Sweep Auger for Cone Bottom Silo
The sweep auger for cone bottom silo is designed to assist discharge in hopper (cone-bottom) silos where gravity flow alone cannot completely remove stored material. By combining auger conveying capacity with natural self-flow, the system ensures efficient clean-out while maintaining stable and controlled operation.

Industry Pain Points & Hongrui Solutions
Traditional cone bottom silos often suffer from several critical operational issues that our sweep auger is specifically designed to solve:
- Severe Material Bridging: Materials like Brazilian soybeans are highly prone to hardening and wall-clinging, making spontaneous flow nearly impossible.
- High-Risk Manual Operations: The steep angles of cone bottoms and lack of safety clearance make manual labor inside the silo extremely dangerous, often leading to safety accidents.
- Low Discharge Efficiency: Without specialized equipment, the structural limitations of hopper bottoms result in sluggish output and incomplete clearing.
- Space & Structural Constraints: Internal ventilation ducts and limited sub-silo space often prevent the installation of standard cleaning tools.
Hongrui sweep auger for cone bottom silo addresses these by providing a fully automated, unmanned operation that fills the market gap for customized cone bottom discharge.
