CHALLENGES OF FLUIDCON
1.
Application of all known feeding devices
→ Optimization of existing plants
2. Horizontal, vertical and diagonal conveying sections
→ Optimumpipeline routing
3. Energy savings of up to 75%
→ Operationalcosts saving
4. Low conveying velocities
→ Reduction of wear
→ Constant materialproperties (low attrition)
5.
A Langley Holdings Company
Low conveying pressures
→ Use of blowers instead of compressor
→ Use of pumps,star feeders, double pendulum flaps
→ Low construction heights, low investment cost
6. Simplerestart after e.g. emergency stop
→ High availability

Target
• Prevent Air Current Segregation
• Maximizing Silo Capacity
• Maximizing Homogenization of Alumina

AIR CURRENT SEGREGATION
IDENTIFIED MECHANISM
A Langley Holdings Company
26
Claudius Peters Projects GmbH
AIR CURRENT SEGREGATION
PRINCIPLE PATTERN
Separation by drag forces on the individual particles.
Particle below 50 µm may be carried by the air
flows,
Settles out when air flow slows down or changes
direction.
Found to be dominant when handling Alumina
A Langley Holdings Company
27
Claudius Peters Projects GmbH
AIR CURRENT SEGREGATION
COURSE OF EVENT
Segregation means local changes
in the grain size distribution,
separation into
fine and coarse material particles

Conclusions
Minimizing segregation in alumina storage
silos has been improved with the development of a charging and
discharging technology.
- Filling the silo with vertical installed AS-Tubes
- Blending with differentpattern layers on silo bottom
- Sectional discharge flow through silo bottom

Operational Results
• Preventing foreign particles entering the transport system (Screening)
• No grain abrasion and no grain fracture
• Slow alumina conveying velocity, no grain destruction and no scaling
• Closed system and controlled material flow and no dust emission
• No leakage or material spillage within the potroom area
• PLC monitor and record the status of material conveying & distribution
• Energy saving due to intermittend feeding
