Recycling GmbH Lahnau processes natural stone and rubble, including large volumes of concrete and the new MC 110(i) EVO2, which has been operating at the quarry since March, is to be used in both areas.
"What impressed us most with the new machine were the crusher jaws that open automatically in case of overload," said Ralph Lang, technical manager of Recycling GmbH Lahnau, adding that the overload system increases the output and productivity.
In case of short-term overloading at selected points, the new overload system of the MC 110(i) EVO2 automatically opens the crusher jaws already after 2 seconds, which is significantly faster than previous crushing equipment used at the quarry. The system then positions the gap back to the previously set values. Damage to the crusher is thus effectively avoided, which also means that the crusher produces aggregate in a constant quality.
"We will use this crusher in natural stone and in rubble recycling," says Daniel Weis, who is responsible for mobile processing and recycling plants at Recycling GmbH Lahnau. "Thanks to this function, large single parts do not usually cause any damage."
Kleemann says that the crusher also offers reduced noise emissions due to a new ventilation concept independent of the output. The EU Stage V engine in combination with the direct drive is desiged to guarantees a comparatively low noise development.
"Noise protection has become extremely important," says Lang. "In urban areas, on account of noise emissions now and then we only receive an operating permit for two hours a day. Quieter machines can be operated for longer periods accordingly, which also increases the daily output. In short: the excellent key data of the MC 110(i) EVO2 with regard to noise helps us with the operating permit."
The crusher also features integrated cameras with one monitoring the feed hopper and another the crusher. The image can be viewed at the operator panel and is also transferred via wireless LAN (WLAN) to an external camera, which can be positioned, for example, in the excavator. Kleemann says this view of the interior of the crusher makes operation easier and material processing safer.
