Spray drying is a widely used processing technique in many manufacturing sectors, including the ceramics sector, for transforming liquid suspensions into free flowing powders.

The module describes:

  • The basic principles of spray drying
  • Advantages of spray drying over other granulation techniques
  • Choosing the right spray dryer for a specific application
  • Preparation of a ceramic suspension for spray drying
  • How to operate a spray dryer
  • Choice of the correct binders and plasticisers
  • How to ensure a uniform granulate for pressing is produced.

The practical session will include:

  • The rheological set-up of ceramic suspensions for spray drying
  • The addition of binders and plasticisers
  • Measuring the properties of spray dried granulates.

At the end of the module you will be able to understand:

  • How spray drying is utilised in the preparation of ceramic bodies
  • The spray drying processing route and equipment
  • How to characterise and control the properties of spray dried granulate
  • The advantages of spray drying over other granulation techniques.
