Hi I’m Jason Gaber with Mount Baker Mining and Metals, and today we’re going to run
a test for a customer through the scrap line.
This is some metal shavings from his machine shop, and it’s a bunch of cast iron shavings,
mixed in with some brass and a little bit of stainless.
We’re going to run it through the hammer mill to break it all up, run it under the
mag belt to pull the magnetics out, and we’ll get the non-ferrous at the end.
This is another sample we’re going to run, these are some larger turnings and stuff.
This is all mild steel and then stainless, and it’s all rat-nested together so
we’re going to try and put that stuff down the hammer mill as well, see if we can break
it up enough to separate the ferrous and non-ferrous and we’ll see what we get.
We’re going to be running our material down the 24x16 hammer mill.
It has a half inch by three and a half inch slot in the screen, and come out onto this
discharge conveyor, go up under the magnetic cross-belt here, all the magnetics are going
to come out there, and the non-ferrous is going to come out here, down through our zig-zag
which we won’t be running.
That’s for dust collection and another recycling process.
But the non-ferrous will end up in that bucket.
Here’s the results of our cast iron and brass shavings.
This is all the magnetic stuff here that got pulled out.
Here’s the clean non-ferrous, and you can see it’s mostly brass, a little stainless
here.
But we actually ran this through the magnet a second time and didn’t get any further
magnetics of it.
So this came really pretty clean.
Okay so here’s the result from our blue trash can full of turnings.
And it’s a little bit harder to tell with this stuff because it’s more fresh, but
this is all the magnetics.
And over here in this bin is all the clean stainless turnings.
And again, we ran it through a half-inch screen, and that may be a little bit too big, you
may want to go three-eighths, you may want to do quarter inch punch-plate hole, but the
idea is pretty sound: separating the magnetic turnings from the non-magnetic.
So thanks for watching, and we’ll see you on the next video.
