It is the best option of size reduction when impaction, attrition or compaction type milling is not effective especially for tough, fibrous or resilient materials. It is easy to install, operate and maintain. The equipment is not expensive; Disadvantages of Cutter Mill. Cutter mill is not suitable for most pharmaceutical applications due to the ...
Effect of impaction between the milling media and drugs gives essential energy for disintegration of the microparticulate system into nanoparticles. In this process, the chamber of milling is charged with the milling media involving drug, stabilizer, and water or suitable buffer, which is rotated at a very high shear rate to generate suspension.
Fluidized Energy mill, also known as micronizer or jet mill is a type of mill that consists of a hollow toroid which has a diameter of 20200mm depending on the height of the loop which can be up to 2m.
Technology advancements in milling now enable the production of drug micro and nanoparticles on a commercial scale with relative ease. This review will provide a background on milling followed by the introduction of common milling techniques employed for the micronization and nanonization of drugs.
Oct 21, 2009· Introduction: Milling is the cutting operation that removes metal by feeding the work against a rotating, cutter having single or multiple cutting edges. Flat or curved surfaces of many shapes can be machined by milling with good finish and accuracy. A milling machine may also be used for drilling, slotting, making a circular profile and gear cutting by having suitable attachments.
