The new hook-lift separator HS 800 Selector combined with the shredder DW 3060 Type F was showcased on the exhibition ground between hall C1 and C2. This system and another innovation, the rear star screen HS 514 Selector, combined with the crawler track mobile shredder DW 3060 Type F combines two recycling procedures: The system shreds waste wood, green waste and sorted wood and plastic waste and afterwards screens them to the required grain size. The input material is shredded without being pulverized. The undesirable fine fraction in the final product is reduced to a minimum. The rear star screen works without any separate drive and leads the oversize back to the shredding unit by means of a return conveyor, so that the material will precisely meet the specifications. Thanks to this procedure optimizing the product in a recirculating flow, a high-quality product with homogeneous grain size is achieved. The crawler track mobile system can be used flexibly at various locations.
At Ifat, Doppstadt showcased another separating solution – the splitting. This method enables up to three fractions to be separated depending on the material properties without plugging and wrapping. A Splitter loosens, separates and doses various materials. A pre-treatment is only required in certain circumstances. Mixed construction waste can be treated as well as stones and soil, metal scrap, slag and landfill residues. The world first Splitter H2 System, offers extraordinary flexibility: Thanks to the modular construction, the machines can be composed individually – to meet any requirements.
For the first time, Doppstadt exhibited the screen SM 720 Plus. The new model of the Doppstadt series of screens is the biggest: 40 per cent more hopper volume, 20 per cent more discharge heap volume at the rear and side conveyors and German state-of-the-art engine technology – but for all that the machine mounted on a semitrailer chassis ensures road traffic mobility.
Furthermore, the mobile large-scale chipper DH 910 SA with a swiveling rear conveyor instead of the discharge chute was showcased. The chipped material is not thrown through the air, but transported and discharged by a rear conveyor with 60-90 ° swiveling range thus reducing the fine fraction to a minimum and increasing the throughput capacity. Log timber up to 900 mm is reduced to wood chips with a precisely defined chip size.
