Shandong Tonda’s gravity dewatering screen relies on inclined polyurethane panels to separate water from materials using natural gravity, requiring no external power except for material feed. The panels feature a stepped design with increasing slot sizes (1–5 mm) along the incline, allowing fine particles to settle while water drains through. The polyurethane’s low friction coefficient (0.3–0.5) facilitates smooth material flow, while its chemical resistance makes it suitable for acidic or saline environments. Commonly used in sand washing or wastewater pretreatment, this low-maintenance screen offers energy-efficient dewatering with minimal operational costs.
