Nashville, Tenn. – The new Mobicone MCO 9i EVO/MCO 9i S EVO mobile cone
crushers from Kleemann offer aggregate producers high-productivity secondary or
tertiary crushing in a fuel-efficient, Tier 4 Final emissions-compliant
machine.

The S-version of
the MCO 9i EVO provides a discharge conveyor-mounted final classifying screen
with oversized aggregate return conveyor. This permits a closed material cycle
and production of final particle sizes without a stand-alone screen. The
oversize can be optionally discharged via the swivel-mounted return conveyor at
the side.

In lieu of
hydraulic drive, the MCO 9i EVO/MCO 9i S EVO’s diesel-electrical drive provides
low fuel consumption in a compact design. Optional crusher anti-spin and
automatic lubrication functions make for high crushing capacities and equipment
durability. Its power plant generates 332 hp at 1500 rpm.

The MCO 9i EVO/MCO
9i S EVO’s 37 in. cone crusher diameter permits a raw feed capacity of 287 tph,
with a feed size maximum of 8.25 in.

The feed hopper standard
feed opening is approximately 8 ft., 3 in. wide x 11 ft., 2 in. long. With
extensions the feed opening expands to 8 ft., 7 in. x 12 ft., 6 in. Its vibrating
feeder is 40 in. x 6 ft., 11 in.

Like other EVO
mobile crushers from Kleemann, the MCO 9i EVO/MCO 9i S
EVO is driven by a powerful diesel-direct drive, which together with the
electric drives of the conveyor belts, ensures very efficient operation with
remarkably low fuel consumption.

To ensure power is delivered
to where it’s needed, the optimized crusher housing design permits over 287 hp of
the total 332 hp drive to be continuously available to the crusher. In
combination with the large stroke of the cone crusher, this ensures a maximum
throughput of up to 287 tph.

The MCO 9i EVO/MCO
9i S EVO is equipped with the same touch panel control system which has been
proven on other EVO plants, with controls protected by ample cushioning and
positive air pressure which keeps dust out.

The MCO 9i EVO/MCO
9i S EVO presents a powerful and efficient design, and provides an ideal
complement to the new MC 110 Ri EVO or MC 110 Zi EVO mobile jaw crushers from
Kleemann. These machines may be interlinked for maximum production, and their material
conveying elements – such as the vibrating chute or grizzly – can be perfectly
adapted to each other, assuring that the cone crusher always maintains the optimal
filling level and producing a high-quality end product.

With its Continuous
Feed System (CFS), each step the material
goes through in the MCO 9i EVO/MCO 9i S EVO is wider than the width of the one
before it, eliminating choke or wear points. As the crusher is diesel
direct-driven via a fluid coupler, feedback is provided from the engine to the
controlling computer, allowing indications that the crusher may be getting
overloaded.

Thus CFS manages a
more equal loading of the crushing area, in which the conveying frequencies of
the feeder trough and the prescreen are adapted independently of each other to
the level of the crusher, significantly boosting performance. At the same time
the exclusive CFS maintains a choke feed to the crusher, eliminating stops and
starts of the feed system, improving production, material shape and wear.
