Abstract

The  high performance of  the planetary mixers with two vertical axis  is closely related to the degree of prepared concrete homogenization. The freshly concrete homogenization process is influenced by the blades vibrational movements as a result of the alternative bending of the mixer arm, shaped like an embedded elastic beam. In order to homogenization process mathematical modelling, the case of a planetary mixer with a capacity of  2.5 m3 is considered, for which the bending forces and arrows, the own pulsations, as well as the amplitudes of the oscillating movement were analyzed in three cases. In order to make the mixing more efficient, the constructive shape, the resistance module and implicitly the stiffness of the arm-blade system are successively modified, aiming to obtain proper pulsations as close as possible to the excitation pulsations of the system and implicitly with movement amplitudes as high as possible in conditions of maintaining high reliability. The paper therefore aims an analysis of the parameters variation of the arm-blade system vibration movement depending on its elasticity, in order to improve the homogenization process for planetary mixers with two vertical axis.
