It is advisable that each of the shock absorbers be fashioned as a system of .... e.g. ores, between two crushing jaws having a force controlled by resilent ties...
The analysis of design solutions used in vibrating jaw crushers reveals that in most cases jaw vibrations are induced by two- or four-mass inertia vibrators 2, 3. Vibrating jaw crushers operate mostly below the range of natural frequencies0/ 0.6-0.8 (0 natural frequency of vibrations) so the jaw lead increases with an increase in the jaw vibration fre-quency, in
Spectrumtec Vibration Analysis Jaw Crusher. Jaw crusher . A jaw crusher breaks down material between a stationary fixed jaw and a reciprocating swing jaw. Oscillations can be small, as material is broken down with multipe impacts. A flywheel creates an eccentric motion with enough interia to crush the ore.
Jun 25, 2019 A numerical analysis of synchronous modes of crusher vibrations with different asymmetries of the initial location of the processed medium relative to the jaws is done. It is shown that for given oscillation excitation frequencies, the non-simultaneous contact of the processed medium with the jaws can lead to a change in the types of synchronous vibrations
resonance vibration caused by overlapping of the excitation (crusher rpm) frequency and the first natural vibration mode. The natural frequencies must be shifted away from the excitation frequency in order to enable safe operation of the crushing station. The basic equation for natural frequency calculations 0 Hz is presented below 0 k m, (1)
