Eco-Star® vs Tommel Screen: Capacity and Footprint
Every year, Eco-Star® replaces long trommel screens, providing greater production capacity in a smaller footprint. Screening in a trommel is only accomplished on the bottom of a drum. With any given trommel diameter and length, the screen area of the machine is defined by 1/3 of the drum diameter by the screen length.
As compared to a given length of screen area, a trommel only provides 1/3 of the effective screen area as a comparable rectangular design of the Eco-Star®. In addition, the trommels installation height due to its diameter and angle of inclination, provide constraints to installation of sufficient screen area. The Eco-star®’s low profile design is usually installed with no or little inclination. This feature added to the large effective screen area of the screen provides substantial capacity advantages in a given footprint.
Cleaning and Maintenance
Another factor greatly effecting screen capacity is the cleaning and maintenance of the screen. If the openings in a screen are not open and clear, the capacity of the screen is greatly reduced, resulting in fines carry over or reduced system capacity. With the Eco-Star®’s patented ant-clogging system, the screen remains free and clear, resulting in continuous high capacity efficient screening with less down time. The reliability of the Eco-Star® screen and lack of time required for cleaning means more operation time and more production volume through your system.
Compact Size and Flexibility
The compact size of the Eco-Star® Dynamic Disc screen compared to the dimension of a trommel sized for a given application provides significant space savings and a compact footprint.
Eco-Star® screens can be arranged with multiple cut sizes in a single deck or units with different separation sizes can be stacked on top of each other. A cascade arrangement with several screens can also be configured in a small foot print. The ability to arrange your shredder and screen in a compact footprint as pictured, provides significant cost savings during construction in reduced structure, conveyor and building requirements.
Arranging the Eco-Star® with recirculation to your shredder reduces wear and maintenance costs on the most expensive piece of equipment in your operation producing a high quality uniform product.
