Jaw crusher eccentric shaft bending or breaking reasons:
1. Jaw Crusher super-negative long-term operation of the host;
2. Have been broken material hardness of more than product specifications requirements;
3. In lifting the host occur during rollover, so that a unilateral force eccentric shaft bending;
4.Eccentric shaft improper heat treatment, stress concentration, resulting in short-term break.
5. Toggle plate sub-standard, non-broken material into the crushing chamber off the time when self-protection;
Jaw crusher eccentric shaft bending or breaking exclusion methods:
1. Replacement of the eccentric shaft, the use of heat treatment of qualified eccentric shaft.
2.Replacement of the eccentric shaft, do not use inconsistent design standards elbow board, elbow board pad;
3. Replacement of the eccentric shaft, align the work load or replace the broken compatible machines;
4. Replacement of the eccentric shaft, the compressive strength of materials by crushing, choose the corresponding crusher;
5. Replacement of the eccentric shaft, correct lifting host;
