• speed of rotation of the mill; • slurry density in case of wet grinding operation. Quantitative estimations of these parameters can be found in [4, 5, 23]. An important characteristic of an industrial ball mill is its production capacity which is measured in tons of production per hour. The production capacity depends
In ball milling, the desired particle size is achieved by controlling the time, applied energy, and the size and density of the grinding media. The optimal milling occurs at a critical speed. Ball mills can operate in either a wet or dry state.
milling in a planetary ball mill on its parameters. Kakuk et al. (2009) modelled the milling process in a planetary ball mill and found a relationship between the angular velocity of the sundisk and the vials, and the geometrical parameters of the mill. Farahbakhsh et al. (2011) investigated the mechanical alloying of
Ball milling of pure drug mixtures have also been investigated. More recently, ball milling of a combination of two BCS Class II drugs, simvastatin and glipizide, resulted in the formation of stable co-amorphous mixtures . Despite the efficiency of ball milling for size reduction or amorphization, it is less amendable to scale up.

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.
Mar 11, 2016· Media milling is known as the 'classical' wet milling technique; this process treats a dispersion of concentrated drug in an aqueous or non-aqueous 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.
