White paper on powder caking

21 January 2015

Freeman Technology has published a white paper that describes extensive experimental studies examining the multiple mechanisms that lead to powder caking. Caking is a routinely encountered problem within powder handling applications, which compromises productivity and increases waste.

The paper ‘Investigations into homogeneous and non-homogeneous caking and crusting in powders using powder rheology’ demonstrates how dynamic powder testing can be used to quantify caking behaviour under different environmental conditions. The resulting data support the development of strategies that reduce caking and maintain optimum powder processability. The paper can be freely downloaded from the Freeman Technology website: http://bit.ly/IHNHCCPPR.

Caking is the result of an increase in the strength of particle-particle interactions in a powder and is caused by exposure to temperature, humidity and/or stress.
