The J-3120 is our largest compact Crusher, designed for both mobility and power. It is small enough to fit inside a container for transport but strong enough to withstand the toughest of applications. This crusher features a pair of 31" ✕ 20" single toggle jaws that can be adjusted hydraulically down to 1 3/16" (30mm). There is also a feed sensor, or "magic eye" above the jaws which is used to start and stop the vibrating feeder to prevent blockages and keep the machine running at maximum efficiency.

What customers say about us
Herman Ward
Machinery Partner are great to work with. Equipment is great too, I've crushed concrete, asphalt, cinder block and brick from the day I got the machine.
Tony Lagman
Dealing with Machinery Partner on our shredder was the most pleasant process we have ever had with purchasing machinery.
Tony
I couldn't be happier, that is exactly what I pictured in my head
Jim Sanders
Pretty satisfied with the brand, we use our machine to move clay. If we were to source a new conveyor I would source through MP again. MP support has not been needed because the delivery and everything went as planned.
Gabriel Montalvo
We have had a good experience with our crusher. I crush granite, stone, concrete, brick. It crushes pretty fast and the machine is still working pretty good. I recommend Machinery Partner.
Fabian Afanador
Machinery Partner is a great company. I haven't had to do much service to my machine yet. The J-1910 is a good small machine for a starter set up. For the next 2 or 3 years, this ARK machine is perfect for my operation.
Eric Cook
Working with MP has been a good experience, I would work with MP again for a future purchases. Very reliable machine, it does everything i need it to do and more. It gives me a lot of extra business. The machines functionality is flawless.
Ben Hester
Machinery Partner has been great to work with. They get me answers as soon as I ask. I have had an excellent experience with Barford. All of the machine information provided was accurate
Arthur Smith
We like our machine and have been using it. We have put a couple hundred hours on it and it is running fine! We have had no problems at all. The machine is nice and compact and does what it should. We crush concrete and rock.
Amos Espinoza
Yeah, I'd definitely recommend Machinery Partner to someone looking to purchase a crusher. The 2716 for me is perfect for what I'm using it for, but it really depends on what you're trying to do. I'm planning on upgrading with Machinery Partner in the next year or two.
