Recycling boom in Denmark: Machine sets from Kleemann are boosting productivity in recycling jobs
The Danish recycling market has been experiencing a real boom over recent years. With the services they offer, MIS Recycling A/S are reaping the benefits of this trend: the company has already been actively involved in the processing of residual construction materials for the last 20 years.
To meet the huge demand, MIS now operate 10 impact crushing plants from Kleemann’s advanced MOBIREX series that achieve a high level of productivity.
In Denmark, MIS are playing a pioneering role with their services. Each year, the recycling company processes approx. 3 million tonnes of residual construction materials and 100,000 tonnes of natural stone. One of the most frequent applications is the processing of asphalt. The impact crushing plants crush RAP into grain sizes of 0–6mm and 0–20mm. The final product is returned to the asphalt production cycle. Occasionally bricks, concrete and track ballast are also processed. The crushing and screening plants are transported straight to the desired location, remaining on site for one to two weeks, depending on the size of the project. It is important that the machines deployed have a long service life and high capacity, which is why MIS have been relying on Kleemann for their screening and crushing plants for many years.
“The high quality and robustness of the plants impressed us as soon as we started using our first MOBIREX 130 mobile crushing plant in 2002,” says Martin Henriksen, Director of MIS Recycling A/S. In 2009 MIS decided to buy the latest MR EVO models. MIS now have 10 MOBIREX MR EVO2 plants and 3 MOBISCREEN screening plants of types MS 12 Z, MS 15 Z and MS 16 D. “The Kleemann plants just last longer, are more powerful and deliver a higher quality than other crushing plants we worked with,” says Henrik Hvid, Production Manager at MIS. “Service for the plants is also important for us. We can always rely on the team from the Wirtgen Group in Denmark.”
The continuous use of the MOBIREX EVO2 impact crushing plants creates synergies: since the MIS operating personnel are very familiar with the plants, they do not need to adjust to different technology from one project to the next. It also simplifies the storage of spare parts. What is more, the two latest MR 130 Zi EVO2 plants are equipped with the new SPECTIVE control system, which is particularly intuitive to use and even automates some machine functions. “It’s much easier to use the plants and no explanations are required,” says Martin Henriksen. “Our operators can control all machine functions and components very simply from the ground using the touch panel.” The flexibility of the plants is crucial for the contractor business. The MOBIREX EVO2 plants with their hydraulically folding hopper walls and side discharge conveyors are ready for operation in just 30 minutes.
MIS not only work with the latest technology, but also set great store by efficient processes. That is why the company has, for instance, developed its own app to facilitate the recording of operations on sites throughout the country. "It’s important for us always to stay one step ahead – whether in terms of the crushing plants or our project management,” says Henrik Hvid. “The benefit of our many years of cooperation with Kleemann is that we can propose ideas for options that could make our work even more efficient.”
The next few years are expected to see stricter regulations on the use of screening and crushing plants being implemented in the city centres of Copenhagen, Arhus and Odense. As it geared up for this development, it was important to MIS that the two new MR 130 Zi EVO2 plants met the exhaust emissions standard Tier 4 final. The Scania engine of the plant is fitted with a diesel particulate filter and a carbamide tank in order to reduce emissions of nitrogen oxides, carbon monoxides and fine dust. The company is thus well equipped to meet the future requirements of the Danish recycling market.
