This is one of our 10 x 16 jaw crushers, it’s run from a 20 horse electric motor, and we power it with a 30 kilowatt generator. Here are the jaw plates, high manganese steel, so they work harden over time. We put hopper on top, because most of the rocks we’re crushing tend to pop out. This unit weighs about 6,000 pounds. We can put it on a stand for you. Right now we have it welded to a couple stout saw horses, for a trial run. We’re going to go take a look at the back of the jaw crusher now and I’ll show you how to adjust the jaw gap, for the discharge size.

This big threaded rod pulls a wedge up underneath, which pushes this toggle plate forward and pushes the jaw forward into the stationary jaw. Conversely, if you loosen this, push it down, the wedge falls down, and this whole mechanism slides back and opens up the jaw plates for a larger discharge. This is the tensioning spring. It goes all the way through and connects to the bottom of the movable jaw plate. And as you open the jaw gap up, you need to tighten this, to keep tension on the jaws. And as you decrease the jaw gap, you need to loosen that, because that pulls this rod in which tightens the spring. This 10 x 16 machine will do between 5 and 20 tons per hour, depending on the jaw gap.

Right now we have it down to about one inch minus. Here’s the discharge. it’ll open up all the way to about three to three and a half inch discharge. So you can get a wide range of sizes, and depending on the size you want, you can run more or less through. Alright we have some broken concrete here, and we get a lot of calls from guys that are interested in buying our crushers for concrete demolition. And our 10 by 16 will take about as big a piece as you can hand-feed into it. Anything that’ll fit down those jaws will crush.

So I’m going to hand load these in, and some of them are maybe upward of about a hundred pounds, so I’ll see if I can get them up there to the jaw and show you how it works.
