Powdermatrix Faraday Partnership holds first interactive session on spray granulation.

The Powdermatrix Faraday Partnership has held its first interactive session on spray granulation.

The half-day session, which highlighted improvements in materials processing, was held at Ceram, the Stoke-on-Trent based centre for materials and technology.

Problems encountered during spray drying are often solved locally in a way that does not read directly across into other systems or other materials.

But there are many instances where methods are more generic and can be said to constitute best practice.

The Powdermatrix Interest Group for members aims to help share this best practice in spray drying, and develop a better understanding of the influences that powder suspension properties have on the performance of the granulate produced.

Speakers at the event included Ian Wilson, Department of Chemical Engineering, Cambridge University, who reviewed the recent developments in spray granulation coming from UK universities.

These advances have had an initial impact on the pharmaceutical and food industries, but have a high relevance to the materials sector.

Peter Hancock of Ceram discussed slip flow properties and their effect on the spraying process and final product, while Steve Kessel, also of Ceram, overviewed the effects and impacts that binders and additives have on the quality of the granulate produced.

Potential alternative water based environmentally friendly binders were also highlighted.

Discussions identified contact with suppliers and atomisation of complex slurries as areas of interest for future group activities.
