    • A process for forming a dispersion of milled solid particles of a compound comprising forming a milling mixture of a liquid medium, milling media having an average particle size of less than or equal to about 300 microns, and a solid compound in a mixing vessel, and agitating the milling mixture with a mixer to contact the milling media and solid compound and to reduce the solid compound to a desired average particle size to form a dispersion of milled solid particles in the liquid medium, wherein the volume ratio of the milling media to the combined volume of the liquid media and solid compound in the milling mixture is less than 1, a rotor-stator mixer comprising rotor and stator elements separated by a rotor-stator gap of greater than the average particle size of the milling media and not greater than about 2.5 mm is employed to agitate the milling mixture in a milling chamber of the rotor-stator mixer, and the solid compound is milled to a volume-weighted average equivalent sphere diameter particle size of less than or equal to about 200 nm. In a preferred embodiment, the milling media is a polymeric resin having a mean particle size of less than 100 micrometers. The method enables significantly reduced levels of milling media and facilitates separation of the dispersion from the milling media in the milling mixture.
    • 用于形成化合物的研磨固体颗粒的分散体的方法,包括形成液体介质的研磨混合物,平均粒度小于或等于约300微米的研磨介质和混合容器中的固体化合物,以及 用混合器搅拌研磨混合物以接触研磨介质和固体化合物,并将固体化合物还原成所需的平均粒度,以形成在液体介质中研磨的固体颗粒的分散体,其中研磨介质与 研磨混合物中液体介质和固体化合物的组合体积小于1,转子 - 定子混合器包括由转子 - 定子间隙分开的转子和定子元件,转子 - 定子间隙大于研磨介质的平均粒度,并且不大于 使用大约2.5mm来在转子 - 定子混合器的研磨室中搅拌研磨混合物,并将固体化合物研磨成体积加权平均当量球 直径粒径小于或等于约200nm。 在优选的实施方案中,研磨介质是平均粒度小于100微米的聚合物树脂。 该方法能够显着降低研磨介质的含量,并促进分散体与研磨混合物中的研磨介质的分离。
