Jaw Crusher Maintenance

Jaw Crusher Maintenance
 Jaw crusher wear phenomena in daily operations is inevitable, we only have to do regular maintenance can extend the useful life to the maximum. Jaw crusher spindle, eccentric shaft and bearing aspects of long-term maintenance.

 First, the axis of the wear and tear if small, just to fix its geometry, turning in a lathe, so that journal to the correct geometry, then the corresponding reduced bearing diameter. However, after several such treatment, if the journal size reduction of 5% over the original, it does not allow re-turning, but should replace a new shaft.

Second, the jaw crusher is working under the impact load, bearing on the babbitt lining, duration of approximately two years or so, the deadline, you will need to re-cast. If the eccentric shaft and bearings, spindles and bearings are worn, the tip clearance gap greater than 1.5 times the original assembly, the need to adjust or replace the padded; oil groove wear 1.5 mm, oil groove should be reopened and adjusted. Connecting rod head cover and the gap between the eccentric shaft, worn to 1.5 times greater than the assembly space, they need to add a new pad to adjust or replace. When the bearing babbitt on a deeper peel or large scratches, should be re-cast. For the bearing quality after processing the following requirements: babbitt surface color should be uniform, dull, silvery white; babbitt surface layer should not have ash, cracks, blisters, shrinkage and other phenomena and peel
