Heavy-duty debris screening and crushing system engineered for ultra-high water flow and complex solid waste challenges in large municipal applications.
Product Overview
The FS Series Dual Drum Grinding Grille features innovative coiled or drilled drums positioned on both sides of the central cutting core, enhanced by dedicated diversion and overflow baffles. This dual-drum architecture ensures exceptionally stable head loss across large channels, precisely channeling wastewater debris directly into the grinding zone. Equipped with robust bi-directional cutting blades and utilizing low-speed, dual-shaft differential technology, it aggressively tears and crushes massive pieces of wood, plastics, and flexible textiles underwater.

Large Municipal Intakes & Diversion Canals: Massive flow area with dual drums and strategic diversion baffles makes this model ideal for wide, high-volume diversion canal inlets and water intake projects. Aggressively intercepts and pulverizes high-density floating debris while ensuring absolute stability in system head loss.
Underground Ecological Pump Stations: Perfect for modern pumping stations in urban centers or premium communities. Supports fully underground installations where shredded debris is carried away directly by sewage, eliminating manual retrieval. Allows pump station roofs to be fully landscaped while containing odors and preventing insect infestations.
Frequently Asked Questions
How do the "bi-directional cutting blades" and "dual drum structure" help in processing complex waste?
High-flow channels often contain a chaotic mix of flexible fabrics and hard debris. The FS grille utilizes ultra-destructive bi-directional cutting blades powered by a low-speed, dual-shaft differential mechanism, which aggressively tears and crushes waste to fundamentally prevent entanglement. The dual drums on either side (customizable as coiled or drilled) work in tandem with the diversion baffles to forcibly guide all solids directly into the crushing chamber, guaranteeing zero bypass.
Is the daily maintenance of this equipment complicated or expensive?
Maintenance is highly simplified. The equipment features an optimized transmission structure that makes the replacement of vulnerable parts—such as cutting blades—exceptionally easy, significantly reducing long-term maintenance labor and costs. Furthermore, to adapt to varying operational demands, the system can be configured with single or multiple motors, including IP68 fully submersible options, providing massive reliability and redundancy for long-term underwater operation.
