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 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 IV 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 1,500 rpm.
The MCO 9i EVO/MCO 9i S EVO’s 37 in. (94 cm) cone crusher diameter permits a raw feed capacity of 287 tph (260 t), with a feed size maximum of 8.25 in. (21 cm).
The feed hopper standard feed opening is approximately 8 ft. 3 in. wide by 11 ft. 2 in. long (2.5 by 3.4 m). With extensions the feed opening expands to 8 ft. 7 in. by 12 ft. 6 in. (2.6 by 3.8 m). Its vibrating feeder is 40 in. by 6 ft. 11 in. (101 by 2.1 m).
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 efficient operation with 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, according to the manufacturer.
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 a 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 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, according to the manufacturer.
