Hi, my name is Jason with Mt. Baker Mining and Metals
and today we are going to do a jaw crusher test on some of this material here
This is some stone product that a guy sent us
that's a fresh face
We have a couple different sizes here, this is the smaller one and this is the biggest one
We are going to feed these down a 6" x 10" jaw crusher
this one right here behind me
The goal is to get the product as small as possible
We ran a little test pass here earlier
and this is as small as we could get it
it's probably half inch minus with a lot of it will probably be
less than quarter
We will run some samples, do some screening and show you how it works
Here are the results of one pass through our 6" x 10" jaw crusher
it was as tight as the jaw plates could go, so this is the finest you can get out of a 6" x 10"
This is the 1/4" minus
there is 17.25 pounds of this material
The next size up was quarter to half inch and we got 18 lbs of this stuff
and this is the 1/2" to 3/4" and this was the biggest fraction we had.
and again about 18.5 pounds of that
across these three size ranges the distribution is pretty equal.
we are going to take the oversize 1/2" plus and re-run it through the jaw crusher one more time
and we will re-screen and see what the distribution is
if you take the oversize and run it one time through again
choke feed it, put it all in there at the same time and hopefully get a finer crush
Were going to re-run our oversize
our 1/2" and bigger
I will re-screen this and see what we get
This is the oversize material from the first run
that we ran through the jaw crusher again and re-screened it
ended up with 3.5lbs of 1/4" minus
8lbs of 1/4" of 1/2"
and than 5lbs of the 1/2" to 3/4"
and we lost a little bit, it didn't all make it in the bucket
and that's why it doesn't add up to 18lbs
we started with 54lbs of material
and we ended up with 5lbs after two passes through the jaw crusher so we got 90%
1/2" minus with a two pass through the jaw crusher so that's pretty good
thanks for watching our video
feel free to send us sample or call us for more information
and we will see you on the next video, thanks!
