Unique in its kind, it uses a series of shafts with hexagonal or octagonal flat discs made of Hardox steel to ensure maximum wear and abrasion resistance. Thanks to this special shape, the material flows over the screening discs and is subjected to up-and-down vibrations that separate the waste components. The screened material falls through the screening plane, that is, through the spaces between the discs; the material that remains on the discs is conveyed to the end of the screening plane itself. The result is a separate and clean fraction, ready for the respective recycling processes.
DDS allows real time changes to the predetermined screening section (± 30%), which can be obtained by varying the speed of the shafts with the help of the inverter. The available screening sections range from 10 to 350 mm. The DDS technology enables our machines to separate materials faster (1 m/sec), using less space and reaching a productivity level of up to 200 t/h.
The traction shaft is covered with loose sleeves made of highly resistant material, which are independent of the rotation of the shaft itself to prevent the long and fibrous parts of the material to be screened from getting twisted on the shaft. This is critical for optimal screening results and for considerably reducing downtime.
The efficiency of the technology based on disc screens results in a spike in productivity as well as in the revenue from the sale of recycled materials. At the same time, it guarantees low maintenance costs, more efficient use of space and accessory structures, and a reduction in energy consumption.
