Abstract The vibrations of a vibrating jaw crusher model, excited by two self-synchronizing unbalanced-mass vibration exciters, with allowance for the interaction with the processed medium are examined. It is found that the frequency range of stable antiphase synchronization of the exciter rotation required for normal operation of the crusher, depends …
