How Briquetting Presses Reduce Dust Pollution in Production

Dust generation during briquetting can pose health, safety, and environmental risks. Modern briquetting presses incorporate multiple strategies to minimize airborne particles while maintaining efficiency. Here’s how they control dust pollution:

1. Enclosed System Design

• Sealed Feeding Hoppers: Prevent dust escape during material input.

• Closed Conveyor Belts: Transport raw materials without exposure to open air.

• Dust-Tight Compression Chamber: Contains fine particles during pressing.

2. Dedicated Dust Extraction Systems

• Cyclone Separators: Centrifugal force captures airborne dust before venting.

• Baghouse Filters: High-efficiency fabric filters trap fine particles (up to 99%).

• Wet Scrubbers: Water sprays neutralize dust in coal/metallic briquetting.

3. Material Conditioning

• Moisture Control: Maintains 8–12% moisture in biomass to suppress dust.

• Pre-Agglomeration: Roller compactors or binders (e.g., starch) reduce fines before pressing.

4. Process Optimization

• Reduced Drop Heights: Minimize particle dispersion during transfers.

• Vibration Damping: Lowers material agitation and dust release.

• Automated Cleaning: Built-in air jets or brushes remove residual dust from dies.

5. Worker & Environmental Protections

• Local Exhaust Ventilation (LEV): Directs dust away from operators.

• PPE Support: Presses in dusty environments include integrated respirator hookups.

• Noise-Enclosed Cabinets: Some designs combine dust and sound insulation.
