Continuous Fluidized Bed Spray Granulator with Air-classifying Product Discharge “Mixgrad” combines the technology and know-how of a circular type fluid bed dryer and a granulator coater. It can be used to perform continuous granulation (agglomeration) of powder and mixing or adsorption of liquids and powders for improve end product quality.

The granulation process occurs by agglomeration of the powdery particles which due to the sprayed solution will closely bond together in order to form the granules, resulting in a decrease of porosity and increase of density.
The granules are easy for handling, difficult to break during transportation as well as easier to dissolve when added to a liquid.

The specially designed air-classifying device narrows the particle size distribution. The fine powder is sent back to the fluidized bed and only the granules will be discharged.

Batch model also available.
