Generate added value through granulation and composite forming by spray drying

In advanced materials research, spray drying on a table-top instrument is a common technique used for granulation and to form composite materials. The Mini Spray Dryer B-290 is a proven, reliable solution to process water- and solvent based solutions and suspensions into powders with exceptional properties.  

Granulation by Spray Drying

  • Increases flow ability
  • Facilitates handling


Granulation refers to the process of forming granules out of fine particles. Granules of several µm can be achieved by mixing very fine raw material with solvent, binders and dispersants and subsequent spray drying.

Application possibilities of spray dried granules

Transparent ceramics after pressing, calcination and vacuum sintering



Bone and tooth implants after uniaxial compression and sintering



Coatings after thermal deposition on surfaces


Composite forming by Spray Drying

  • Introduce new, desired properties to a material
  • Reduce undesired properties of a material


Composite forming by spray drying refers to a process which results in granules made up of more than one constituent. The composite forming process is used to gain materials with improved properties.

Application possibilities of spray dried composite granules

Anode and cathode materials in lithium-ion battery applications



Highly porous particles after sintering and calcination



Grinding media and cutting tools after pressing and sintering
