Using the Discrete Element Method for Predicting the Mixing Behavior of Gravity Blenders in Different Operation Modes

“…Results achieved by simulations often were in good qualitative accordance with experimental data [8,9]. The DEM is applied in this paper to simulate the performance of a blender in continuous mode avoiding comprehensive time-and cost-consuming experiments as conducted by, e.g., Eichler, Dürr et al, and Härtl [1,8,9].

“…5 presents the residence time density distribution as a function of the insert height of the BINSERT blender measured by Eichler und Dürr et al [1,8]. 5 presents the residence time density distribution as a function of the insert height of the BINSERT blender measured by Eichler und Dürr et al [1,8].…”

“…The investigated dimensionless insert heights were z/d shaft = 0.4 (Fig. The residence time density distributions determined by the simulations are illustrated compared with the measured residence time density distributions by Eichler [1] and Dürr et al [8] in Figs. 7), respectively.…”

“…Eichler and Dürr et al determined various residence time density distributions within their investigations [1,8]. The properties of the bulk materials used are presented in Tab.…”

“…Dürr et al [8] applied the DEM for investigating blending tasks by comparing the results gained in pulse experiments with numerically determined ones. They could achieve a good qualitative agreement showing the proof-of-concept.…”
