The DEM simulation results indicated that DEM is a promising tool for the simulation of the dynamic particles motion and interactions within planetary ball mill. These results could be utilized to further develop the synthesis performance, anticipate the reaction, and reduce the wear in the dry milling reactions.
The first flowsheet simulation methods and frameworks were developed for modeling of liquidvapor systems [24], [25].The necessity to distinguish between processes for manufacturing of products in fluid or solid form has been pointed out by different authors [2], [23], [26], [27], [28].One of the most decisive differences is the characterization of the material.

Objectives. At the end of this lesson students should be able to: Explain the grinding process. Distinguish between crushing and grinding. Compare and contrast different type of equipment and their components used for grinding. Identify key variables for process control. Design features of grinding equipment (SAG, BALL and ROD MILLS)
This flowsheet demonstrates the use of multiple Kmodels. The SRKUMR equation of state is used for the hydrolysis of the oil into fatty acids and the separation in C12, C14, C16, and C18 acids. Note that the C18 fatty acids are not lumped but split out over three fractions of Lineic, Linoleic, and Stearic acids.

When the test ball mill is run in open circuit the design feed rate is tonnes/hour. Figure 4 compares the predicted size distributions from the open circuit ball mill with feed rates of, and tonnes/hour respectively. As might be expected, the larger the feed rate the coarser the grinding mill discharge product.
