DRYERS
Core Components
Maximising Plant Performance
Advantages
Counterflow drum design. Aggregate and combustion gases travel in opposing directions, maximising heat transfer and reducing fuel consumption compared to parallel-flow drum alternatives.
Consistent moisture removal. Aggregate drying performance remains stable across varying cold feed moisture content, maintaining production output quality throughout changing weather conditions.
Wear-resistant internal flights and lifters. High-chrome and hardened steel internals extend dryer service life and maintain consistent aggregate curtain density for uniform heat exposure across the drum.
RAP-compatible design. Ammann drum dryers are configured for RAP (Reclaimed Asphalt Pavement) feed integration, supporting sustainable mix production with recycled material.
Precise temperature control via as1. Integrated thermocouple monitoring and as1 control system integration maintain aggregate exit temperature within specification, protecting mix quality and preventing binder ageing.
Reduced fuel consumption per tonne. Counterflow efficiency and optimised drum internals lower energy cost per tonne of mix produced, compared to older parallel-flow drum designs operating on the same feedstock.
Long service life with extended maintenance intervals. Ammann drum dryers are designed for extended operation between planned maintenance shutdowns, reducing scheduled downtime cost over the plant's operational life.
Global support and spare parts availability. Drum internals, drive components, and sealing systems are available through Ammann's international service network for rapid supply to minimise unplanned downtime.
