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 significantly on the gap between the

Jaw crusher movement is guided by pivoting one end of the swinging jaw. and an eccentric motion located at the opposite end. [4] The size of a jaw crusher is designated by the rectangular or square opening at the top of the jaws .For instance, a 22 x 30 jaw crusher has an opening of 22" by 30", a 46 x 46 jaw crusher has a opening of 46" square.
