Nanomilling in a Fluidized Bed Jet Mill. One downside to wet milling is . well, that it's wet. For materials needed in a dry state, a drying step is required after wet milling. Drying, in turn, is followed by a deagglomeration step, since ultrafine particles often tend to clump together when dry. In addition, the dispersing agents often ...

Abstract. Wet ultrafine grinding has been increasingly used for production of ultrafine powders in various industries. It has been known that slurry rheology significantly influences the grindability of industrial minerals in wet ultrafine grinding. This review represents some previous work with respect to slurry rheology in ultrafine grinding.
