Wet Media Milling. Particles are dispersed in a liquid slurry and media milled to obtain a uniform particle size distribution. The shearing forces (tearing apart), impacting (crushing by outside forces), and attrition (tearing and crushing each other apart) create particle THE EFFECT OF STIRRED MILL OPERATION ON PARTICLES ,Grinding performance is assessed by analysing particle size reduction and energy consumption. Breakage mechanism is evaluated using the state of the art morphological analysis and liberation. Finally, theoretical evaluation of particles flow, types of forces and energy distribution UNDERSTANDING THE EFFECT OF GRANULATION AND ,Particle size distribution needs to be controlled, as it affects the drug bioavailability and also tablet compaction. To avoid uneven granule size distribution, milling is done post granulation. There are different kinds of mills such as hammer mills, ball mills, conical screen mills
