Globally, there has been a growing recognition of the importance of sustainable waste management and recycling, which translated into a higher demand for recycling technologies whether shredders or screeners to treat and recover much of the waste we produce. International agreements have been developed, objectives have been set, infrastructure investments have been made, producers are held responsible for the waste they produce, and recycling education campaigns to improve waste segregation and recycling practices have been unfolded. While the world has become more aware of recycling, the availability and adoption of recycling technologies still vary a lot across regions and countries. There are numerous recycling technologies available, however, their implementation and effectiveness can depend on various factors: from economic feasibility to available or needed infrastructure, to waste materials that differ in moisture, density, and mix from one region to another, that can pose technical challenges.

Our stationary disc screen, Hexact, has been proven to be a super adaptable and extremely effective solution to different waste and recycle materials, no matter the region, the material, or the operator’s available infrastructure. Here are some of the screener advantages and cases where the Hexact stationary screening machine has been working with great results.  

The waste screener is compact and needs little space which doesn’t compromise its productivity and effectiveness

In case you have not seen our stationary machine at work, you should know that it has been developed with a modular design, meaning that it starts from 2 meters and can reach 10 m in length by adding 2/3-meter modular sections. Its compactness solves a lot of the operators’ problems regarding the available space, and infrastructure whether the machine needs to work in a new or an already existing line. And when we say compactness, we mean that, apart from the modularity, the stationary screener is 1270 mm high, with a working width of 1600 mm and a total width of 2310mm so you can understand that it is super flexible, it reduces assembly times and transport costs, especially for large screening surfaces such as those of the Hexact 8000, 9000 and 10000 (3+2+2+3m).

A good example is the Hexact 8000 working with plastics in a plant in Italy whose line was already operational when the stationary disc screen was designed. As you may see, the screen perfectly fits the space where it treats 25 T/H of films and plastic at a section of 250mm. The machine is equipped with DDS (Dynamic Disc Screening) & SWAT (Screening Width Adjustment Technology) technologies – the DDS reduces the material to twist around the shafts while the SWAT is perfect for large materials and sections allowing operators to change the screening section on-site whenever necessary.

The on-site adjustable screening size system (±30%) is another feature given by our patented DDS technology that is greatly appreciated by our customers, where the original screening section (ex. 50mm) can be changed in real time with the help of the inverter. Moreover, equipped with 2 or three screening fractions the system becomes unbeatable, allowing operators to work multiple materials with the same machine. This specific feature can be of incomparable help to operators working with materials such as waste wood, organic waste, MSW, and RDF especially when the shredder is worn out or the material is wet. Here’s an example of waste wood, at an initial section of 80mm, that changes only by varying the speed of the shafts.

Quality of separation is every customer objective, and our forefront technology has been delivering the right results with multiple materials, whether it is waste wood, plastics, organic waste, or MSW which in many countries is still not separated at source. Here are some examples of plants where our stationary screen is currently working.

Waste wood and biomass with Hexact 8000 and Hexact 6000 in an MDF plant in Italy

The plant features 2 stationary screens – an Hexact 8000 that treats waste wood at 0-10mm and 40mm, while the Hexact 6000 treats biomass, at a 0-50mm fraction. The underscreen of the Hexact 8000 is being used for the production of MDF panels, while the overscreen ends up in a grinder. Both screens work around 60 T/H of material, cleans it from dirt and aggregates and calibrates it at the right size.

Old MSW recovered from landfill for the production of SRF

Here we are in a plant in Thailand where 6 Hexact screens (5000 and 3000) divided into 3 lines work in line a with a wind shifter and treat 40 T/H /line. The MSW is treated to obtain heat and power for cement production. Each line is made of an Hexact 5000 that works at a 40mm fraction, followed by a wind shifter, and a second Hexact, this time a 3000 that works at a 120mm fraction.

Hexact is an unbeatable screening system not only thanks to the DDS technology it is equipped with, but also to the quality of materials with which it is designed, which last over time, meaning low maintenance costs for the operator.
