The size reduction operation can be divided into two major categories depending on whether the material is a solid or a . It was found that the milling range covers the It is an alternative to the hammer mill or other forms of pharmaceutical grinding mills. This article discusses dry powder milling techniques and their effectiveness for micronization, specifically in the pharmaceutical industry. The KEK Cone Mill is globally recognised as one of the most versatile size reduction milling machines, due to the wide range of materials it processes. • Two terms used interchangeably in the pharmaceutical industry are mixing and blending. Milling is a common method used in the pharmaceutical industry for particle size reduction to improve the solubility and subsequently bioavailability of low aqueous soluble drugs . What is milling?
You will mill the active ingredients and the excipients. Increasing API wetted surface area provides pharmaceutical companies with a mechanism to regulate dissolution and correspondingly, bioavailability. The milling chamber is charged with the milling media, water, drug and The KEK range includes the widest available, from lab through to bulk production and are widely used in the food processing industries, as well as pharmaceutical and chemical processing. into a material with the required physical characteristics.
