The new Doppstadt HS 401 Selector is able to reliably sort out oversize material.
The HS 401 Selector separates oversize material to reach the quality specification required. The HS 401 combines with the DW 3060 Type F pre-shredder to form a compact and efficient shredding and screening system. This combination system is suited for various input materials. Depending on the requirement, the DW 3060 Type F shreds biomass and waste wood with 0 to 300 mm (0 to 11.8 in) grain size. After this, the HS 401 Selector separates the unwanted oversize material from the finished fraction. An integrated conveyor returns it to the pre-shredder to be shredded once again. This method eliminates oversize material from the process.
The advantage of the new pre-shredder is that the shredding roller, tooth bar, teeth and limiter elements can be exchanged individually according to the material requirements and the required grain size. Depending on the application there are four different tooth sizes available for the F series. The modular systems allow Doppstadt to offer flexible solutions that meet the customers' requirements. All the machines can be modified and combined. According to the required result, the different parts of the machines can be exchanged, or complete machines can be combined to form new, interconnected processing lines.
