Wirtgen Mineral Technology Days 2015 attracted more than 2,500 trade visitors from over 100 countries.

Benninghoven GmbH & Co. KG hosted the Wirtgen Group?s eighth international industry get-together in 2015. More than 2,500 trade visitors from over 100 countries were treated to a demonstration of practically oriented and pioneering solutions from the Wirtgen Group mineral technologies business sector at the home of the asphalt mixing plant specialists in M?lheim an der Mosel.

Steel giants in action
The applications experts at the Wirtgen Group staged live demonstrations of how things can actually work in practice. The two surface miners 2200 SM 3.8 and 2500 SM are representative of the wide range of applications for which the Wirtgen machines are used in the productive extraction of soft to hard stone. The 111-t Wirtgen surface miner 2500 SM operated at 1,065 hp when mining material and loading it directly onto trucks via a conveyor belt. Kleemann was notable not only for its interlinked machine combination consisting of the jaw crusher MC 110 Z EVO, the cone crusher MCO 9 EVO and the screening unit MS 16 D for crushing natural stone in various high-quality final grain sizes in a three-stage process chain. Once the mobile impact crusher MR 130 ZS EVO 2 had clearly demonstrated how even large quantities of natural stone can be processed, the Kleemann jaw crusher MC 110 Z EVO showed how both machines can also deal effortlessly with high-performance concrete and construction waste recycling.

Host of the event, Benninghoven, hit the mark with its granulator MBRG 2000-2 and the gentle granulation of RAP with subsequent separation into two fractions. The operation and control of the asphalt mixing plant TBA 3000 was demonstrated on site, covering the material flow from the cold feed stage through the drying and heating processes to the actual mixing process and subsequent loading of the finished mixture.

Innovative products
Wirtgen: Wirtgen showcased a new cutting drum unit for the flagship surface miner 4200 SM that was specially designed for the windrowing method. Delivering a 15 per cent increase in output and a 15 per cent reduction in tool consumption compared with the standard cutting drum unit, this innovation is set to maximise the cost-efficiency of mineral deposit extraction.

Kleemann: The MOBICONE MCO 9 EVO was the centerpiece of the Kleemann exhibits. This track-mounted mobile cone crusher fills one of the last remaining gaps in the Kleemann range of models. Like the other Kleemann crushers in the EVO series, the MCO 9 was specially developed to meet the needs of customers in the contractor market and owes its appeal to its user-friendly operation and easy transport, in addition to optimum interlinking options. The live demonstration clearly illustrated what a perfect match the MCO 9 EVO is for the mobile jaw crusher MOBICAT MC 110 EVO. Teamed with the mobile triple-deck screening unit MS 16 D, the machines formed a very productive interlinked machine combination for processing natural stone.

Benninghoven: The majority of the products on display in Mnlheim were contributed by the asphalt mixing plant specialist, Benninghoven, which presented as many as 14 exhibits. The new hot gas generator was a particularly big attraction. The indirect heating of RAP in counter flow using a hot gas generator is a particularly environmentally friendly and efficient technique that Benninghoven has been applying and continually advancing for decades.

Complete process chain
With Benninghoven coming into its fold, the Wirtgen Group now offers a complete range of solutions in the mineral technologies business sector for the extraction of mineral deposits, the processing of mineral raw materials and recycling materials and the production of asphalt.
