Hey guys my name is Jason with Mount Baker Mining and Metals and we get asked
all the time about how long does it take to change our hammer mill screens and so
for today's video, I'm going to change the screen and show you what
tools to use and we'll time it so you can see in real time how long it takes.
So I want to walk through the tools first. All the bolts I'm going to be
loosening are three quarter inch so I'm just going to use a socket and an in
wrench. And then we have a three pound hammer and a piece of steel stock that's
going to help us take the screen out. And then this tool can be very useful as
well it's just a little pry bar. So I'm going to take my phone, get a stopwatch
going... So we'll start our time and we'll see how long it takes me. The first step
is going to be taking the lid off, I got to loosen these four bolts and then
we're going to pull the lid with forklift.
Okay so now that we have the
head off, I'm gonna loosen the armor bolts that hold the screen in. And
there's eight bolts, four on this side and four on this side, and when those are
loose I can pound on the screen here with my hammer and roll it out with the
pry bar.
Okay now all the armor bolts are loose so now I'm going to use this piece of
steel stock and a hammer and just tap the edge of the screen down and it'll
roll the screen out and I might have a helper come in and help me pry up the
screen from this side with the pry bar.
Okay now the old screen is out, I'm going to put the new screen in and do the
process in reverse.
Okay now that the screens in I'm going to put the rubber
gasket back on and tighten down the armor nuts.
Okay so now the four armor
bolts are tight, or the eight armor bolts are tight, so I'm going to put the lid back
on and tighten down the four bolts that hold the lid on and the screen
replacement will be complete.
Okay so we finished our screen change and it took me 10 minutes and 39 seconds.
