Micronization in the pharmaceutical industry

Micronization is the process of reducing a bulk solid material's particle size to the micron or submicron level. This article discusses dry powder milling techniques and their effectiveness for micronization, specifically in the pharmaceutical industry. The article looks at how mechanical, ball, and jet mills stack up against each other.

Properties of pulverized kaolin particles via ball

Kaolin particles were pulverized in order to reduce the size by using high-energy ball milling under various ball-to-powder weight ratios. The elemental composition and particle size analysis of milled kaolin particles were carried out using X-ray fluorescence and Zetasizer particle size analyzer. The increased in ball-to-powder weight ratios have raised the amounts of oxide minerals such as K
