Description
Summary:Vibratory jaw crushers are modern machines for grinding and rock crushing. Single jaw of vibratory jaw crusher is considered in this paper. Phenomenological model of interaction of the jaw and rock is proposed. Two options for considering the power of an unbalanced drive are considered. In the first, an unbalanced vibrator has a constant angular velocity relative to the bed. In the second, the electromechanical characteristics of the electric motor, which drives the unbalanced vibrator, are taken into account. The impact of crushed material on the vibrational modes of the jaw and the rotation characteristics of the vibrator for each of the vibration excitation variants is considered. The distribution of the technological load obtained based on this model over the jaw is shownA post-publication change was made to this article on 20 Mar 2020 to correct an author affiliation.
