Abstract. The airjet and ballmill are frequently used in fine micronization of active pharmaceutical ingredients to the order of 15 μm, which is important for increasing dissolution rates, and also for pulmonary delivery. In this study, we investigated the ability of airjet and ballmill to achieve adequate micronization on the lab scale ...
A new ballmill extraction method for solid dosage forms was developed. It was used for tablets, and compared with a conventional (powdering and sonication) method applied in pharmaceutical analysis of solid dosage forms. The ballmill sample preparation procedure is both quantitative and fast. No p .
After reviewing the information presented in Table 1, Table 2 and Table 3, it can be inferred that a planetary ball mill is the type of mill most commonly used in all three types of drug formulations. Planetary instruments have vessels placed inside a rotating disk and can induce high energy to the powder to prompt changes.
