The wet ball-milling tests were conducted at different rotating speeds (20, 25, 35, and 45 rpm) using the 20-mm balls. Figure 7a shows the wet ball-milling separation results in n-butyl acetate. Complete separations are achieved within 90, 70, 60, and 50 min of wet ball milling at rotating speeds of 20, 25, 35, and 45 rpm, respectively.

Ball milling of pure drug mixtures have also been investigated. More recently, ball milling of a combination of two BCS Class II drugs, simvastatin and glipizide, resulted in the formation of stable co-amorphous mixtures . Despite the efficiency of ball milling for size reduction or amorphization, it is less amendable to scale up.
