Ball milling is a technique traditionally used in the metallurgy and mineral industries that aims to grind or blend powders 259 the rigid balls typically made of highhardness materials such as ceramics flint pebbles and stainless steels collide with each other together with powders within a closed chamber

A ball mill also known as pebble mill or tumbling mill is a milling machine that consists of a hallow cylinder containing balls mounted on a metallic frame such that it can be rotated along its longitudinal axis the balls which could be of different diameter occupy 30 50 of the mill volume and its size depends on the feed and mill size

Media milling is known as the classical wet milling technique this process treats a dispersion of concentrated drug in an aqueous or nonaqueous liquid medium with milling balls the process is advantageous in its economic value and ease in scaling up however there are also significant drawbacks to this method

Apr 21 2016 different wellknown types of milling techniques with both advantages and disadvantages dry and molecules however wet milling has some disadvantages as well eg increased wear of the grinding has recommended the combination of planetary ball milling as dry milling and pearl milling
