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 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 the control cabinet protected by ample anti-vibration cushioning. 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. The MCO 9i’s Continuous Feed System (CFS) connects with a Kleemann jaw crusher, controlling the feed to the cone. 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, 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. Kleemann is a Minerals Technology brand of Wirtgen Group, the internationally operating group of companies in the construction machinery sector incorporating four traditional brands: Wirtgen, Vögele, Hamm and Kleemann. Kleemann’s product brand names are the Mobicat mobile primary jaw on crawler chassis with feeding unit, pre-screen and conveyors built in various sizes ranging from 221-1,100 tph capacity; the Mobirex mobile primary impactor on crawler chassis with feeding unit, pre-screen and conveyors built in various sizes ranging from 386 to 772 tph capacity; the Mobifox mobile secondary crushing machines with feeding unit, impact crusher and a screen producing up to three particle sizes; the Mobicone mobile secondary crushing machines with feeding unit, cone crusher and a screen to produce up to three particle sizes; and the Mobiscreen mobile screening units, producing up to four particle sizes with fixed or swiveling discharge belts, with a screening surface dependent on ultimate use.

New Kleemann Plant Marks Commitment to Industry
In early 2010 Kleemann GmbH completed its new headquarters and state-of-the-art manufacturing plant near Göppingen, just east of Stuttgart in south-central Germany.
The new plant marks Kleemann’s commitment to the minerals processing industry and incorporates the highest production technologies for the manufacture of aggregates and minerals processing equipment.
This new “greenfield” manufacturing plant is making Kleemann mineral processing equipment more available, and will speed product delivery in North America in coming months. “With 350,000 sq. ft. of production area and 40,000 sq ft of administration area, Kleemann will excite the market with new models and features for 2010,” said Evan Clarke, vice president.
For over 150 years Kleemann has led the minerals processing industry with design ingenuity, producing crushing and screening equipment for many leading markets. Since being acquired by the Wirtgen Group in 2006, the company has experienced dramatic growth which has led to reinvestment by the group to help streamline production and allow for greater volume for its new expanding markets.
“As Kleemann gathers momentum within the United States and Canadian markets, and new dealers take on the product line, many customers are seeing the ‘Kleemann Advantage’,” Clarke said. “We bring to the market a wide range of track mobile crushers and screens with many unique features.”
The new plant utilizes the most modern German high-tech manufacturing processes, including short internal product assembly lines. On the new 1.34 million sq. ft., site, the new manufacturing facility covers an area of 376,736 sq. ft., complemented with a 43,055 sq. ft. administration building. The oversized interior capacity of the new main production facility accommodates the enormous dimensions of Kleemann’s largest crushing and screening machines.
In the plant’s central warehouse contains two storage zones in which some 10,000 items are stocked. “On average, 200 items with a total weight of 8.8 tons are handled here each day,” said Kleemann central warehouse manager Martin Zemmel. “We really benefited from the know-how of the other Wirtgen Group companies when building our new facility.”
Kleemann’s new painting facility for large parts is one of the largest such facilities in Germany, with a tremendous load-bearing capacity of 33 short tons, and around 21,500 sq. ft. of floor space. Kleemann’s switch-over from wet spray painting to powder-coating not only marks a major step towards boosting surface quality, but also has far less of an environmental impact, with the system far exceeding the requirements of the EU environmental guidelines.
Kleemann’s Roots Run Deep
Kleemann is a newcomer to the North American aggregate processing market, but its roots lie deep. Established in Germany in 1857, Kleemann was acquired by Wirtgen Group in 2006. Today, a growing network of equipment distributors and dealers is enabling Kleemann Inc. USA to boost its domestic profile and serve customers in North America.
Today Kleemann manufactures and markets a broad range of durable, productive mobile and stationary processing equipment and technology for crushed stone, demolition waste and mixed construction waste.
Kleemann’s product brand names are:
• The MOBICAT mobile primary jaw on crawler chassis with feeding unit, pre-screen and conveyors built in various sizes ranging from 100-1,000 tph capacity
• The MOBIREX mobile primary impactor on crawler chassis with feeding unit, pre-screen and conveyors built in various sizes ranging from 100 to 1,000 tph capacity
• The MOBIFOX mobile secondary crushing machines with feeding unit, impact crusher and a screen producing up to 3 grain sizes
• The MOBICONE mobile secondary crushing machines with feeding unit, cone crusher and a screen to produce up to 3 grain sizes, and
• The MOBISCREEN mobile screening machines, producing up to 4 grain sizes with fixed or swiveling discharge belts, with a screening surface dependent on ultimate use.
