Fluidized bed

A fluidized bed is a physical phenomenon occurring when a quantity of a solid particulate substance (usually present in a holding vessel) is placed under appropriate conditions to cause a solid/fluid mixture to behave as a fluid.This is usually achieved by the introduction of pressurized fluid through the particulate medium. This results in the medium then having many properties and ...
