Kleemann at the Conexpo 2014: World and American premiere in the contractor class

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 completely 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. Kleemann is now going one better in the form of the Mobicat MC 110 EVO mobile jaw crusher, which has also been completely newly developed, and the further development of the Mobirex EVO series in the form of the MR 110 Z / MR 130 Z EVO 2.

Mobile MC 110 jaw crusher: Complete redesign

The plants of the new Mobicat EVO series have been redesigned from scratch, thus allowing the combination of new features such as the hopper walls integrated in the chassis or a fully hydraulic crushing gap adjustment with tried-and-tested concepts like the independent double-deck pre-screen (MC 110 Z), making the plants even more diverse and efficient. In addition to the "Z" version with active pre-screening, there will also be an "R" version, in which a slotted grate integrated in the vibrating feeder ensures pre-screening.

Crusher direct drive, electric auxiliary drives

As with the mobile impact crushers in the Mobirex EVO series, drive variants with direct drive crushers and electric drives for the extracting chute, belts and the pre-screen, are now used for the mobile jaw crushers. This means extremely efficient operation and allows optimal loading of the crusher. The so-called CFS (Continuous Feed System) controls an even more equal loading of the crushing area, in which the conveying frequencies of the vibrating feeder and the pre-screen are adapted independently of each other to the level of the crusher and thus help increase the performance significantly.

New crushing unit with hoisted crusher jaw

The new crusher impresses with its hoisted articulated crusher jaw, which on the one hand prevents the blocking of coarse material and on the other hand takes all fastening elements of the crusher jaw from the wear area. In addition, the transition from the pre-screen or the vibrating feeder is designed so that the material can simply tilt into the crushing jaw and convey an even material flow. With this property and other features, Kleemann achieves outputs of up to 300 tons per hour.

Mobirex EVO 2 mobile impact crushers: Even more efficient and versatile

After four successful years, Kleemann has consistently developed the Mobirex EVO series at a number of important points. The fundamentally already outstanding material flow which is characterized 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 successful impact crushers in the Mobirex EVO series have been consistently developed.

The optional oversize grain return conveyor has also been radically 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 expanded 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-center 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.

The highest levels of output and efficiency

The highly-efficient 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

Of course, 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".
