SCREEN
Core Components
A Key Step in Mix Quality
Advantages
Precise multi-fraction aggregate separation. Ammann vibrating screens separate heated aggregate into multiple size fractions, typically across 4 to 6 decks, for accurate hot bin storage and recipe-level grading control.
High-temperature structural integrity. Screen deck frames and drive systems are designed for continuous operation with hot aggregate at temperatures up to 200°C, preventing thermal distortion that would reduce separation accuracy over time.
Individually exchangeable screen mesh panels. Mesh sections can be replaced individually when worn or when aggregate grading requirements change, limiting downtime to the specific deck section that needs attention.
Heavy-duty eccentric shaft drive. Consistent vibration frequency and amplitude are maintained across the full screen width, delivering reliable separation efficiency at peak throughput without uneven wear across the deck.
Oversized material overflow management. Overflow chutes handle aggregate fractions that exceed hot bin specification, preventing contamination of correctly graded hot bin fractions from oversized carry-over material.
Low dust emission screen housing. Sealed screen housings with exhaust gas return connections minimise dust escape during hot aggregate separation, protecting the working environment around the plant.
as1 integration for screen monitoring. Screen drive status and overflow conditions are monitored in real time via the as1 control system, alerting operators to screening issues before mix quality is affected.
Capacity-matched to plant throughput. Ammann vibrating screens are specified to match the throughput of each plant configuration, ensuring the screening stage is never a production bottleneck.
