Hey guys, my name is Jason with Mount Baker Mining and Metals, and today we're
going to be running some samples through our new 34 by 24 scrap hammer mill so
let's get it fired up and check it out.
So here are those two alternators and starters that we put in and really the
only reason to pre-shred those is to take out this big steel, these big pieces of
steel really hinder your ability to finally shred this up and liberate the
copper in the steel. And so by pre-shredding you can liberate all the big
steel, have someone on a picking conveyor picking it out and then have all this
stuff go through one of our smaller scrap lines with a much smaller screen
and all of this copper and these small steel plates and the cast aluminum can
be liberated and then separated by a magnet and you can get the ferrous and
non-ferrous separated. So that's why a good example of why you would pre-shred
Motors, alternators, starters, anything with big pieces of steel to get that out and
then you can further process this with another machine. Okay so here's our dirty brass that went
through the hammer mill and if you run this under a mag belt and you get
somebody pickin' you can clean up a lot of clean brass from from all that
stuff it wasn't worth very much. So here's our cast aluminum through our bigger hammer mill,
and again, this was through a four inch square hole but you can see it
broke up the cast aluminum off that motorcycle wheel here, the springs and
stuff, there's stuff out of the chainsaw housing you can see here, there's that
little electric motor that came out of that Sandra that we liberated. And so we
broke up and liberated - there's that piece of steel off that that car part -
but we liberated a whole bunch of clean aluminum now that can be sorted, picked,
and we've upgraded the value quite a bit. So here's those PC towers, and we've got
all this steel came really pretty clean and then we've got all the pieces of boards
and small wires and stuff so that broke them up pretty good. And then
surprisingly all the casing material and steel around the power supplies, it
really came out nice and clean. Get it out with the mag separator, and there's
probably some handpicking here to be done, but it really separates all the
different components really quite well. So here's our transformers, and we ran
through a four inch hole in this situation is a pre shredder so now they
can be run through a smaller hair mill across the mag belt. But the other option
would be put a smaller screen in this hammer mill so you can run a large
single piece but then have it liberate and and separate all the copper and the
steel from each other and then run it under a mag belt.
I think the biggest transformer we ran today was about 20, 22 pounds so we can
actually you know run a large piece of scrap metal all at one time
through a one inch screen, liberate all the copper and steel, and it's a one-pass
system. So I wanted to take a minute here and go over our new 34 by 24 inch hammer
mill and the measurement on that is a 34 inch swing of the hammers and then the
case is 24 inches wide. And we've been hearing from a lot of guys over the
years that they really needed a larger machine than our 24 by 16 inch hammer
mill because they wanted to do larger meatballs, larger transformers, computer
towers, things that were either just bulky or that weighed up to 15 to 20
pounds and so we designed this larger hammer mill for that. Right now, and for
our demonstration today, we showed it as kind of a pre-shredder with a large
screen, four inch holes, to just beat up the stuff, liberate as what we could, but
really the primary goal of a pre-shredder is to liberate some of the
larger steel pieces such as the shafts the larger pieces out of those
transformers and starters and alternators that you can then pick out
before they run into a smaller machine such as our smaller 24 by 16 inch scrap
line. So this unit is powered by a 100 horse electric motor, and then across
here the feed side is about 12 feet high and so for this demonstration we fed it
by hand, but in a real production environment
you'd have a feed conveyor going up and feeding the hammer mill and then the
material would come down through and we have this the chute here that will
discharge also on to a conveyor belt that you could mount a magnetic
separator over or carry the material off to some picking conveyors so guys
could manually separate the material coming out of the hammer mill. So we've
taken the cover off the hammer mill, and there's the screen, those four inch holes.
And this is the rotor, and we have two rows of hammers here's one row and the
other rows on the other side. But this row has three and then on the other side
there's four hammers that are staggered, they're offset from these three. And
here's the hammers were using, they're a manganese steel. And there's a
discharge chute down there. So there's the inside, I believe this is a five and
a half or six inch shaft, big double spherical roller bearings here, and the
whole mill has armor around the outside of the case so that you can
replace it once it wears. And when stuff goes in it just gets beat up comes out
the bottom. So just real quick I wanted to show you guys here's an example of
our 24 by 16 inch scrap line. This is our heavy-duty 24 by 16 inch hammer mill,
discharges down on to a conveyor belt, and then the material comes up the
conveyor belt under a magnetic separator. And you can set the system with the
larger hammer mill up in exactly the same way, I just wanted to give you guys a visual
example of what we have for our smaller systems and how you can set up the
bigger the bigger hammer mill. And in future videos we'll have the complete
line setup so you guys can see the whole process from start to finish.
So I hope you guys enjoyed the video today of our new 34 by 24 inch hammer
mill. We ran several different samples that we get
asked a lot about from customers, but if you guys is the viewer have any samples
you'd like to see run through our bigger hammer mill, please let us know by either
a phone call, an email, or you can leave a comment on this video. So I hope you guys
enjoyed the video, thanks for watching and we'll see on the next one.
