HEXTRA
Thanks to DDS (Dynamic Disc Screening) technology, Hextra is able to screen materials faster (1 m/sec), using less space and reaching a productivity level of up to 200 t/h. Revenue from the sale of recycled materials can be increased thanks to the unique characteristics of this system. The top quality of its components and assembly procedures, far superior than market standards, guarantees maximum reliability and a reduction in maintenance costs.
Thanks to SMART HOPPER – the special loading hopper developed by Ecostar – Hextra is in fact, a screening system with unbeatable flexibility. Its sliding hopper is equipped with a dosing screw which also enables it to operate in a loop with all shredders.
Its hydraulic system, operated from the control console, enables the screening options to be changed from 2 fractions to 3 fractions in relation to specific processing needs. The hopper slides to reduce its dimensions to a minimum during transport.
Hextra is available in tracked and roll-off versions, with 2 and 3 screening fractions and screening surfaces from 5 to 7 meters in length.

Industries & Applications
NHEXA 5000 2F / 3F
Nhexa is the compact, flexible, and efficient screening solution, ideal for treating low to medium waste and recyclable materials. A machine that combines maximum operational efficiency with the precision of the innovative patented Dynamic Disc Screening technology.
PRODUCTIVITY FROM 10 UP TO 50 T/H
Nhexa is capable of screening all types of materials, using minimal space and achieving a productivity level of up to 50 T/H. With a screening surface of 5 meters in length, Nhexa can be configured with 2 or 3 screening fractions and with sections ranging from 20 to 100 mm.
MAXIMUM ADAPTABILITY
Thanks to the flexible configuration of the discharge conveyors, Nhexa easily adapts to any operational context. Depending on the configuration of the site and operators’ needs, the conveyors for the fine and medium fractions can be positioned on the same side or on opposite sides, ensuring efficient space management and optimized material flow.
LEAN LOGISTICS
Nhexa’s compact design and tracked configuration ensure high mobility, allowing it to be positioned even on challenging terrain or in landfills. Its optimized dimensions enable transportation in 40’ high cube shipping containers, drastically reducing logistics costs compared to the Flat Rack containers required for other screening unit versions.
OPERATIONAL EFFICIENCY
Designed to deliver high performance with quick and efficient maintenance, Nhexa features a modular screening surface that allows for fast section and shafts replacement, significantly reducing intervention time. Moreover, the automated opening side covers provide easy access to the screening deck and main components, simplifying cleaning and maintenance operations and minimizing machine downtime.
Ecostar Technology
DDS: Dynamic Disc Screening
Unique in its kind, DDS is based on a series of shafts equipped with hexagonal or octagonal discs, with a flat profile, made of Hardox to guarantee maximum resistance. Thanks to this design, the material flows on the screen’s discs and is subjected to a jolting movement that separates the waste. The undersized material drops below the screening surface, passing through the gaps between the discs while the oversized material advances to the end of the screening plane. The result is a clean fraction, ready for recycling processing.
Anti Wrapping systems: The drive shaft is protected by highly resistant loose sleeves which are independent of the rotation of the shaft itself. This prevents long and stringy parts of the material being screened from getting wrapped around the shaft. This optimizes the separation and significantly reduces downtime.
HDDS: Hyper Dynamic Disc Screening
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.
Anti Wrapping & 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.
SWAT: Screening Width Adjustment Technology
SWAT discs consist of two semicircles with a double spiral which are mounted in series directly on the drive shaft between the hexagonal discs. Depending on the positioning of the SWAT discs, it is possible to configure different screening sections, ranging from 150 mm to 200 mm or from 200 mm to 100 mm, in just a few minutes. The installation can be carried out on site on operational DDS screens with screening sections starting at 100 mm and above.
The double spiral shape pushes large materials upward, separating the oversize from the undersize more efficiently. In addition, the risk of material wrapping around the shaft is minimized and the quality of the separation is increased.
