The most recent addition to Anaconda’s crushing division is the all-new I12-R Impact Crusher. According to Anaconda, the I12-R is an expression of its engagement with dealers and end users. Thus, leading the company to an understanding of the feature and specification requirements for the market.
The I12-R is a mid-size impact crusher that Anaconda believes will reduce feed material requirements, foster continuous production and produce consistent shape.
The purpose of this design is predominately quarrying and recycling applications. It features a 43’’(1090mm)-diameter 4 bar rotor on a 45’’(1140mm)-wide Universal Crushers Impact Chamber.
The I12-R is features a large hopper area and an aggressive vibrating pan feeder with a two-tier grizzly section. This helps facilitate movement of the feed material toward the impact chamber.
Furthermore, this grizzly section stops fines and smaller dirt from entering the chamber by discharging it onto the side dirt conveyor.
Also, available as an option is a pre-screen before the chamber. This option aids in fines removal, reducing unnecessary wear on the chamber.
In collaboration with Cummins, Stage 5/Tier 2 Cummins L9 Performance engines power the I12-R.
The new after-treatment system utilises selective catalytic reduction and diesel particulate filtering, which eliminates Exhaust Gas Recirculation (EGR).
According to Anaconda, removing EGR makes installation and maintenance easier and allows for an increase in power and torque.

Improved fuel consumption and low noise emissions also allow the I12-R to work in urban or restricted areas.
Additionally, Anaconda added a double-deck screen box after the crushing chamber. This feeds into either the auxiliary recirculation conveyor or the tail conveyor to join the finished product.
Also, the recirculation screen is detachable, which converts the machine to a standard I12 unit.
Anaconda Managing Director, Alistair Forsyth has said, “The Anaconda I12-R comes outfitted with a 43 (inch) x 45 (inch) McLanahan Universal Crushers Impact Chamber. The 14ft stepped deck Vibrating Grizzly Feeder can be fitted with bofar bars, fingers or punch plate, along with a bottom deck mesh to pre-screen the material before it is fed into the crusher chamber. The 4 bar variable speed 43” rotor delivers high performance impact crushing in a variety of applications. The I12-R comes complete with a double deck screenbox that allows for both the top and bottom deck material to be fed back into the returns conveyor to maximize the screening performance or alternatively for the 2nd product to be discharged either to the side of the machine or onto an optional discharge conveyor.”
Anaconda Crushing Engineer, Barry McCullagh added, “The Anaconda I12-R combines the productivity of the super-efficient unique direct drive Universal 45” impact crushing chamber with the versatility of a full screening and recirculating system which allows operators to produce a crushed and screened product with one machine. The combination of the impactor with the high energy screen and recirculating conveyor offers maximum productivity on a small footprint. The return offers the option to recirculate oversize to the hopper or radial out 90 degrees to stockpile material.”
