NPK Roller Extrusion Fertilizer Production Line Pulse Bag Filter Dust Collection Enclosed Conveying System
NPK Roller Extrusion Production Line with Integrated Dust Collection
This NPK Fertilizer Production Line features a comprehensive dust collection system designed specifically for dry roller extrusion granulation. Two-stage filtration with cyclone pre-separators and pulse-jet bag filters captures 99.5% of airborne dust particles, maintaining a clean workshop environment and full environmental compliance.
Dust Collection Features
Two-Stage Filtration: Cyclone separator captures coarse dust particles (above 10μm) as first stage, reducing bag filter load by 60-70%. Pulse-jet bag filter removes fine particles (below 5μm) with 99.5% collection efficiency
Enclosed Conveying System: All screw conveyors, bucket elevators, and belt conveyors are fully enclosed with dust extraction ports at every transfer point, preventing fugitive dust emission
Central Dust Collection Network: Piped collection system connects crusher, mixer, roller granulator, screener, and packaging stations to a centralized pulse-jet bag filter unit with automatic cleaning cycle
Dust Recycling: Collected fine powder is automatically returned to the raw material mixing stage, achieving near-zero material loss and improving overall production yield
Explosion-Proof Design: Anti-static filter bags, explosion relief panels, and grounding system for safe processing of combustible fertilizer dust per ATEX guidelines
Emission Compliance: Outlet dust concentration below 20mg/m³, meeting China GB 16297, EU Industrial Emissions Directive, and US EPA NESHAP standards
