Causes Of Failure And Solutions from 's blog
1. Host rollover
In the process of hoisting the jaw crusher's main engine, rollover occurs, which makes the eccentric shaft bend under unilateral force. In serious cases, it is necessary to replace the main engine immediately and strive for new hoisting replacement.
2. Material hardness exceeding standard
If the material given is too hard, it will cause eccentric shaft bending if it exceeds the maximum range of jaw crusher. Therefore, material hardness should be controlled and suitable crusher should be selected according to the compressive strength of crushed material.
3. Elbows do not meet the standard
When this kind of situation occurs, it should be checked in many ways. It is strictly forbidden to use elbow plate and elbow pad which do not meet the design standards.
4. Improper heat treatment of eccentric shaft
When the heat of eccentric shaft does not disperse in time, it will easily lead to short-term fracture; the appropriate method at this time is to replace the new eccentric shaft and use the eccentric shaft qualified for heat treatment.
5. Long-term overload operation of main engine
It is necessary to shut down the machine in time for maintenance, adjust the working load or replace the suitable crusher.
