What is the Difference Between a Jaw Crusher & an Impact Crusher?

Do you know the difference? Bob with Rebel Crusher explains this and more!

Welcome back to Rebel Crusher and today we’re going to be answering a question from Justin. It doesn’t say where Justin is from but this particular question looks like it really doesn’t matter where he’s from. 

 

So, what is the difference between a jaw crusher and an impact crusher and why would I use one over the other? 

 

So, Justin we hear that question all the time. You know people are you know they hear one thing over another and in general it has to do with what material you want to produce and what you’re actually crushing. So, with let’s say an impact crusher for example we typically use that to pulverize make very, very small product that you can imagine an impactor is in the name, right? It impacts the material, it explodes it. So, we’re not putting granite in an impactor, we typically don’t like to put steel in them. More than likely we would use an impactor in softer material, application possibly asphalt where we’re looking to grind up asphalt really, really small. Otherwise in most other applications where we’re crushing concrete with rebar, rock, sand and gravel, most asphalt you know bricks, block anything like that the Jaw Crusher is just so much easier to operate. Less dust, less maintenance, the wear parts are less expensive, you’re changing them less frequently. So, in general the impactor is something we use only for a specific application. We’re grinding up gold, we want to make a bunch of powder, we’d use an impactor and we might even use a jaw ahead of it so the jaw would take the brunt of it and then feed it into an impactor. But just vice versa you know looking at the differences the rule of thumb in general is if you can crush with a jaw don’t use an impactor. So, we’re only really bringing that impactor into the equation when we absolutely have to. And I’m sure I’m going to get some heat from that. People will say oh that’s not true we can use our impactor for this and that, yeah, well possibly you’re right but at the end of the day almost any expert would say if you can use a jaw and it makes the product you want, use the jaw. Slower speed, kind of slow and steady, it wins the race kind of thing, jaw is running around 250 rpm, they’re squeezing the material together and letting it go down whereas the impactor is exploding the material, runs around 1000rpm. So, just use your common sense; which one would you rather run? Which one would you rather have if by accident your guys threw a manhole cover or an anvil or let’s say a fire hydrant and by the way we’ve had tons of clients that have sent us e-mails hey my rebel crusher just ate a toilet bowl, a transmission by accident and it’s still kept going. So again, the jaw we have both, Rebel has an impactor and a jaw, so I’m not pro one or the other, I’m more interested in the product you want to make. 

 

So, hope that answers your question, feel free to give us a call we’ll go into more detail. So, thank you very much.

We hope you’ll enjoy it as much as everyone else did!

 

Carolina CAT held a Rebel Crusher product demonstration event on May 10. Approximately 60 people from 25 area contractors attended the event.

The Rebel Crusher is able to produce a finished product. The machine has the ability to make up to four screened products at the same time. Rebel’s crushed material can be used in place of quarry crushed stone. Uses also include pipe bedding, driveway bibs, home garages, decorative stone and landscaping applications.

A large feed opening reduces material preparation time. The Rebel Crusher produces high quality products without excessive fines.

The Rebel Crusher has the ability to swap from a jaw crusher to an impact crusher or vice versa in a matter of hours. Pre-screen and finish screen ensures quality products are produced.

The Rebel Crusher can tackle many applications. It has the ability to pre-screen, crush and separate crushed material into four separate stock piles while removing rebar, wire and steel at the same time. The Rebel Crusher can track and crush without stopping. The Rebel can crush and screen asphalt, concrete with or without wire and rebar, brick, block, most rock, sand, clay, glass and more. The Rebel can track into the middle of a city and is inconspicuous. The unique discharge conveyor heights are deliberately lower to minimize dust production. The fuel efficient diesel engine is quiet and is able to power up to three additional conveyors.

Variable speed, low feed height, heavy duty feeder, features “mine duty” impact idlers with 4140 oversize steel shafts specifically designed to handle being continuously fed large chunks of material. When dumping, the feeder absorbs the shock load, producing very little dust and reduced noise. Having the feeder on an angle allows the loader operator to see what is in the Feeder/Hopper. No need to build a ramp or have a huge machine to feed the Rebel.
