Kleemann at Conexpo 2014: World and American Premiere in Contractor Class

GÖPPINGEN/GERMANY, February 18, 2014 - Kleemann presents its completely new generation of Mobicat EVO mobile jaw crushers to the American public for the first time at the Conexpo trade fair in Las Vegas. The radical redesign of the successful EVO mobile impact crusher series is also celebrating its world premiere.

With the presentation of the new impact crushers in the Mobirex EVO series at the Bauma 2010 trade fair, Kleemann laid the foundations for a generation of plants which sets new standards with regard to output, efficiency and versatility in the contractor class. At the Bauma 2013 trade fair, Kleemann went one step further in the form of the Mobicat MC 110 EVO mobile jaw crusher, which has also been completely newly developed, and was presented there to the public all around the world. The American premiere of the MC 110 EVO is now due to take place, where in addition to the further development of the Mobirex EVO series mentioned above, the new Mobirex EVO 2 series is celebrating its world premiere.

Mobile MC 110 Jaw Crusher: Complete Redesign

After Bauma 2013, the new MC 110 was launched in a number of European countries. "It has been shown that the concept works. Output, consumption, flexibility and availability – everything that customers in this sector expect can be performed by our new jaw crushers to the highest standards," says Mark Hezinger, Head of Marketing at Kleemann. He is convinced that both existing and new customers in the USA will also be enthusiastic about the advantages of the plants. "Such a wealth of innovations, such as the direct drive with electrical drives for the vibrating chute, pre screen and the conveyor belts, the innovative CFS loading control, the effective pre-screening, and the new crusher unit with a hoisted articulated crusher jaw, to name but a few, cannot be found in any other plant in this class," Hezinger went on to say.

Mobirex EVO 2 mobile Impact Crushers: efficient and versatile

After four years, Kleemann has consistently developed the Mobirex EVO series at a number of important points. The fundamentally outstanding material flow which is characterised by opening system widths and therefore unrestricted system component transitions, was able to be further improved by the new Continuous Feed System (CFS), as it is also used in a similar way in the MC 110 EVO. Overloading is detected using various parameters and the material conveying speed is regulated accordingly. Therefore, as a general rule, the conveyor elements do not come to a complete standstill (vibrating feeder and pre screen) and continuous loading of the crushing unit is ensured.
The optional oversize grain return conveyor has also been redesigned. Thanks to the bend-free conveyor and the transfer chute integrated at the feed hopper, operational safety when working with inhomogeneous materials is increased enormously and the range of applications is therefore expended even further.

Easier Transport thanks to the Hook Lift System

Thanks to the new conveyor in the oversize grain return conveyor, the ground clearance in the area of the optional screening unit was able to be significantly increased. In this way, driving the plant with an attached screening unit onto a drop-centre loader is considerably easier. In addition, the screening unit is equipped with a "hook lift" system, which enables the unit to be easily transported separately.

High Levels of Output and Efficiency

The drive concept remains the same, with the crusher driven directly via fluid coupling and electrical drives for the vibrating chutes, screens and conveyor belts. In terms of consumption per tonne of material, this principle is certainly hard to surpass. In addition, the familiar effective pre-screening is carried out by the independent double-deck pre screen, for which replacing the screen lining in both the upper and lower decks has been made significantly easier. Furthermore, the plants are available with crusher inlet openings of 1100 mm (MR 110 Z) and 1300 mm (MR 130 Z), which provide feed capacities of up to 350 or 450 t/hour.

New Exhaust Emission Legislation

All four Kleemann crushing plants presented at the Conexpo trade fair comply with emission standard 4f as specified in the USA (Tier 4f). To identify machines which comply with this emission standard, all machines from the Wirtgen Group bear an additional "i" in the type designation; the official names of the plants exhibited at Conexpo are therefore "MR 110 Zi / MR 130 Zi" or "MC 110 Ri / MC 110 Zi".
