The Barford 750J is a compact jaw crusher with some features that make it ideal for working in built up areas, or moving from site to site.
This crusher has a pair of 28" by 20" hydraulic jaws that are reversible. So if you get any material stuck in between them, you aren't going to have to break down the machine. You can just put the jaws in reverse for a bit to release whatever is stuck in between them, and carry on working.
It's got a 60hp motor, but is also dual power, so if you want, you can run this machine entirely off a mains connection. This is going to be great for conserving fuel or if you're working in a built up area and need to keep noise down.
The 750J has a vibrating feeder that pushes material along at a nice constant speed. It also has a feed sensor to control the material flow if it's getting too quick for the machine. Overall, this provides a consistent flow which makes the machine crush really well.
This machine is great for crushing concrete, which you can see in the video below, but it's also ideal for processing asphalt, demolition materials, and recycling waste. If you are crushing something like CMD that might have metal or rebar in it, there's an overband magnet above the main exit conveyor, so you aren't going to damage a screener or impact crusher that might be working after the machine, by throwing a piece of metal at it.
What's really impressive about this machine is its size and weight. It weighs less than 10 tons and has a transport width of less than 8 feet. That means it can fit inside a standard 40' container while still having some really respectible crushing power. This is great if you need to get your crusher into sites in built up areas, or just gernerally move your machine around a lot.
It's also on tracks, so with the help of the umbilibal remote that's attached to the machine, you can drive it straight on or off a trailer and be crushing within 15 minutes of getting to a site. As well as the wired remote, there's another wireless remote that can be used to control the jaws, so if you're loading this machine from an excavator, you can also control it right from the cabin.
Optional extras include;
- Dust suppression kit ($1,000) - So if you're working with particularly dusty material this can help prevent dust clouds forming which can be bad for your health and also make it harder to see what you're doing.
- Fines belt on 180° swivel ($9,950) - used to carry fines that are falling through the vibrating feeder away from the main conveyor, so you can process the rest of the material quicker, and you also get a nice fine product out the back of the machine that you can also sell.
- Tines/Finger screens in the feeder ($500) - These are going to stop some of the smaller material getting into the jaws, so it can process those bigger chunks a bit easier.This means you can be a bit less picky about what you're putting into the machine and can load it up with a mix of finer and larger material.
