  • Ball Milling to Build the Hybrid Mesocrystals of Ibuprofen

    Also, it has been recently employed in studies on drug formulation to utilize controlled dissolution of the drug domains. In this report, ibuprofen was attempted to form hybrid mesocrystals with calcium carbonate crystals. Two polymorphs of calcium carbonate (aragonite and calcite) were used during the solidstate process of ball milling.

  • Dry Grinding VS Wet Grinding Mineral Processing & Metallurgy

    The choice between wet and dry milling is, in general, unimportant in smallscale milling but is a major technical problem when largescale milling in the metallurgical industries is involved. On purely mechanical grounds it is difficult to see any great difference in fundamental principles between wet and dry milling, since dry milling may be regarded as wet milling with a fluid having the
