Dynamic Research on Vibration-impact Crushing System of a Bilateral Single-mass

The vibrating roller crusher convert relative vibration generated by two rigid bodies to bring high-frequency impulse on grain layer (or granular) in chamber, which makes grain crush to particle. Based on the science of vibration, dynamics model in vibration-impact crushing system of a bilateral single-mass and vibration differential equations are established. By dynamic analysis, amplitude frequency curve, hysteresis impact curve and energy absorption curve are all founded. The curves on dynamic response are discussed. Under the consideration of their results, displacement, velocity and acceleration with the time history are induced. Impact on the left and right sides are unsymmetrical. Influence laws on amplitude frequency, impact, energy absorption from clearance and vibration frequency is also established.
