Asphalt plant design: types, efficiency and fuel-saving choices

Batch vs. continuous: Process and throughput

Batch asphalt plants

• Exact recipe control - the as1 Control System maintains tolerances, enabling rapid changeovers.

• Multiple specifications per shift - ideal for urban roads, airports, and specialty applications.

• Proven quality - hot bins, weigh hoppers, and pugmill mixing deliver reliable performance that meets international standards.

Continuous asphalt plants

• Uninterrupted material flow - integrated drying and mixing deliver high throughputs with cost-efficient design.

• Fuel-saving operation - steady burner load reduces energy consumption. Ammann burners optimize efficiency across multiple fuel types.

• Simplified layout - fewer moving parts reduce maintenance needs and spare-part requirements.

Mobile vs. stationary: Set-up, footprint, permits

Mobile & modular plants

• Rapid installation thanks to pre-assembled modules, with minimal foundation requirements.

• Ideal for temporary projects or contractors that relocate seasonally.

• Compact footprint often supports streamlined environmental approvals.

Stationary plants

• Robust steel structures with larger silos and towers built for long-term, high-volume output.

• Commissioning typically requires additional time for civil works and utility integration.

• Well-suited for integration with depots, laboratories, and logistics hubs in metropolitan supply chains.

Which design saves the most fuel per tonne?

• Ammann counterflow dryers: Maximize heat transfer, delivering up to 20% fuel savings compared to all traditional designs.

• Ammann ADX Drying Expert: Real-time temperature monitoring reduces fuel by up to 7% while extending component life.

• Warm Mix Asphalt (WMA): With Ammann Foam technology, production temperatures are lowered to 110-135°C (vs 150-180°C for hot mix), cutting energy use and emissions.

• Fuel-flexible burners: Ammann burners operate on hydrogen, natural gas, bio-oil, wood dust and many other fuels, enabling carbon reduction strategies without compromising performance.
