mag belt behind me, pull those pieces of steel off.
I'm going to pick the copper and pieces of brass off and then the rest is going
to go into this dumpster here which is all going to be plastic and waste.
These brass radiators were actually really nice because they came out in such
large pieces that it was very easy to pick. And actually it came out sometimes
in such large pieces that they got caught on the mag belt here, depends on
the mag belt and were swept into the steel bin. So at the end of the run we
just dumped out the steel bit and got out any of the large pieces of brass
that got swept off.
But you can see in there now there's a few pieces of the brass and copper, we
pulled all those out so it was in the net being just clean steel at the end
that was waste.
Now I'm not an expert picker but this is pretty easy picking, brass and copper was
picked out and any of the plastic just went off the end into the waste bin. And
we ended up with three really really nice clean products, waste, the clean
brass and the clean copper.
Here's some of the stuff that the magnet pulled out, and you can see it's mostly
these steel clips that hold the brass onto the plastic. But there are a
few things like this is some brass with with some steel inside, and there's a lot
of these little pieces like this where there's a little steel net on there and
so there's some dirty brass in here. I'm gonna go through, pick through it, and see
what it looks like for upgrading some of this stuff. And so here's the two bins or
barrels full of clean brass that we got. And we just hand-picked all this out as
it went out under the mag belt and there are still some of these little rubber
gaskets on there. But that it's all been under the mag belt, it's all
clean, and and it should be nice clean yellow brass. Here's the copper we ended
up with from that run. And just like with the brass radiator ends it was all
picked, they're still I can see a little bit of these gaskets on there but this
is all the copper. And I was really surprised there's probably half a
garbage can full of copper here. And then here's our dumpster full of the waste.
And almost all of its plastic, there were a few aluminum fins that I didn't even
bother to pick and I just I just let him go. Aluminum's not worth very much right
now and there were hardly any of them left. There were a few aluminum
radiator ends I also just let go. There's hardly any brass in there at all, it's
all pretty much clean plastic. Okay so here's the breakdown on the brass radiator ends we did.
We started out with for 340 pounds and for the valued scrapyard there was about 25
cents a pound for a total value of $360. After we processed it we ended up with
667 pounds of clean brass, 140 pounds of copper, a little bit of those
contaminated brass ends and things that have the nuts on them. And here's the
percentage breakdowns, but this is what's really a shock to me we
ended up with a value to the scrapyard of about 1450
dollars, which is almost an 1100 dollar difference in the value
when we started with and the value after we broke it down with a hammer mill and
picked all that good stuff out. So you can see this was well worth doing and
again it only took in that two to three-hour range so we were making
pretty good money there for our processing. So I hope you guys
enjoyed the video of our larger scrap hammer mill processing samples. If you guys
have any questions or comments about what you saw today in the videos you can

see on the next one.
