The Ecostar waste separator are superior to the star screens in terms of performance, efficiency and adaptability to screen every type of product. The duration of the Ecostar dynamic disc screens is also higher, since the star screens do not maintain a proper section over time.
Star screens can only work with compost and wood (no waste). Ecostar separators are designed to separate every kind of material: MSW, RDF, C&D, ash, wood, tires, compost, organic waste, biomass, PET, car fluff, demolition waste.
Rubber stars are weak and do not have a reliable section over time, therefore the screening section precision is reduced in the long run. Ecostar Dynamic discs are in Hardox. In star screens the whole set of stars must be changed 1 or 2 times every year, due to the fragility of the rubber stars. Since Ecostar discs are made of Hardox, which is an extremely resistant material, it is sufficient to replace the first 4-6 shafts once a year.
In star screens, the screening deck needs to be inclined upwards in order to operate efficiently. The Ecostar Dynamic Disc Screen works in flat or downhill position thanks to the hexagonal discs that shake the material very well. Furthermore, in order to obtain a high-quality separated fraction, star screens must move upwards, which affects the production volume.
