Fluid beds

Metso Outotec has over 30 years of fluidized bed history and has over 200 systems installed under the Pyrotherm, Svedala, and Allis Chalmers brands.  Metso fluid bed technology has a proven track record of excellence and has a lower CAPEX and OPEX versus other cooling, drying, heating, and calcining technologies.

• High throughput rates – up to 600 tph

• High rates of heat exchange

• Does not overheat individual particles

• High levels of intermixing of the particles

• Is suited for powders, granules, agglomerates, and pellets 50- 5,000 micron

• High energy efficiency

• Mechanical simplicity

• Continuous operation

• Low maintenance (no moving parts)

• System is automatic and does not require constant operator presence.

Stand-alone or complete systems

The fluid bed technology is applicable in a multitude of industries and minerals processing such as mineral sands (ilmenite,rutile, zircon, leucoxene, garnet) iron ore drying, diatomaceous earth, phosphates & potash, lithium spodumene, lime and various other industries.

Fluid bed technology can be for stand-alone units or complete systems deliveries including PLC control, dust/product collection, product conveying (feed and discharge), exhaust gas handling, heat exchanging, and fuel delivery systems.

Efficient heat transfer process

The introduction of an appropriate air flow into the system brings about the onset of fluidization.  The air flow passes through the bed of material and suspends the particles in a fluid state.  The bed has the appearance of a vigorously boiling liquid, and will flow steadily through the vessel from one side to the other and discharge over a set weir plate or bed level control feeder. Each particle is suspended by its own pocket of gas maximizing the heat transfer rate.  This results in an extremely efficient heat transfer process.

Applicable industries:

• Mineral and coal applications

• Iron ore

• Plastic and polymer

• Limestone

• Potash & phosphate industries

• Rare earth elements
