ball milling in pharmaceuticals

Les concasseurs à mâchoires ne fonctionnent généralement pas indépendamment, mais avec les concasseurs à cône, les concasseurs à percussion, les machines de fabrication de sable, les tamis vibrants, etc., constituent un ensemble complet de systèmes de traitement du sable et du gravier pour obtenir un traitement précis du minerai et de la roche et améliorer la pertinence du produit, Augmenter sa valeur marchande.Les lignes de production courantes sont: la ligne de production de pierre et la ligne de production de sable.

Ligne de production de pierre

Sur la base de la ligne de production de pierre, un équipement de machine de fabrication de sable pour le concassage fin et le façonnage est ajouté, ce qui permet de réaliser la production simultanée de sable et de pierre concassée fabriqués à la machine. peut répondre aux diverses exigences de traitement des clients., Pour atteindre l'objectif "d'une ligne à usages multiples", c'est un choix de ligne de production idéal pour produire des matériaux de surface d'autoroute, des agrégats de sable et de gravier de chemin de fer à grande vitesse, du sable et du gravier de la centrale hydroélectrique matériaux, terminaux portuaires et pistes aéroportuaires.

2015-7-1  Ball milling of pure drug mixtures have also been investigated. More recently, ball milling of a combination of two BCS Class II drugs, simvastatin and glipizide, resulted in the formation of stable co-amorphous mixtures . Despite the efficiency of ball milling for size reduction or amorphization, it is less amendable to scale up.

Ball size or ball mass – what matters in organic ...

Ball mass is an important parameter that is known to have an influence on the outcome of a mechanochemical reaction induced by ball-milling. A standard way of modifying the ball mass is to change the size of the ball made of the same material. In this case, however, a change in mass is accompanied by a simul Editor’s Collection: Mechanochemistry The Solid State of Pharmaceuticals
