hey guys my name is Jason with Mount
Baker Mining and Metals, and today I
wanted to demonstrate one of our 6x30 jaw crusher modules specifically
designed for granite and decorative
stone waste. So it starts with the orange
hopper behind me, it can be loaded with a
tote or bin of scrap material. The hopper
vibrates the material at an even rate
down into the 6x30 jaw crusher here,
which is powered by a diesel motor. Once
the material is crushed it falls down
onto this conveyor belt, which can carry
the material up and stack it into a pile,
a box, or a bin for later use. So let's
get this thing fired up and we'll see
how it goes.
So here's the material we crushed, the
last couple pieces where some of that
man-made quartz you can see that crushed
up pretty nice. And we crushed the whole
barrel, I don't know, and maybe five
minutes. So you can see from the video
that it really crushes the stone
pretty good. So I wanted to show you guys
the startup operation for the diesel. So
you turn the key and, once the glow plugs
shut off, you can start the diesel. The
throttle here can be adjusted in or out
for the correct rpm. We found that
running about 15 or 1600 rpm on the tach
is just about right,
which equates to about 275 to 300 rpm to
the jock crusher themselves. And then around
here is the clutch mechanism And so once
the RPM is correct on the tach for the
diesel motor, you can come around and
slowly engage the flywheels on the jaw
crusher and once those start spinning
around you can fully engage the clutch
and get full power to the jaw crusher itself.
So let's go around we'll take a look at
the electrical. So this customer wants
the unit to be mobile and also he
doesn't have three-phase power at all of
his locations, so that's why we have the
diesel power in the jaw crusher. But then
we have a phase converter here so that
he can run single-phase power in and
then three-phase power to the motors. And
we have three different motors, the
conveyor, and then the two vibrating
motors which need three-phase power and
so the phase converter takes care of
that. So now let's go take a look at the
adjustment to the vibrating hopper. So
the vibrating hopper can be adjusted two
different ways - there's a fine adjustment
here on the phase converter itself and
the Hertz can be adjusted up or
down to adjust the vibration of the
motor. For a coarser adjustment, you can
come back here once the machine is off.
Take off the covers of the motors here
and you can adjust the weights on the
motor shaft themselves to get a coarser
adjustment to make it shake harder. When
these are
wired up correctly the spin is opposite
each other which forces the material
towards the jaw crusher. If they're both
spinning the same way, the material won't
move so they need to be wired to
opposite so that the material gets
pushed into the jaw crusher itself. So
now we'll go take a look at the jaw
crusher maintenance. Now we're looking at
the back of the 6x30 jaw
crusher and we can go over some simple
things. Here there's grease fittings here
along the back of the movable jaw and
one over there. And greasing about once a
day is fine and when the machine is new
you want to make sure that you build up
a bead of grease here which creates the seal
and keeps the dust out. So in the first
couple days operation, make sure that a
bead of grease is built up here. It
doesn't need to be flinging off the
shaft, but that's what creates the seal
for the bearings. To adjust the jaw gap,
these plates are spacers which push out
the shuttle and the toggle and
conversely drives the jaw plates forward.
So to increase the gap, you would take
out some of these plates which would
pull all this back and open up the jaw
plate. After that's done this is the
tensioning rod. This either needs to be
tightened or loosened, depending on the
adjustments the jaw plate. If the jaw
plate is opened up, this needs to be
tightened to keep tension on the whole
assembly back here so that it's not
flopping around. These bolts here and
here keep tension on the plates, and if
you are gonna add or remove plates you
loosen these bolts and this large bolt
pushes the whole mechanism forward then
you would back this off a couple turns
so you could pull these plates out. So
that's in a nutshell how you adjust the
jaw gap and the easy maintenance on the
6x30 jaw crusher.. The conveyor
maintenance is pretty easy, there are six
bearings on the unit. There's two here on
the idler pulley, two in the tail pulley,
and two in the head pulley. And the one
other thing you want to keep an eye on
is the
gearbox, there's a little sight glass on
the far side for the oil level. So just
make sure the gearbox has oil and
there's no weeps or leaks out of the
gearbox. So I hope you guys enjoy the
video of our 6x30 jaw crusher
module. If you have any questions or
comments, you can give us a call or send
us an email, all of which is in the
description below. So thanks for watching
and we'll see on the next one.
