The requirement stipulating high frequencies of jaw crushers' vibrations encourages the use of steel springs, with a very low damping ratio. Therefore, the damping in the considered vibrating system can be neglected. The equation of motion of a jaw in a vibrating jaw crusher shown schematically in Fig 2 can be written as [2]:.
