There are many common faults of impact crusher, so the solutions are different,

First, if found crusher (back broken) bearing heating:

    Description bearings in oil, the need for timely fuel, of course, also cause excessive bearing heating oil, fuel oil be sure to check, bearing damage, to the timely replacement of bearings, cover tight, to regulate the bolt, an appropriate degree is appropriate.

    Second, if found breaking Crusher (back broken) Abnormal vibration:

    That the material is too large, you can check the feed size. Uneven wear, indicating need to replace the hammer back, rotor imbalance, need to be adjusted, based on improper handling, need to check the anchor bolts and reinforcement.

    Third, as I do now crusher (back broken) belt flip:

    That belt wear, replace belt, transmission belt assembly problems because of its need to be adjusted in the same plane, pulley, belt itself must pay attention to quality.

    Fourth, if found Impact Crusher (back breaking) the particle size is too large:

    Note hammer wear, the hammer adjustment to be busy or replacement, hammer and the back plate of the gap is too large, usually adjusted to 15-20mm, the feed will also affect the particle size is too large particle size.
