READY-MADE DUSTFREE PARTICLES BY SOLIDIFI CATION OF LIQUID MELTS

Grainy instead of powdery materials are favoured regarding the safety and hygiene in the handling using disperse solids especially if they a re toxic or polluting media. Additionally the grained materials will s upport the possibility for the automation of downstream processes [1]. The solidification of drops by crystallization is one method of produ cing granular materials. The aimed properties of solidified particles have to be maintained by the product for a certain time. It is therefo re of interest, that the dust content is not increasing due to the han dling. In the following the crystallization effects will be discussed which are influencing the solidification of drops if crystallization i s present at all.
