La fragmentation des solides (ou comminution) est la réduction par un procédé industriel ou de laboratoire de matières solides en éléments ou particules de taille inférieure et de granulométrie déterminée.
ContactCours de fragmentation des solides: introduction. Les opérations de fragmentation, qui conduisent à réduire les dimensions caractéristiques d'un matériau solide, peuvent avoir divers objectifs parmi lesquels on peut citer de faciliter le stockage, le transport, le triage, le mélange ou la dissolution, la réactivité chimique (liste non limitative).

ContactLa fragmentation des solides est la réduction subie ou provoquée de matériaux solides en éléments ou particules de taille inférieure. Elle peut être provoquée dans le cas du broyage, où l'on cherche à atteindre une granulométrie donnée à moindre coût énergétique.
ContactMar 10, 2006 La fragmentation est l’opération par laquelle on cherche à réduire la taille et/ou à augmenter la surface spécifique de particules solides. Ce phénomène résulte de l’action d’un champ de contraintes engendré par des forces de contact (compression, cisaillement, torsion, flexion, attrition, plus rarement traction). Son efficacité est toujours évaluée par une mesure de l

ContactJun 10, 2007 La fragmentation des minéraux industriels et de matériaux non minéraux, ou de matériaux composites en vue du recyclage consiste à réduite la matière première en une poudre, possédant des caractéristiques spécifiques lié à son emploi dans l’industrie. Pour obtenir une matière très divisée, le broyage doit être poussé et combiné avec la classification. Ainsi, la principale
ContactCette thèse aborde la fragmentation d’un milieu lui-même divisé, en l’occurrence, un liquide visqueux contenant des billes ou fibres solides interagissant uniquement mécaniquement. Des expériences sur des ponts et jets capillaires étirés permettent de distinguer un étirement newtonien du jet de sa brisure catastrophique résultant d’effets de taille finie.
