Jaw crusher can be running under serious working condition. Therefore, pay attention to use of jaw crusher machine, the machine normal operation can be ensured and raise the productivity of jaw crusher.
Before jaw crusher' s starting, we should check ore crushing cavity whether there is ore or debris in. If there is , clean up to ensure jaw crusher start up under no-load condition. Before starting must use bell or signal to carry on the forecast in advance. If there are ore or debris, we should first to start the oil pump motor, and observe whether oil pressure and oil flow indicator is normal, then start the main motor.
Some jaw crusher motor starting capacity is less than with the needs of jaw crusher, the flywheel can be turned a certain Angle with the crane make the connecting rod on an easy start position (the eccentricity above the eccentric shaft).
It needs a certain period after startup to achieve a normal rotary speed. So in the operating instructions shall be prescribed jaw crusher startup time. After starting, no noise or tapping sounds are allowed to feed. Feed should be even and avoid overload.
In jaw crusher operation we should often pay attention to the phenomenon whether the big ore block stuck the mouth. If it is, we should make it out with a hook turn. If the big Ore block the crushing cavity, the feeder should be stopped. Absolutely prohibit that remove the ores from jaw crusher in the crushing cavity with the hands. if there are large ore blocks need be removed, we can use special instruments to take out after parking.
Jaw crusher in normal work, should often check whether all lubricating points lubrication are in good condition. And pay attention to the temperature of the bearing. Especially the eccentric bearing temperature should be no more than 60 y. Should always observe the oil temperature measurement instrument, or use hands to check the temperature rise of bearing. When Oil temperature exceeds the allowed range, jaw crusher should be stopped to check, find out the reasons and eliminate the cause.
Jaw crusher in crushing cavity filled with mineral, parking after an accident, before starting again, must be purged of ore in crushing cavity
