                              How to Prolong Service Life of Impact Crusher Rotor Bearing?

                              It is quite important to take effective measures to prolong the service life of the IMPACT CRUSHER ROTOR BEARING. The following are some notes about that:

                              3d百位振幅遗漏走势图 1) Reasonably adjust the coordination relationship between the rotor bearings

                              Since the inner ring keeps rotating during the work, it is better to make the inner ring tight, so that the maximum force point won’t be the same point.

                              3d百位振幅遗漏走势图 While the outer ring is relatively fixed, loosing it may cause a small movement under the impact force, increasing the maximum force points, thereby prolonging the service life.

                              3d百位振幅遗漏走势图 2) Improve the balancing accuracy of the impact crusher rotor bearing

                              If the rotor diameter is small, it could be useful to change the mass of the blocking plate on rotor’s both sides; if the diameter is large, the balance weight can be welded onto the outer wall of the rotor. In order to prevent the balance weight falling during the vibration process, make several rows of grooves in proper place, then embedding and welding weight in, firm and beautiful.

                              3) Select the model of impact crusher rotor bearing correctly

                              3d百位振幅遗漏走势图 Double-row radial spherical roller bearing has the advantages of strong bearing and good self-aligning performance, so choose them as rotor bearing.

                              4) Improve the stress condition of the impact crusher rotor bearing

                              Increase the flexibility of the bearing seat to reduce the impact load on the bearing. A rubber plate with proper thickness can be added between the bearing seat and the support frame, to improve the flexibility.

                              Compared with the hammer crusher, the rotor of the impact crusher has greater power with lower energy consumption, suitable for crushing harder materials. The rotor is an important part of impact crusher. Proper use and reasonable maintenance can effectively avoid rotor failure and reduce the bad influence on production.
