Technologies to Improve the Solubility, Dissolution and

Dec 04, 2017Micronization of drugs is done by milling techniques using Jet mill, Ball mill, Rotor-stator mill, etc. This approach can reduce particle sizes down to 1 micron. Micronization improved the digestive absorption, and consequently the bioavailability and clinical efficacy of griseofulvin, progesterone, spironolactone and diosmin [9].

Ball Mills

8.3.2.2 Ball mills. The ball mill is a tumbling mill that uses steel balls as the grinding media. The length of the cylindrical shell is usually 1–1.5 times the shell diameter ( Figure 8.11). The feed can be dry, with less than 3% moisture to minimize ball coating, or slurry containing 20–40% water by weight.

Ball mills are the most commonly used piece of equipment for milling. However, vibratory mills, attrition mills, and fluid energy mills also are used. Crushing and grinding typically are dry processes; milling may be a wet or dry process. In wet milling, water or alcohol commonly is used as the milling liquid.

How to Drill Holes Into a Double

Although drilling through the glass in a double-pane window may seem odd, the process can actually remedy moisture problems. As double-pane windows age, the seals can deteriorate and allow moisture to penetrate between the panes. The result is a foggy appearance on the glass as condensation forms.
