We present results concerning the important role of system packing in processes density- and inelasticity-induced segregation vibrofluidized binary granular beds. Data are acquired through a combination experimental from positron emission particle tracking simulations performed using discrete method. It is found that due to inelasticity differences between species most pronounced moderately dense systems, yet still exerts significant effect all but highest density systems. Results disparities particles' material densities show maximal degree which can achieve directly related system, while rate at occurs shows an inverse relation. Based on this observation, method minimizing time energy requirements associated with producing fully segregated proposed.
