[en] The attempt to compare between each other various construction variants of the centrifuges, methods for calculation and modelling, mechanical, electronic and electrophysical methods of balancing and damping of oscillations was made. The productivity of the rotor with the task exterior parameters, the algorithms for choosing geometric parameters of rotors and disposition of centrifuges indoors are discussed, the estimation of the productivity of the chosen rotors, specific productivity of the group of centrifuges are made. The estimation of relative and specific cost during the use of being consideration types and sizes of the centrifuges was performed. The dependence of the productivity of rotor from its diameter assumed on the basis of the publications played the noted role in the consideration
