Fluidized bed sand dryer

Nov 16, 2021

Fluidized bed dryer has a high drying rate and the material is dried in a very short time. Material remains free-flowing and uniform. FBD bags are finger-like in structure to increase the surface area of the drying bed that helps to increase the drying rate and decrease the drying time during the fluidized bed drying process
