The Ecostar screens for waste treatment plants are superior to trommel screens because they guarantee higher productivity, superior flexibility, better quality of the screened product and a reduction in investment and maintenance costs.
Every year we replace big trommel screens with Ecostar dynamic disc screens, guaranteeing the same production volume while halving footprint and power consumption. The compact size of the Ecostar dynamic disc screens, compared to that of huge traditional trommels, guarantees room saving. This means less investment costs (space, conveyors and steel structures). This makes Ecostar’s technology very cost-effective in terms of power consumption, saving up to 70% when compared to traditional screening systems. For example, in a waste treatment plant, one Ecostar screen (total length of 9 mt.) guarantees the same production volume than two trommel screens (total length of 25 meters).
Trommel screens, after a few hours of operation, become dirty and stuck, decreasing the screening performance and results. The Ecostar technology does not allow the material to twist around the shafts or to clog among them, thus facilitating its easy separation and considerably reducing downtime. Ecostar screens are open at the top and very fast and easy to clean. In most cases, the Ecostar screens can be cleaned by simply reversing the rotation of the shafts.
The efficiency of the dynamic disc screening technology permits the use of 7.5 kW electric motors up to 20 t/h. This makes this technology very cost-effective in terms of power consumption, saving up to 70% when compared to traditional screening systems.
