HDDS, screening technology for complex materials

HYPER DYNAMIC DISC SCREENING

Hyper DDS (Dynamic Disc Screening), is the new screening system developed by Ecostar, capable of accelerating and improving the separation process of difficult materials.

HDDS, screening technology for complex materials

The solution for screening difficult materials

HDDS is the Ecostar technology for the separation of particularly difficult waste containing long and stringy materials, such as bags and plastic straps used for packaging, which can wrap around the shafts, or plastic bottles that can get stuck during the screening process.

Hyper DDS: anti-wrapping and anti-clogging

Thanks to its special flap, Hyper DDS technology is able to hook bags or stringy materials that could become wrapped around the screening shafts by pushing them forward and keeping them over the screening surface. Its jolting movement enables the optimization of the separation process of materials such as plastic bottles and cans, so as to obtain a superior quality of the screened fractions for their subsequent processing.
