Description
Rotoflow bin agitators, silo dischargers or silo discharge aids, make the controlled flow of most non-free flowing materials possible in silos and prevent ratholing, bridging and incomplete material withdrawal from the silos.
The ABC Hansen Rotoflow 1400 has an inner diameter of 1400m – and is suitable for hopper bins with over 50m³ capacity – and will require a flanged connection to the hopper structure – and some adjustments on the hopper structure of the silo. The Rotoflow is installed outside the silo, due to the ease of installation – and the vibration is achieved using a high frequency vibration motor – which are recommended for dry, cohesive products that have a tendency to arch and bridge.
The rotoflow should be installed – so that it is only in operation, when the silo’s unloading conveyor is running – and you actually want to discharge the silo. Typically the Rotoflow and the discharging conveyor would be interlocked to run together. Running the Rotoflow – without discharging the material – may cause additional compaction of the material in the silo – causing more severe flow problem.
The vibration from the rotoflow is isolated from the silo structure – using high quality plastic/rubber mountings – between the silo structure and the bin discharger, ensuring that the lifespan on the hopper bin isn’t unduly influenced.
Flow rates on the 1400mm unit are up to 100TPH based on product with a density of 650kg/m³
Applications for the installation of rotoflow discharge aids include:
– Maize bran silos
– Wheat bran silos
– Semolina silos
– Animal feed silos
– Wheat flour silos
– And many other difficultly flowing material silos.
Advantages of the rotoflow bin discharge are:
- Low energy requirement
- Low maintenance requirement
- Durable construction with few moving parts
- Accessibility of unit and working parts
- Quick and easy installation
- Reduced wear on silos compared to other agitation methods
- No compressed air requirement
