Rotary Calciners for Advanced Fly Ash Beneficiation
Rotary Calciners from Heyl Patterson Thermal Processing are engineered to deliver the controlled, high-temperature environment required for effective fly ash beneficiation. By targeting unburned carbon and chemically bound compounds, these systems enable producers to upgrade ash quality and meet stringent specifications for cementitious use.
- Reduce Loss on Ignition (LOI) to meet ASTM C618 requirements
- Deliver uniform temperature profiles for consistent processing
- Optimize residence time control for varying ash characteristics
- Support sustainable beneficiation strategies and landfill diversion
Solve Problems Before They Reach the Mixer
Rotary dryers from Heyl Patterson Thermal Processing are built to handle the variability and moisture challenges associated with coal ash, including ponded and landfill-recovered materials. These systems provide efficient, reliable drying to improve flowability and ensure material is ready for beneficiation or direct reuse.
Common challenges we help to solve:
- Reduce moisture content for improved handling and transport
- Enhance flowability and minimize material buildup or plugging
- Improve feed consistency for downstream beneficiation systems
- Designed for abrasive, variable feedstocks common in CCPs
- Enable processing of ponded ash and reclaimed materials
