Apart from its comminution function, ball milling also serves as an intensive mixing technique capable of producing co-ground drug-excipient mixtures comprising amorphous drug forms intimately mixed ...

Ball milling glass is a crushing technique that crushes nanotubes into very fine powders. During the ball processing process, the impact between the minuscule unbending balls in a hid compartment will produce confined high tension.

In dry milling, about 25 vol% of powder is added along with about 1 wt% of a lubricant such as stearic or oleic acid. For wet milling, 30-40 vol% of powder with 1 wt% of dispersing agent such as water, alcohol or hexane is employed. • Optimum diameter of the mill for grinding powders is about 250 mm Ball Mill
