The rotor parts of the crusher all - directional relief

Crusher every part is very important, every part in the use of the crusher are playing a very important role, whether the crusher can be used normally, and we usually on its maintenance and the regular maintenance between the parts have a great relationship. Today's talk is a lot of friends do not pay attention to the rotor problem.

1. What are the main parts of the crusher rotor?

The crusher rotor is mainly composed of spindle, hammer disc, hammer head, hammer shaft, spacer, locking device, bearing, bearing seat, sealing device, pulley and so on.

2. Where is the main distribution of the dangerous area of the crusher rotor?

According to the simulation stress analysis cloud diagram made by the finite element structural analysis, it can be clearly seen that the danger area of the crusher rotor is mainly distributed in the handle of the hammer head, the shaft hole of the hammer disc, the external aid of the hammer disc, the hammer shaft and the primary level of the spindle bearing position, shaft shoulder.

3. Why should rotor work analysis, life prediction and planned overhaul be performed regularly?

Crusher through the high-speed rotation of the hammer head, impact and grinding crushing limestone, because the equipment in the work for a long time by the impact of materials and friction, inevitably make the components of the rotor wear, deformation, damage and loss of normal working ability. If do not analyze the working state of the rotor and predict the life, to do planned maintenance, overhaul, once there is an emergency, it will cause serious loss to the enterprise production line.

4, transition wear crusher rotor main fault performance what?

The main faults of the crusher are serious wear of the shaft hole of the hammer disc and the outer edge. Hammer shaft fracture, hammer disc cracking, locking device failure, spindle displacement, bearing heating, serious bearing damage, spindle deformation or even fracture.

5. What is the main content of rotor overhaul?

The main contents of rotor overhaul are: hammer crusher hammer shaft, spindle inspection and bending repair straightening, locking device inspection repair, rotor hammer disc outer edge repair or replacement of hammer disc, crusher hammer head repair, replacement and grading, bearing, bearing seat, sealing device cleaning maintenance.

6, what is the main content of the crusher rotor hammer disc repair?

Install hammer disc. Pay attention to check the fit of keys and keyways and make sure that each hammerhead fits each other. Check whether the locking device is out of order and replace it if necessary to prevent the hammer disc from moving and the spindle from shifting.

7. What are the main contents and matters needing attention of rotor spindle repair?

Due to the large shaft neck, difficult heating, long heating time, and temperature is not easy to control evenly, the following five points should be noted when using cold straightening method:

Rotor problem a lot of people usually do not care, until there is a problem will find its importance, every part of the crusher is very important. We can't favor the most important places. Every place should be treated equally and maintained the same way.
