Fluidised bulk density

Fluidised bed The fluidised bed consists of two boxes on top of one another. The top and larger one contains the powder, and the lower one is separated from it by metal mesh and a semipermeable membrane. Air is pumped under pressure into the lower compartment and then diffuses through the membrane and through the powder. The powder particles are lifted and separated by the air. This results in a considerable reduction in the bulk density so that the item to be coated can easily be submerged in the powder. [Pg.747]

Fluidisation may also be used to measure aerated bulk densities, but this technique is normally used to determine the Ergun particle density (see Section 1.4.4). [Pg.8]
