Fluid Bed Dryer, Production Capacity : High

Fluid Bed Dryers: Through the fluidizing phenomenon, the material begins to act like a fluid with gas of the right velocity passed though the bed. There is excellent solids/gas contact, resulting in high heat transfer rates for rapid drying. We have built fluid bed drying systems with a drying capacity up to 300 tph.

Fluid bed dryers are suitable for

• Sands (Mineral & Foundry)
• Minerals (Limestone, Magnetite, Gypsum, Copper, Salt, Iron Ore)
• Plant Seeds & Grains (Grass, Wheat, Oats)
• Chemical Mixtures

Main benefits of the fluid bed are

• Ability to dry small to fine material
• Low maintenance
• Well agitated
• High capacity

Concept of the fluid bed
The bed has the appearance of a vigorously boiling liquid, and in fact the bed of material takes on many of the properties of a fluid. It exerts a hydrostatic head, and the material will flow through a hole in the vessel or over and under a weir within the bed.
Metso has installed over 100 fluid bed systems under the Pyrotherm and Allis-Chalmers brand names.
