BR550 is a nice machine for one thing. The onboard computer system. Unfortunately it gets smoked by teh Extec C-12+, I have an Extec C-12+ and a C-10. I can get with the C-12 400mtph. I understand is does depend on the type of aggregate, but the Extec stays at that mark with just about any type of rock. The BR550 that I had on a two month rental (brand new machine) couldn't come close, but all in all the Komatsu was a well rounded machine for a company that just wants a primary crush. Nice video

No problem whatsoever in Granite, basalt, Andesite, greywacke or any other rock type. When you've rebuilt your C12 a couple of times you might come round to some modern thinking. Komatsu are the only manufacturer who has spent any serious money on jaw crusher R&D and improvement for many years now. Metso/Nordberg's C100 design ( the basic design behind every one of their jaws) is 50 years old now with very little change, a good long life crusher, but the 550 will beat it in production

Seriously consider a drive method using hydraulic power with variable displacement pump(s) this allows lower optimal horsepower, lower fuel use and more flexibility in operation - like starting under full load, variable speed etc. Or just buy a Komatsu? We have plenty available. cheers

: I see you're designing your own crusher? If you use an engine and belt or PTO drive, make sure you are well overpowered then you can have the advantage

of being able to vary your jaw speed to suit the material. The downside is a much higher fuel use with the higher available horsepower above optimal

[rasersedge2004]

The BR550JG-1 allows you to optimise the speed of the jaw to suit those variables based on what you can actually see going on in the crushing chamber and the available torque/power is not reduced as the speed is reduced. Faster jaw movement will cause more wear and strain to the mechanism and is quite often not rewarding you with more production. Again, depending on what you're crushing.

[rasersedge2004]

We're not crusher designers, but you're right, we do have broad experience with many kinds of crushers and many opportunities to compare makes and models. The optimal breaker speed varies widely according to the properties of whatever it is you're crushing.

[RenzeZielman]

You guys seem to have broad experience with crushers: Can you explain me what the optimal breaker speed is ? Is faster jaw movement allways giving more output ?

[rasersedge2004]

Does it really get any better than this in a machine only weighing in at 47 tonnes? I had a 51 tonne Nordberg LT100 which I thought was pretty good getting 290mtph in these same boulders but with a 200mm OSS. Boulders averaging almost the maximum size are never easy because its hard to get a continuous flow into the jaw but the BR550JG seems effortlessly able to achieve it. That jaw setting at 100mm OSS is quite tight so the production you see amazes me. Am I happy to offer it? You betcha!
