1.2.1 Wet Stirred Media Milling and Formation of Drug Nanosuspensions A popular approach for the bioavailability enhancement of poorly water-soluble drugs is particle size reduction. Reduction in particle size leads to an increase in the specific surface area of the drug particles, which in turn improves the dissolution rate (Noyes and Whitney
Examples of ap- plications are fillers for paper and plastic coatings, pigments, ceramics for abrasive and structural applications, toners for photocopy and printing machines. Besides the direct synthesis of these materials by chemical methods, wet grinding in stirred media mills is a suitable method for the production of sub-micron particles.

Stirred media mills are widely used in industry for fine and ultra-fine grinding of various materials and dispersion of aggregates. There is a growing interest in the large-scale production of nano-size particles, and wet stirred media milling appears to be a promising technology in this regard.
with ceramic grinding media of various compositions being generally employed. Efficiency of operation, stirred mill type, and quality control are important factors in this selection of media; but the major reason has been the relative hardness compared to feed materials in MIG stirred milling installations. Stirred milling technology Background
Stirred Mills – Ultrafine Grinding - ScienceDirect. Figure 10.1 shows the difference in energy efficiency between a laboratory ball mill and a stirred mill grinding a gold ore using 6 mm diameter alumina balls as media. At a fine grind size there is a clear advantage in energy consumption for a stirred mill over the tumbling mill.
Nov 10, 2016In ultra-fine wet grinding the situation is further complicated due to the presence of the solvent: reactions of the stressed solid with the surrounding liquid phase can occur. In this paper several aspects of mechanochemistry occurring in stirred media mills are outlined through suitable experiments.
The finer the product required, the more efficient stirred mills will be than a ball mill. The attrition grinding action, vertical arrangement, and the finer media size distribution contribute to make stirred mills more energy efficient grinding machines.
The results show that the pre-treatment of the material with the HPRM could result in energy saving and efficient size reduction during the subsequent wet ultra-fine grinding in the stirred bead mill. It was found that the level of fineness of the ground product is dramatically influenced by the number of repeat passes of pre-grinding in the HRPM.
