Jaw crusher maintenance

(A), the preparatory work before moving over
1, small check is good lubrication of bearings, bearing plates and elbow joints have enough grease.
2, should carefully check all fasteners are securely fastened.
3, check the drive belt is good, found a broken belt shall be updated with the phenomenon.
4, check whether the ore crushing cavity or other debris, if debris should be removed to ensure that the machine no-load start.
5, check whether the bolts from the top to return, gasket compression, T-bolts are tightened, should be noted that non-crushing machine at work from the top bolt and adjust the seat contact.
(B), the start crusher
1, the checks to prove that part of the machine and drive the situation properly, before they can start.
2, the series crusher can only start with no load.
3, the start, we must use a bell or other signal prior notice.
4 starts, if found to have abnormal situation, should immediately stop operation, to identify and eliminate abnormal situation, only to restart the crusher.
(C), use and maintenance of crusher
1, crusher normal operation only after the feeding began.
2, the crushing of materials should be uniform to join the crushing chamber, the side feeding should be avoided or filled with feeding, to prevent overloading or under unilateral overload.
3, under normal circumstances grinding mill, the bearing temperature rise of not more than 35, the maximum temperature does not exceed 70, as more than 70 should be immediately shut down, find out the cause to be removed.
4, stop, you should first stop feeding the work material to be broken completely discharge chamber was broken only after the turn off the motor.
5, in broken when, if the issues caused by broken cavity stop blocking material should be immediately shut down the motor, the material must be removed only after the restart.
6, tooth wear plate at one end, you can turn around to use.
(D), crusher lubrication
1, the constant attention and lubrication wear a timely manner, can guarantee the normal operation of the machine and extend the service life.
2, the grease used crusher, according to the use of the machine temperature, location and other conditions to decide. General use of calcium-based, sodium or calcium sodium based grease.
3, add bearing grease to 50-70% of volume, stone crusher must be replaced once every three months, for grease application of clean gasoline or kerosene, carefully cleaning the roller bearings.
4, elbow pads touch plate and bracket, the machine must be filled in the grease before starting.
