Effect of Milling Parameters on DEM Modeling of a Planetary Ball Mill
Planetary ball mill is a powerful tool, which has been used for milling various materials for size reduction. The discrete element method (DEM) was used to simulate the dynamics of particleThis has been demonstrated by Tavares and King (1998), who showed that fracture energies of particles coarser than about 0.5 mm were higher in the discharge when compared to the fresh feed of a ball mill grinding taconite. This is an indirect evidence of the lower breakage rates of tougher particles inside the mill, which survive the stressingModeling breakage rates of coarse particles in ball mills

The influence of the rotation frequency of a planetary ball mill on
dispersity in a planetary ball mill is common to all powder metal-lurgy. The main parameter for control the milling rate in planetary mills is the rotationalspeed of vials and disc. However,thereBall mills can be classified into high-energy ball mills and low-energy ball mills by their rotation speed. Selection of certain ball mill depends on used technique; MA, MM or MD. However, some ball mills can be utilized for all three of these techniques. Table 2 presents the most common ball mills and their energy types.
