Awarded: iF product design award for new Kleemann impact crusher Mobirex EVO 2
The new impact crushers Mobirex EVO 2 (MR 110 Z and MR 130 Z) were developed for crushing recycling material and natural stone. Thanks to new engine and drive technology, they work very efficiently and are very reliable and environment-friendly. In addition to the technical requirements, the engineers at Kleemann also considered other aspects such as user friendliness, ergonomics and environmental compatibility. They were extremely successful in the process, to the extent that the new crushers received the coveted "iF product design award 2014" for excellent product design.
The iF product design award is a globally recognised trademark for first-class design. Year after year manufacturers and designers submit their new developments to be assessed by an international jury. From a total of 3,249 submissions for the 2014 competition, the high-ranking jury praised the highlights. The new Mobirex EVO 2 plants from Kleemann are also among the prize-winners in the category "Transportation design / Special vehicles".
Many criteria are taken into consideration during the evaluation. The criteria include, for example, the design quality, the processing, the material selection, the degree of innovation, the environmental compatibility, the functionality, the ergonomics, the visualisation of intended use and safety.
Excellent ergonomics for operators and service technicians
The Kleemann developers implemented the ergonomic requirements in the design of the Mobirex EVO 2 impact crusher in excellent fashion: The functional groups and the material flow are clearly visible and easily accessible to the operator. At the same time, the clearly structured, transparent layout protects the drives and the operating technology where necessary.
The operation of the plants is very simple and logical thanks to a touch panel with straight-forward menus and clear visualisation. And there's another advantage: All components can be controlled from the ground.
The intelligent design also facilitates the work of service technicians, because the engine compartment, the crusher unit and the double-deck grizzly are easily accessible via convenient platforms with ladders for maintenance work. Even the concealed elements are easily accessible: The belt drive and the switch cabinets can be reached via cover openings, which are located separate from one another in the housing and thus protect the more sensitive components against vibrations and dust.
More productive and diverse
Kleemann also scored well in terms of functionality: Similar to the predecessor models, the material flow concept with its system widths opening in the material flow also impresses with the new plants, which are distinguished by the crusher inlet openings of 1100 mm (MR 110 Z) or 1300 mm (MR 130 Z). They enable feed capacities of up to 350 or 450 t/h. Unrestricted transfers of the system components and the new Continuous Feed System (CFS) also ensure smooth material transport: The system detects an overload by means of the various parameters and controls the material conveying speed accordingly. This control prevents a complete standstill of the feeder trough and grizzly, thus ensuring quick operational readiness of the system again after an overload has occurred. Another advantage is the familiar efficient operating principle of the independent double-deck grizzly. Here the lining replacement for both the upper and lower deck was simplified significantly.
The optional overgrain size return conveyor has also been redesigned. Thanks to the bend-free conveyor and the by-pass device 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. The plants are thus perfectly suited for contractor operation.
Simpler transport thanks to the hook lift system
With the new design of the overgrain size return conveyor, there is also greater ground clearance in the area of the optional screening unit. In this way, driving the plant with an attached screening unit onto a drop-centre loader is considerably easier. The screening unit also has a hook lift system, which enables simple, separate transport of the unit.
Save fuel and comply with strict emissions legislation
The economical use of resources is also rated by the jury of the iF design award. The new plants also impressed in this area, because its drive concept with a direct crusher drive via fluid coupling and electrically driven vibrating chutes, screens and conveyor belts is extremely efficient. This results in a significantly lower fuel-consumption ratio per ton of material. The forward-looking equipment is compatible with the plants, which are available either with engines in accordance with emissions level EU IIIA or EPA Tier 4f.
