The unique, circular configuration of Kason's Fluid Bed Processors allows them to de-dust, scalp, de-lump or agglomerate bulk solid materials that are being dried, cooled or moisturized, according to William Zhao, Chief Engineer. "Kason Fluid Bed Processors equipped with accessories for de-dusting, scalping, de-lumping or agglomerating obviate the initial and operating expense of stand-alone equipment and improve product uniformity while conserving valuable floor space," he says.

The red portions of the diagrams below indicate de-dusting, scalping, de-lumping and agglomerating options available on Kason Fluid Bed Processing Systems. Note that all incorporate a blower for heated, cooled or moisturized air, a fluid bed processing chamber, a material feed source, a cyclone separator and discharge spout.
 

DE-DUSTING

For drying, cooling or moisturizing applications that also require dedusting of the material, cylindrical exhaust plenums can be specified (instead of tapered plenums that reduce air speed), causing fluidized dust to be drawn from the fluid bed chamber into a cyclone or other dust collection device, eliminating the need for a separate de-dusting screener.

SCALPING

For scalping of oversize particles from material before it is dried, cooled or moisturized, the fluid bed chamber can be fitted with an integral, top-mounted screening deck that derives its vibratory motion from the fluidizing chamber's gyratory motors, significantly undercutting the initial and operating costs of a stand-alone screener, while preserving floor space.

DE-AGGLOMERATING

Many materials that require fluid bed processing tend to form agglomerates that can reduce drying/cooling/moisturizing efficiency and/or uniformity of the finished product. In these instances, Kason fluid bed systems can be equipped with integral CENTRI-SIFTER^® centrifugal screeners for continuous de-agglomerating of incoming material.

AGGLOMERATING

Kason Fluid Bed Agglomerators employ a spraying system within the fluid bed chamber that introduces moisture to powdered material as it is fluidized, causing particles to form agglomerates on a controlled basis. Fluid bed drying, cooling or moisturizing can be employed concurrently to condition the material, maximizing physical characteristics of the agglomerates as well as production efficiency.
