Modeling of TwoPhase Flow in WSMM: CFD, DEM, and Their Coupling. In a stirred mill, drug particles and beads suspended in an aqueous solution of stabilizers are stirred by a rotor (refer to Fig. 1).As drug particles are typically orders of magnitude smaller than the beads, the drug suspension has been exclusively treated as a single, equivalent liquid phase with Newtonian behavior, whereas ...

Recommended media charge : 70 75% of mill's useful vol. Calculation of media load : Example : Attritor mill net volume is 50 Ltr charging with Ø 8 mm balls. 70% of mill's vol = 35 Ltr x kg/Ltr (bulk density of Steatite media). That is 56 kg of Steatite grinding media is required for 50 Ltr capacity attritor mill.
