mobile crushing and screening processes. Powered by a low-emission 310 kW Cat C13 diesel engine and weighing 58t, the LT110C is 15.6m long, 3m wide and 3.85 m high when being transported. Optional accessories include wireless remote control, a dust-control system, a hydraulic hammer to clear feed blockages and generator.
Kleemann Kleemann, a member company of the Wirtgen Group, has developed two completely new Mobirex mobile impact crushers that are also suitable for recycling applications. “To attain genuinely better performance, we were not satisfied with just addressing individual components,” says Thomas Kühnle, Head of Technology at Kleemann. “The key to a real increase in performance was the redesign of the flow of material encompassing all components.” The new material flow concept consistently prevents narrowing of the material stream, and the system widths of the conveyor elements “open” in the material flow direction. This allows performance values to be attained that are unmatched in these size classes. The smaller of the two machines, which has a crusher inlet opening of 1100 mm, can handle input capacities of more than 350 t/h. The larger system, which has an inlet opening of 1300 mm, can attain input capacities of 450 t/h and higher. Both machines are equipped with direct drive. A latest-generation diesel engine transmits its power almost loss-free via a robust fluid coupling and V-belts directly to the flywheel of the crusher. This drive concept also enables enormous versatility, as the rotor speed can be adjusted in four stages. As a result, the machines are equally well-suited for use in quarries and in recycling. The most important new feature of machines is the completely new impact crushers of the SHB series. They feature many convincing new detailed solutions that are unmatched, from the hydraulically actuated crusher inlet

in extremely robust heavy-duty cast design to the optimised, steeper inlet angle, to the new blow bar fastening system. All have a positive effect on availability. In addition, the SHB crushers have an innovative fully hydraulic crushing gap adjustment that can be quickly and easily operated from the operating panel.
DSB Innocrush Although German crusher manufacturer DSB Innocrush is not launching any new products this year, the company is proud to present the results of its pioneering trials in crushing and recycling a special asphalt used in Finland. DBS has been working closely with its Finnish partner KH Koneet OY, which has supplied an Innocrush 50 and an Innoscreen 25 to one of its customers for use in the trials. Previously, temperature conditions in Finland have only permitted crushing with a jaw crusher during winter months. DSB has now set new standards by crushing and processing asphalt in an impact mill over the entire year. The wear costs are somewhat higher for an impact mill, but the possibility of crushing over the entire year, combined with the production of perfectly finished material, mean a much higher profit. Thanks to the unique crusher geometry, the Innocrush 50 with its 1.3 m diameter rotor, the largest impact mill in the current range, guarantees extremely high capacity. During the trials, 270 t/h of asphalt was processed with a feed size up to one metre. The downstream double deck screen separates the material into the required fractions of 0-11 mm, 11-16 mm and 16-80 mm.
Keestrack + Omtrack In March, Belgian manufacturer of track mobile screening plants Keestrack N.V. acquired a major share of Omtrack s.r.l., an Italian manufacturer of track mobile crushers. Both companies see their market position strengthened through the combination of their advanced product lines. “We are adding the well established and proven mobile crusher line of Omtrack to our product line of track mobile screeners,” says Klaus Elit, area sales manager at Keestrack. “The new, more complete product line allows a further expansion of the already existing dealer and distributor network for both companies.”
