L19 - Spray Drying
Spray drying is a widely used processing technique in many manufacturing sectors, including the ceramics sector, for transforming liquid suspensions into free flowing powders. In the ceramics sector spray drying is used to produce granulates for pressing from clay and non-clay body formulations, for the forming of whitewares and technical ceramic items.
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.
