How to Maintain Motor and Rotor of Compound Crusher

The efficient compound crusher produced by Henan Hongxing Mining Machinery has introduced the foreign advanced technology and combined with the demand of the domestic crushing market. The compound crusher is a kind of efficient, energy saving and environmental crusher machine, which is also the common crusher machine used in the crushing production line and the sand making production line. At present, the new generation of the compound crusher is widely used in the cement, mining, building materials and other fields, which has received unanimous praise from the customers at home and abroad. 

The composite crusher works in the harsh conditions for long term, which has exacerbated the attrition of the bearing of the rotor. The crusher machine can not work without the rotors. The rotor is irreplaceable in the operation of the crusher machine. In addition, the rotor is also easily damaged. The bearing of the rotor is very expensive, and the replacement is very difficult. The damage often causes the production losses. Therefore, in the day-to-day using process of the rotor, we have to take effective measures to extend the service life of the bearing of the rotor of the composite crusher. 

First of all, we should make right choice when we select the model of the bearing of the compound crusher. The double row spherical roller bearings have the advantages of strong bearing capacity and perfect aligning performance. Therefore, the double row spherical roller bearing is ofen chosen as the bearing of the rotor of the compound crusher. In addition, the service life of the bearing should be 5000h to 10000h. 

Secondly, we must improve the force status of the bearing of the compound crusher. The impact load acting on the bearing depends on the impulse on the rotor and the support flexibility of the bearing seat. Increasing the support flexibility of the bearing seat will reduce the impact load acting on the bearing. To do this, we can add a rubber pad with appropriate thickness between the bearing seat and the support frame board in order to improve the support flexibility of the bearing seat. Since the rubber plate added increases the support softness, part of the vibration energy is absorbed, which can improve the stress condition of the bearing to achieve the purpose to prolong the service life of the bearing.
