Next-generation crushers from Kleemann

Earlier in the year, Kleemann showcased the Mobicat MC 100 R mobile jaw crusher and MR 110 ZS mobile impact crusher (from the Mobirex Evo series). Characterized by its compact and extremely robust design, the 36-tonne MC 100 R is suitable for smaller jobs and can be hydraulically lowered to a height of 3,200mm for transport purposes. The crusher is powered by a 228kW engine which, together with the hydraulic crusher drive, ensures maximum feed capacity of up to 200 tonnes/h. 

In the event of blockages in the crushing jaw, the reversible crusher drive helps the machine to move again freely without any additional auxiliary means. The infinitely variable gap setting proves particularly useful for frequently changing material, as the plant can be adapted to new specifications in minimal time. The MC 100 R can thus be used more flexibly for stone or diverse recycling applications.

Since their market introduction two years ago, the Evo plants have demonstrated a sophisticated material flow concept, which enlarges the system widths in the direction of the material flow to ensure enhanced performance, less wear and optimum values in terms of consumption per tonne of broken material. 

The MR 110 ZS Evo not only boasts a Kleemann stand-alone double-deck grizzly screen but also has high-performance electromagnets. The screening unit incorporates an oversize return conveyor with a 40% larger screen surface in comparison to the previous model.

Flexibility played a key design role in the development of the Evo series plants. This began with the new feeding unit and fully automatic hopper locking mechanism. Then came the new touch-panel control system with status displays in clear text format, followed by the completely redeveloped crusher. 

In addition, the infeed geometry has been redefined for better penetration of the material in the impact range of the rotor. The new C-Shape rotor ledges remain sharper for longer and are characterized by a clamping system which makes changeovers much easier. 

A major feature of the impact crusher is the fully hydraulic and automatic gap setting, which permits the crusher gap to be adjusted to  millimetre precision using the touch panel when the rotor is running.

According to Kleemann, this increases the quality of the final grain and availability of the plant. The new overload protection system also contributes to the increased availability.
