Fluid bed testing

We can use different fluidization set-up’s capable of handling several grams of material and equipment that can handle up to approx. 1-2 kilograms of material. These set-ups can be used to assess the following variables:

  • Minimum fluidization velocity
  • Minimum bubbling velocity
  • De-aeration time

All these parameters describe the fluidization capability and the floodability properties of the material under investigation.

The fluidization set-up can also be used to study potential wear of the material due to attrition by means of the release of fines from the bed or assessment of the intrinsically present fines that become fully airborne during fluidization.
