Description

The slurry or liquid material is continuously fed into the fluid bed chamber which is filled with 1-3mm diameter ceramic balls. As soon as the material gets into the chamber it gets quickly dried by the combination of conduction heat from the heated ceramic balls and by convectional heat from the fluidizing heated air.

The inlet material will adhere to the flowing ceramic balls, will get instantly dry and during the flowing of the ceramic balls in the fluidized chamber the ceramic balls will collide with each other detaching the dried product from the ceramic balls’ surface.

As the product gets dried it becomes lighter allowing to be conveyed by the fluidizing air and then discharged through the dust collector or bag filter housing.

This process guarantees a final product fine powder with particle size close to its primary one and extremely low moisture content.

Due to its high efficiency and its compact design “Slurry Dryer” has been widely used for the drying of chemical slurries, ceramic slurries, glass slurries, metals slurries, resin slurries among others.
